10 Questions You Must Ask Before Hiring Any App Developer

June 24, 2025 - 1 hours read

Key Takeaways:

Experience & Track Record: Verify the developer’s experience in mobile app development and review their portfolio. With only 0.5% of apps achieving market success, a seasoned developer who has delivered similar projects can greatly improve your odds.

Process, Communication & Reliability: Ask about their development process, project management, and communication methods. Clear planning (e.g. a discovery phase) and regular updates are critical – 57% of failing projects cite communication breakdowns. A good developer outlines a realistic timeline and budget, as only 16% of software projects meet their time and cost targets.

Quality, Security & Support: Ensure they prioritize app quality, security, and post-launch support. 88% of users abandon apps with frequent bugs, and the average data breach costs $4.45 M. The right development partner will build a scalable, secure app and provide ongoing maintenance to safeguard your investment.

questions to ask app developers

Hiring a mobile app developer is a pivotal decision that can make or break your project. The mobile app landscape is extremely competitive – there are millions of apps available, yet only a tiny fraction become successful. In fact, one analysis found that 99.5% of consumer mobile apps ultimately fail to make a lasting impact. To avoid joining those statistics, businesses must choose their development partner carefully. Whether you’re considering a freelance developer or a mobile app development agency, asking the right questions upfront will help you vet candidates and find a partner who can turn your app idea into a success.

A great developer (or development team) doesn’t just write code; they guide you through planning, design, development, and beyond. From defining requirements and designing a stellar UI/UX to ensuring quality, security, and scalability, a lot goes into a successful app. How do you tell if a developer is up to the task? By posing smart, revealing questions and paying close attention to the answers. Below, we outline 10 key questions every business should ask before hiring a mobile app developer, along with why each question matters, what to listen for in a good answer, and how it connects to your app’s success.

Let’s dive into the essential questions and what they reveal:

1. What Is Your Experience in Mobile App Development?

Why it’s important: A developer’s experience and expertise set the foundation for your project’s success. Mobile app development has unique challenges – from keeping up with iOS and Android updates to optimizing for various devices and ensuring a smooth user experience. You want someone who has been through this before. Experienced developers are familiar with common pitfalls and best practices, which helps them avoid costly mistakes. With 78% of mobile apps failing to make a lasting impact, a seasoned developer who has navigated multiple projects is more likely to deliver an app that stands out.

What to look for in their answer: Pay attention to the breadth and depth of their experience. How many years have they been developing mobile apps, and how many projects have they completed? Have they built apps similar to yours in terms of functionality or industry? For example, if you need a healthcare app, does the developer understand compliance requirements like HIPAA and have they delivered mHealth applications before? If your project is a fintech app, have they worked with financial data and security? An ideal answer might mention specific technologies (e.g. Swift/Objective-C for iOS, Kotlin/Java for Android, or cross-platform tools like Flutter/React Native) and notable projects or apps they’ve worked on. Don’t hesitate to ask for details – a confident developer can discuss past projects, challenges overcome, and how those experiences will benefit your project.

Relation to your app’s success: A developer with a solid track record instills confidence that they can execute your vision. They are more likely to deliver on time and handle scope changes gracefully because they’ve done it before. Moreover, experienced teams often bring valuable insights – they can suggest what works and what doesn’t, potentially saving you from pursuing a dead-end approach. In short, proven experience is a strong predictor of reliability and quality. If a candidate struggles to demonstrate any real app development experience or success stories, that’s a red flag to consider other options.

2. Can You Show Examples of Your Previous Work (Portfolio)?

Why it’s important: A portfolio of past work is tangible evidence of a developer’s skills and style. It’s one thing to talk about experience, but seeing actual apps they’ve built (or at least screenshots and case studies) lets you evaluate their quality of work. By reviewing their previous apps, you can gauge the user interface design, the smoothness of the user experience, and even check app store ratings or testimonials. This is crucial because an app that isn’t user-friendly or polished will struggle to retain users – for instance, research shows 71% of users abandon an app within three months if it doesn’t meet their needs. A strong portfolio indicates the developer can create an app that attracts and satisfies users.

app developerWhat to look for in their answer: A good developer should readily provide examples of past apps or projects. Look for diversity and relevance: If they have built apps similar to what you need (in features or industry), that’s a big plus. Ask for links to apps on the App Store or Google Play if available, so you can try them out yourself. When examining their work, consider: Are the apps stable and fast? Is the design modern and appealing? How are the user reviews? Additionally, consider client references or case studies – can they point you to client testimonials or success stories? For example, an agency might have a portfolio page showcasing projects for healthcare, finance, IoT, etc., which demonstrates experience across domains. If a developer is reluctant to share any previous work, or if all their past apps were poorly reviewed, take caution. Transparency here is key; reputable developers are proud to show what they’ve done.

Relation to your app’s success: By seeing what the developer has accomplished before, you get insight into what they can likely do for you. A portfolio that highlights high-quality, successful apps suggests your project is in capable hands. It can also spur important discussions – you might find features or design elements in their past work that you do (or don’t) want in your app. Ultimately, reviewing previous work helps ensure you hire someone whose capabilities and aesthetic align with your vision. It’s also an opportunity to verify their claims: if they say they built a complex e-commerce app, the proof should be visible in their portfolio. This due diligence helps you avoid ending up with a developer who overpromised and underdelivered.

3. What Is Your Development Process?

Why it’s important: The development process a developer or team follows can tell you a lot about how organized, thorough, and reliable they are. Mobile app development isn’t just writing code – it involves planning, design, coding, testing, and iteration. A well-defined process (often following methodologies like Agile or Scrum) greatly increases the chance of a successful outcome. If a developer dives straight into coding without proper planning, it can spell trouble down the line. In fact, poor upfront planning and unclear requirements are top causes of project failure – one report found inadequate requirements gathering to be the leading cause in 39% of failed projects. On the other hand, investing time in a structured discovery phase at the start can “greatly reduce costly mid-project changes and overruns”, as one study noted. Essentially, you want a developer who will map out the journey before starting the drive.

What to look for in their answer: A strong answer will outline the step-by-step process the developer uses. It might sound something like: “First, we conduct a discovery or kickoff workshop to clarify requirements and success metrics. Then we move into wireframing and UI/UX design (to visualize the app’s look and flow), followed by an iterative development phase with regular milestones. We do thorough quality assurance (QA) testing after each iteration. Finally, we handle deployment to the app stores and post-launch monitoring.” The specifics can vary, but key elements to listen for include: requirements gathering, design prototyping, a clear development methodology (e.g. two-week sprints), testing procedures, and deployment. Also, ask how they handle changes or scope creep – do they accommodate changes through a change management process or additional sprints? A developer who mentions an initial discovery phase or planning stage is promising, since “upfront discovery clarifies goals and prevents confusion, rework, and budget blowouts”. If the answer is vague like “We just start coding and figure things out as we go,” that’s a red flag. A well-defined process means fewer surprises for you and a more predictable path to completion.

Relation to your app’s success: Process directly impacts outcomes. A developer with a solid process is more likely to deliver on time and on budget because they’ve accounted for the necessary steps. For example, taking time to finalize requirements and create a prototype can catch issues early, when they’re easier (and cheaper) to fix. Skipping these steps often leads to mid-project setbacks or misunderstandings that cause delays. Moreover, a clear process usually comes with milestones and progress checkpoints, which will keep you in the loop throughout development. This translates to better transparency and trust. Remember, only 16.2% of software projects are completed on time and within budget – those that succeed typically have excellent planning and project management. By ensuring your developer follows a rigorous process (and isn’t just “winging it”), you significantly improve the chances that your app will be completed efficiently and meet your expectations.

4. How Do You Handle Project Management and Communication?

Why it’s important: Building a mobile app is a collaborative effort – even if you’re hiring an external developer or team, you as the client will need to be involved in feedback, decisions, and updates. That’s why effective project management and communication are paramount. Many software projects run into trouble not because of technical issues, but due to misunderstandings, lack of updates, or misaligned expectations. In fact, 57% of failing projects cite communication breakdowns as a major factor. You want to know how the developer plans to keep the project on track and keep you informed. Good communication ensures that issues are flagged early, progress is transparent, and the final product aligns with your goals.

What to look for in their answer: A competent developer or agency will describe a clear communication plan. Look for mentions of regular check-ins or meetings (weekly video calls, sprint reviews, etc.), and the tools they use (e.g. Slack or Teams for chat, Jira or Trello for task tracking, etc.). They might say, “We use Agile methodology – a project manager will send you a progress update at least once a week, and we’ll have review meetings at the end of each sprint. We track tasks in Jira so you can see development progress in real-time. For day-to-day questions or clarifications, we’re available via email or Slack.” It’s also good if they mention how they handle feedback and revisions – for instance, incorporating your input at each milestone. Another thing to listen for is whether they have a dedicated project manager (in a team setting) or if the developer themselves coordinates the timeline and communications. Either can work, but the key is that someone is clearly in charge of organizing the work. If the developer is vague about when or how they’ll talk to you (“just trust us, we’ll get it done”), that’s concerning. In contrast, a developer who emphasizes transparency and even encourages your involvement (e.g. inviting you to planning sessions or test builds) likely values partnership and will be easier to work with. Remember, “constant client communication is a focal point” of effective app development teams – you should feel assured that you won’t be left in the dark.

Relation to your app’s success: Strong project management and communication help ensure the project stays on schedule and aligned with your vision. It allows for agility; if something needs to change, a communicative developer will discuss it with you and adjust the plan (rather than delivering something you didn’t want because “you never asked”). Moreover, regular updates give you visibility into progress and any challenges that arise, so there are fewer last-minute surprises. This is especially critical if you have non-negotiable deadlines (like a launch event or investor demo). Knowing how the developer handles timelines, manages their team (if any), and mitigates risks will give you peace of mind. Essentially, you’re looking for a partner who treats your project with professionalism – that means proper planning, documentation, and open lines of communication. These qualities greatly increase the likelihood that your app will be developed smoothly and will meet your requirements. Poor communication, on the other hand, can lead to mistakes, duplicated effort, or features that don’t hit the mark, all of which jeopardize your app’s success.

5. Can You Provide a Timeline for the Project?

Why it’s important: Time is money in business, and you likely have a target launch date or window in mind. Asking for a timeline forces the developer to think through the project scope and set expectations for how long each phase will take. It’s a test of their planning ability and honesty. An accurate timeline is crucial for your own planning (marketing, stakeholder demos, etc.), and it’s also a benchmark to hold the developer accountable. Projects without a clear timeline often drift or suffer from scope creep. Moreover, many projects run late – having a frank discussion about timeline helps you gauge if the developer is realistic or overly optimistic. Consider that according to industry stats, well over half of software projects exceed their schedules and only 16% finish on time and on budget. So this question isn’t just about getting a number; it’s about understanding how the developer sets milestones and deals with delays.

app developer questionsWhat to look for in their answer: A good developer will usually respond with an estimated timeline broken into phases. For example, “Phase 1 (Discovery & Design): 3-4 weeks; Phase 2 (MVP development): 8 weeks; Phase 3 (Testing and Refinement): 3 weeks; Deployment: 1 week. So overall, we’re looking at roughly 3 months for version 1.0.” They should mention that this is an estimate and may depend on when you provide feedback or content, etc. Importantly, they might describe how they arrived at that timeline – e.g., based on similar projects they’ve done or a rough breakdown of features. If your app has some especially complex components (say, a custom AI algorithm or a hardware integration), ask if those could affect the schedule. Look for signs of realism: if a candidate promises a very short timeline that seems too good to be true (e.g. “Sure, we can build your sophisticated app in two weeks”), they may be underestimating the work or telling you what they think you want to hear. On the flip side, if the timeline is extremely long with no clear reason, that could indicate inefficiency. An ideal answer will also include some buffer or acknowledge potential risks and dependencies (for example, “App store approval can take up to a week or two, which I’ve included in the timeline”). Ultimately, you want to see that the developer has a structured plan and isn’t just guessing arbitrarily.

Relation to your app’s success: A well-defined timeline with milestones is like a roadmap for your project. It helps keep everyone accountable and allows you to track progress. This way, if a phase is slipping behind, you can address it early – not find out at the very end that you’re a month delayed. Timelines also facilitate coordination with other business activities: for instance, you might plan marketing around the expected launch date, or line up beta users for testing at a certain time. If the developer can’t provide a clear timeline, that’s a warning sign of possible disorganization or lack of experience with projects of your scale. Moreover, discussing the timeline can reveal how the developer handles pressure and deadlines. Do they pad their estimates responsibly (underpromise and overdeliver), or do they seem to promise the moon without a plan to back it up? In the long run, an achievable timeline that is met builds trust and momentum, whereas a missed or continually changing timeline can derail the project’s momentum and strain the relationship. In summary, mutual understanding of the development timeline is key to delivering your app on schedule and keeping your business plans on track.

6. What Are Your Charges, and How Do You Structure Your Payments?

Why it’s important: Budget is a critical factor in any project. Beyond just the dollar amount, the payment structure (hourly vs. fixed, milestones vs. lump sum, etc.) can significantly impact cash flow and risk. You need to ensure the developer’s fee fits within your budget and that you’re comfortable with how and when payments will be made. Discussing this upfront helps avoid unpleasant surprises or disputes later. It’s also a chance to clarify what is included in the cost – for example, does the quote cover design, testing, and post-launch support, or are those extra? Transparency here is crucial because money disagreements can sour a working relationship quickly. From an industry perspective, it’s known that nearly half of software projects run over budget (often due to unforeseen changes), so having a clear financial agreement and understanding how changes will be handled is part of protecting your investment.

What to look for in their answer: A professional developer will be open and precise about their pricing model. Common structures include: hourly rates, fixed project price, or a hybrid (e.g. fixed price for an initial scope, then hourly for changes or new features). They might say something like, “Our rate is $X/hour, and we estimate the project at roughly Y hours (~$Z total). We bill bi-weekly and provide time reports.” Or for a fixed price: “We can deliver the app for a fixed $Z cost, which includes 1 month of post-launch support. Payments would be split into three milestones: 30% upfront, 40% on design/prototype completion, and 30% on final app delivery.” There’s no one “correct” answer, but it should be clear when payments are due and what triggers a payment (time, deliverables, etc.). Also, ask about policies for scope changes or additional work: if you decide to add a feature mid-project, how will they charge for it? It’s a good sign if the developer proactively brings up a change control process or says “any work outside the agreed scope will be discussed and estimated separately so you’re always informed.” Be wary of answers that are very vague or push all discussion of cost off (“We can figure it out later” or “It’ll depend, but let’s start first”) – you need at least a ballpark and a model to make an informed hiring decision. Also, if you’re talking to a freelance developer from another country or an offshore team, clarify the currency, and method of payment, and note any taxes or fees. The key is that you feel you understand the financial commitment and that the developer’s terms are fair and professional.

Relation to your app’s success: Financial clarity contributes to project stability. When both parties agree on payment terms, it builds trust and lets you focus on the work rather than worrying about money issues. By knowing the cost breakdown, you can also manage your own budget and ROI expectations. For instance, if the developer charges extra for additional features, you might prioritize which features are truly essential for the first release. Additionally, the payment structure can serve as a form of accountability: milestone-based payments ensure the developer has incentive to hit deliverables, while time-and-materials (hourly) arrangements require you to monitor progress but offer flexibility if you change direction. There’s also the question of value – a very cheap quote might be tempting, but it could indicate inexperience or corners cut (remember the old adage, “you get what you pay for”). Conversely, a higher upfront cost might come with more inclusive services (like strategy, design, maintenance) that could save you money long-term. Ultimately, open discussion about cost and pricing structure is part of hiring the right developer as a long-term partner. It ensures you’re on the same page and can proceed with confidence that the project is financially viable, reducing the risk of conflicts or project abandonment due to budget issues.

7. Will You Provide Post-Launch Support and Maintenance?

Why it’s important: Launching your app is not the end of the journey – it’s the beginning of your app’s life in the hands of users. Post-launch, you’ll likely need to address user feedback, fix bugs that escaped initial testing, release updates for improvements, and adapt to OS updates or new devices. Ongoing maintenance is crucial to keep the app relevant and functional. If a developer vanishes right after delivering the first version, you could be left scrambling to find someone else to handle issues or improvements. Additionally, consider that nearly a quarter of mobile apps are uninstalled by users within just one day of download, and about 49% within a month – often due to bugs or lack of ongoing value. This shows how important it is to refine and improve your app quickly post-launch. Ensuring the developer offers support means you can react swiftly to any problems or opportunities that arise once real users start interacting with your app.

What to look for in their answer: The developer should outline what kind of post-launch services they offer. Good signs include: “We include X months of free bug-fixing support after launch,” or “We offer maintenance packages or can work on an as-needed basis for updates.” They might mention services like monitoring performance, analytics reviews, or assistance with app store updates. Some agencies have formal maintenance contracts (for example, a monthly retainer that covers a certain number of hours of updates or on-call support). Others might do it ad hoc. Either way, get clarity. Important questions to cover: How do they handle bug fixes discovered after launch – is that included in the original cost or billed separately? Will they help with minor enhancements or version upgrades down the line? Also, ask about app store support: if Apple or Google requires changes or if there’s an OS update (like a new iOS version), will the developer help update the app to maintain compatibility? An ideal answer gives you confidence that the developer won’t consider their job “done” the moment the app is released. If instead you hear something like, “Once it’s launched, our contract is done; any further work is on you,” then you need to be prepared to either negotiate a support agreement or arrange your own team to take over maintenance. It’s not necessarily a deal-breaker if a freelance developer doesn’t include long-term support, but you must have a plan for who will maintain the app. It’s certainly a plus if the person you’re hiring is willing to stick around and help your app succeed over time.

Relation to your app’s success: The period after launch is critical. Users today have high expectations and plenty of alternatives – if they encounter a lot of bugs or see no improvements, they’ll abandon your app (and maybe leave negative reviews that deter others). A smooth, well-supported app will fare much better. Post-launch support ensures you can quickly squash any bugs that slipped through and continually refine the user experience, which can turn an average launch into a successful product with growing user engagement. Furthermore, business needs often evolve: you might want new features as your user base grows or pivot based on user behavior. Having a developer who knows your app’s codebase and is available to implement updates will save you the trouble of onboarding someone new each time. It’s also worth noting that both Apple and Google frequently update their mobile operating systems (usually annually, with iOS and Android major releases). These updates can sometimes introduce compatibility issues or new standards for apps. Without maintenance, your app could gradually break or feel outdated. In summary, asking about post-launch support is about securing the long-term health and competitiveness of your app. A developer committed to your app’s lifecycle – not just its initial build – is a valuable partner in ensuring your mobile app continues to satisfy users and meet your business goals well into the future.

8. How Do You Ensure the Security of the App?

Why it’s important: Mobile apps often handle sensitive data – whether it’s personal user information, financial transactions, or proprietary business data. A security lapse can lead to data breaches, ruined user trust, and hefty legal or compliance penalties (especially if your app deals with regulated data like health or finance). In today’s environment, cybersecurity is a paramount concern for any software product. The average cost of a data breach in 2023 reached an all-time high of $4.45 million, which underscores how devastating a security failure can be. Even beyond direct costs, think about the reputational damage – users are unlikely to return to an app (or company) that exposed their data. Thus, you need a developer who takes security seriously from day one, baking in protective measures rather than treating it as an afterthought.

What to look for in their answer: The answer should demonstrate that the developer is knowledgeable about secure coding practices and risk mitigation. Concretely, look for mentions of things like: encryption of data (both in transit and at rest), using secure protocols for network communication (HTTPS, SSL/TLS), proper authentication and authorization methods (for example, OAuth 2.0, JWTs for session management, etc.), and defense against common mobile app vulnerabilities (like the OWASP Top 10 for mobile, which covers issues such as insecure data storage, weak server-side controls, etc.). They might also mention code review and testing focused on security, such as penetration testing or using tools to scan for vulnerabilities. If your app will involve sensitive info, ask if they are familiar with relevant compliance standards – e.g., HIPAA for health data, PCI DSS for credit card information, GDPR for user privacy in the EU, etc. A reassuring answer could be: “We follow best practices like using SSL for all API calls, encrypting any personal data stored on the device, and never hard-coding sensitive keys. We also implement secure user authentication (e.g. OAuth tokens) and run penetration tests before launch. If we’re building a healthcare app, we ensure HIPAA compliance in how data is handled.” You want specifics that show they have a security mindset. On the other hand, if someone says, “Oh, mobile apps are generally safe, we don’t do anything special for security,” consider that a red flag – it indicates they might not be up-to-date or concerned about protecting user data. Given that 81% of hacking-related breaches are due to weak or stolen passwords (a stat from a security study), for example, a developer should at least speak to how they’ll handle user credentials safely (like using salted hashing for passwords, offering two-factor authentication, etc.).

Relation to your app’s success: Trust is everything. If users (or your business partners) can’t trust your app to keep data secure, they won’t use it – as simple as that. Many successful apps highlight their security measures as a selling point. By ensuring your developer prioritizes security, you’re investing in the app’s longevity and integrity. From a business perspective, avoiding a breach saves you potentially catastrophic costs and setbacks. It’s also far easier (and cheaper) to build security in from the beginning than to retrofit it after an incident. Additionally, app store guidelines and review processes increasingly scrutinize apps for proper handling of user data. A sloppy approach to security might even get your app rejected or flagged. In sectors like fintech or healthtech, security isn’t just a nice-to-have; it’s non-negotiable. Remember that a single high-profile security failure can undermine months or years of hard work building your app’s reputation. Conversely, robust security and privacy practices will enhance user confidence and could even be a competitive advantage. In summary, by asking this question, you’re ensuring that your developer will guard your users and your business against threats – a cornerstone for your app’s success and credibility.

9. Will the App Be Scalable to Accommodate Future Growth?

Why it’s important: You’re likely hoping your user base will grow and that you might add more features over time. Scalability refers to the app’s ability to handle increasing numbers of users, data, and transactions without a decline in performance, as well as the ease of extending the app’s functionality down the line. If an app is built without regard to scalability, it might work fine initially but then crumble under the weight of success – slow down, crash often, or become very costly to modify. Many apps that gain sudden popularity face this challenge. Planning for scalability from the start can save you from having to do a painful (and expensive) rewrite or infrastructure overhaul later. In fact, a common reason apps fail after launch is that they struggle to handle increased user demand – they weren’t architected for growth and thus frustrate users with crashes or poor performance. Asking this question encourages the developer to explain how they design for the long term, not just the immediate needs.

What to look for in their answer: The developer should talk about technical approaches and architecture decisions that enable scaling. For instance: “We build apps with a modular architecture and use scalable backend services. If we expect the user base to grow, we might use cloud infrastructure (like AWS, Google Cloud, or Azure) that can auto-scale as needed. We also design the database with indexing and normalization (or use a scalable NoSQL store if appropriate) to handle large data volumes.” They might mention specific strategies like load balancing (to distribute traffic), caching (to improve response times under load), and separating concerns via microservices or APIs (so that parts of the system can scale independently). For front-end scalability (the app itself), it’s often about coding efficiently and using the right patterns so the app runs smoothly even as more data or content is loaded. If your app has real-time features or heavy multimedia usage, ask how they’ll ensure performance when many users are on simultaneously. It’s also good if they address scalability of adding features: for example, “We write clean, well-documented code so future developers (or we) can extend it. We follow MVC/MVVM patterns that make it easier to add functionality without breaking existing ones.” An excellent answer might include an anecdote like, “In a past project, we built the app to scale from 1,000 to 100,000 users by doing X, Y, Z, and indeed when the user base grew, the app handled it by scaling the servers and optimizing queries.” Essentially, they should show foresight. If a developer seems puzzled by the concept or says “We’ll worry about that when we get there,” that’s concerning – it could mean they aren’t building with best practices that ensure stability at scale.

Relation to your app’s success: Scalability is about future-proofing your investment. If your app succeeds, you don’t want it to become a victim of its own popularity. Users can be unforgiving with slow or unreliable apps – they’ll quickly switch to a competitor if your app can’t serve them promptly. By ensuring scalability, you maintain a good user experience even as demand grows. This also affects your business strategy: maybe today you only need an app for one city or one use case, but in a year you might want to expand to many regions or add new features/modules. A scalable codebase and backend will make those expansions much faster and cheaper, whereas an unscalable one could force you to start from scratch. Moreover, investors or stakeholders will often inquire about your tech scalability if you’re a startup – being able to say your app is built on robust, scalable technology instills confidence. It’s the difference between your app hitting a ceiling and stalling out versus continuing to grow with your user base and market opportunity. In short, by confirming that your developer plans for scalability, you’re aligning your app with your long-term business growth goals and avoiding a scenario where your success becomes a headache instead of a celebration.

10. What Technologies and Tools Do You Use for Development?

Why it’s important: The technology stack and tools a developer uses will directly impact your app’s performance, maintainability, and compatibility. This question serves multiple purposes. First, it ensures the developer’s expertise aligns with your project’s needs (for example, if you need an iOS app, do they use Swift or Objective-C? If cross-platform, are they proficient in Flutter or React Native?). Second, it reveals whether they stay current with industry standards – using outdated or niche technologies might pose a risk for future support and hiring additional developers. Third, it can give insight into their development efficiency and quality (e.g., do they use modern frameworks and libraries, version control systems, CI/CD for continuous integration, etc.). In an industry where tools and frameworks evolve quickly, a developer who uses the right technologies will likely build a better product faster. According to surveys, many companies struggle to hire developers with certain up-to-date skills, so knowing the developer’s toolset helps ensure they’re using widely-adopted tech (which is easier to find talent for if needed later).

What to look for in their answer: Listen for specifics. A competent developer might say, “For iOS development I use Swift and Xcode, for Android I use Kotlin (or Java) with Android Studio. I manage code with Git (using platforms like GitHub or GitLab) for version control. For cross-platform projects, I have experience with React Native and Flutter. I also use libraries like Alamofire for networking on iOS, or Retrofit on Android, to ensure robust network calls, and perhaps Firebase for backend services when appropriate.” They should also mention how they handle things like bug tracking and project management tools (e.g., Jira, Trello) and testing frameworks (like XCTest for iOS, Espresso for Android, etc., or cross-platform testing tools). If your app requires a particular technology (say, a machine learning component, GPS/location services, ARKit for augmented reality on iOS, etc.), verify they are familiar with it. It’s a good sign if the developer explains why they choose certain technologies: for example, “We prefer Flutter for simple multi-platform apps to speed up development, but if performance needs are very high or platform-specific features are crucial, we’d go native.” This shows thoughtful decision-making. Also, inquire if they anticipate any part of the tech stack needing special licenses or ongoing costs (sometimes using certain third-party services has fees, which you should know about). If a developer’s answer is very superficial or if they seem unfamiliar with common tools (for instance, not using any version control is almost unthinkable in professional development), that’s a red flag. A strong answer demonstrates not just familiarity but enthusiasm for using the best tools for the job – it shows they take pride in their craft and are set up to deliver a high-quality app.

Relation to your app’s success: The technologies used will affect everything from the app’s user experience to how easy it is to update or fix issues in the future. By understanding the stack, you also future-proof yourself: if down the line you need to hire another developer or team (even just to augment or take over the project), it’s much easier if the app is built with popular, well-documented technologies. For example, an app written in Swift/Kotlin or built with React Native will have a large community and talent pool; an app written in an obscure language or outdated framework might leave you stranded if the original developer isn’t available. Tools like version control and continuous integration mean fewer mistakes and faster delivery because they enable collaborative development and automated testing/deployment. In essence, a modern tech stack and toolchain contribute to a more reliable, scalable, and maintainable app, which is critical for long-term success. Additionally, certain tools can improve development speed, which means you get to market faster and can iterate more quickly on user feedback. This question also signals to the developer that you care about how the sausage is made, not just the end result – which can encourage them to maintain high coding standards. All in all, verifying the tech and tools helps ensure you’re hiring a developer whose workflow is efficient and whose technology choices will set your app up for success, not technical debt.

After covering these ten questions, you’ll have a much clearer picture of which app developer or agency is the right fit for your business. The goal is to find a partner who is technically competent, communicative, security-conscious, and aligned with your vision. By asking about everything from their experience and process to post-launch support, you’re doing proper due diligence to avoid common pitfalls. Remember, developing a mobile app is not just a one-time transaction but often the start of an ongoing relationship – choosing the right developer can pave the way for a smooth development journey and a successful app that delights your users.

Now that we’ve outlined the key questions to ask, let’s address a few frequently asked questions (FAQ) that businesses often have when approaching the process of hiring a mobile app developer:

FAQ: Hiring a Mobile App Developer

Q: Is it better to hire a freelance app developer or go with an app development agency?

A: It depends on your project’s scope, budget, and desired level of support. Freelance developers can be cost-effective and are suitable for smaller projects or prototypes. Working with a freelancer often means you’ll communicate directly with the person doing the work, which can be efficient, but a single individual might have limitations in skill set or bandwidth. Agencies, on the other hand, bring a full team (developers, designers, project managers, QA testers, etc.) which is ideal for larger or more complex projects.

An agency like Dogtown Media can offer a breadth of expertise and resources; they often have established processes and can handle everything from strategy and design to development and deployment. The trade-off is usually higher cost compared to a solo freelancer. Additionally, agencies provide continuity – if one team member becomes unavailable, they have others to fill in, whereas with a freelancer, the project could stall if they have an emergency or overbooked schedule. In short, for a mission-critical app where you need a range of expertise and ongoing support, an agency might be the safer bet. For a smaller, well-defined app (or if you already have in-house talent to cover some roles), a freelancer could be sufficient. Always vet either type thoroughly: there are excellent freelancers and excellent agencies, just as there are less reliable ones of both types.

Q: How can I protect my app idea when discussing it with potential developers?

A: It’s natural to be cautious about sharing a novel app idea. The common approach is to use a Non-Disclosure Agreement (NDA). Before you divulge the details of your concept, you can ask the developer or agency to sign an NDA, which is a legal document preventing them from sharing or using your idea without permission. Reputable developers are very used to this and will not be offended – many will offer to sign an NDA early in discussions. Keep in mind, NDAs offer reasonable legal protection, but the reality in the industry is that ideas are rarely “stolen” by professional developers (they have their own projects and reputations to consider).

Execution is the hard part, and that’s what you’re hiring them for. Nonetheless, you should own the intellectual property (IP) for the work done. So ensure that your contract specifies that all code, designs, and materials produced for the project will be your property once payment is made. This way, after the project, you’re free to use, modify, or even bring another team in to work on the app without complications. If the developer is providing some proprietary libraries or components, clarify how those can be used. In summary: use an NDA during initial talks, have a clear contract stating IP ownership, and you can feel much safer sharing your vision.

Q: I’m not very tech-savvy. How can I effectively evaluate a developer’s answers to these questions?

A: You don’t need to be a programmer to hire a good one, but you do need to do a bit of homework. When you ask the questions we’ve outlined, focus on the clarity and confidence of the answers. A good developer should be able to explain their process and technical choices in layman’s terms or at least in a way that makes sense. If you find their answers confusing or full of unexplained jargon, that could be a communication issue (which could surface later in the project). Don’t be afraid to ask follow-ups like “What does that term mean?” – part of a developer’s job, especially an agency’s job, is to educate and guide clients. You can also request to speak with some of their previous clients.

Hearing another business owner’s perspective about how the project went can be incredibly insightful. Additionally, consider involving a technically savvy friend or advisor in the interview process. If you have someone you trust who has experience with software development, they can help assess the more technical parts of the discussion. Lastly, rely on common business sense: evaluate their professionalism, responsiveness, and whether they ask you smart questions. A developer who tries to understand your business goals and target audience (rather than just saying “yes” to everything) is likely going to be a more trustworthy partner. Remember, you’re looking for someone who not only has the technical chops but also communicates well and understands the bigger picture of your project’s success.

Q: How much input will I need to provide during development?

A: Expect to be involved, especially at key stages. In the early phase, you’ll need to clearly communicate your requirements, goals, and preferences – what features the app must have, how you envision it to look, who the end-users are, etc. During design, your feedback will shape the UI/UX; you might be shown wireframes or mockups and asked to approve or suggest changes. Throughout development, particularly if an Agile process is used, you might be asked to review interim builds or participate in sprint demos. It’s important to test these builds from a user perspective and give constructive feedback. As the client, you also have the role of decision-maker: when trade-offs arise (e.g., cutting a feature to meet a deadline), your input will guide the priorities.

Finally, for launch, you’ll likely need to set up developer accounts on app stores (the developer can help, but the account might be in your company’s name), and prepare things like app descriptions, marketing materials, etc. While the developer handles the heavy lifting technically, your domain knowledge and vision steer the project. That said, a good development partner will make this process as smooth as possible – they’ll ask the right questions to extract the info they need and won’t overwhelm you with technical minutiae. Many businesses find it useful to designate a point person (if not yourself) who interfaces with the developers regularly. In summary, plan to collaborate closely; the more engaged and responsive you are (e.g., providing feedback in a timely manner), the more efficiently the project will run. Think of it as a joint effort: they know how to build apps, and you know your business – the app will succeed by combining those strengths.

Q: What if the first version of the app isn’t exactly what I wanted?

A: It’s not uncommon for the initial version (often called an MVP – Minimum Viable Product) to need tweaks and improvements. This is why an iterative process is valuable. Ideally, if you’ve maintained good communication and provided feedback throughout, there shouldn’t be major surprises at the end. However, once you see the fully working product, you might realize some things aren’t as you envisioned or new ideas pop up. The first step is to distinguish between bugs (things that don’t work as intended or differ from agreed requirements) and change requests or new features. Any reputable developer will fix bugs – those are errors – typically as part of the project scope or warranty. For changes that are essentially new scope (e.g., “I know we said blue for the branding, but now we want to integrate with Facebook Login”), you’ll need to discuss those as Phase 2 or as additional work.

This is where having that post-launch support agreement or ongoing relationship helps. A good developer will take your feedback, help you prioritize which changes are critical, and then plan an update release. Keep in mind user feedback will also guide these updates; often the app owner’s perspective changes once real users weigh in. It’s wise to budget some time and money for a post-launch improvement cycle. This might involve a quick follow-up project to refine the app. Ultimately, building a successful app is an evolving process – launch is a milestone, not the finish line. By setting the expectation that the first version can be improved (and choosing a developer who embraces continuous improvement), you won’t be disappointed. Instead, you’ll view it as gathering real-world insight to make the app even better. Many top apps went through several iterations before finding the perfect product-market fit, so think long-term. The key is to work with a developer who is committed to your satisfaction and success, not one who disappears after delivering “version 1” regardless of quality.

By asking these ten crucial questions and heeding the answers, you’ll be well-equipped to choose a mobile app developer who is capable, reliable, and aligned with your business needs. The right hire will not only write good code but will also be a partner in bringing your app vision to life – helping you navigate technical decisions, avoid pitfalls, and ultimately deliver an app that can thrive in the competitive mobile market. Remember that successful app development is a collaboration between you and your development team, and it all starts with finding the best people for the job. Good luck with your mobile app project!
