Mobile App Accessible Design

Smartphone usage among people with disabilities may surprise you. According to a 2021 Pew Research Center survey, a full 72% of adults with disabilities own a smartphone. That’s an enormous untapped market that many businesses overlook when developing their mobile apps. 

Accessible design isn’t just about legal compliance–it’s about reaching a wider audience and expanding your potential user base. By building accessibility into your mobile app from the start, you open doors to new customers, sources of revenue, and avenues for growth.

There are both ethical and business reasons for prioritizing accessible design. On the ethical side, ensuring people with disabilities can access your services demonstrates a commitment to inclusivity and social responsibility. From a business perspective, accessible design helps mitigate legal risks, bolsters brand reputation, and builds customer loyalty. 

Recent legal cases have set a precedent–if your app isn’t accessible, you may be vulnerable to lawsuits under the Americans with Disabilities Act (ADA) or other statutes. Making accessibility a priority from the start helps minimize these legal risks.  

More importantly, accessible design has been shown to boost brand image and reputation. By signaling your commitment to inclusivity to your customers, you generate goodwill and trust. It’s also closely tied to customer satisfaction and loyalty. If customers with disabilities can easily use your app, they’re more likely to promote it to friends and family and on social media.

What is Accessible Design?

Mobile app accessibilityAt its core, accessible design means creating mobile apps that work for all users, including those with disabilities. It involves developing intuitive interfaces that can adapt to users’ needs and capabilities.  

Some examples of accessible design features include:

  • Compatibility with screen readers for blind or low vision users 
  • Options to adjust color contrast for improved readability
  • Flexible layouts that can scale text size up or down

The goal is to avoid design choices that could prevent users with disabilities from being able to navigate, understand, and use your app effectively.

WCAG Guidelines

The Web Content Accessibility Guidelines (WCAG) serve as the industry standard for accessible design across the web, mobile apps, and other digital channels. These guidelines outline compliance criteria to make content accessible for those with auditory, visual, mobility, and neurological disabilities. 

By leveraging expertise around the WCAG guidelines, developers can create intuitive interfaces and ensure their apps meet accessibility standards. This level of compliance opens businesses up to new potential users and markets.

The Benefits of Accessible Design (Beyond Compliance)

Expanded User Base

Accessible design dramatically expands an app’s potential user base. Consider popular apps like Uber. By building accessibility features like text-to-speech into its app, Uber managed to tap into an underserved market of customers with visual impairments. The result? Increased ridership and revenue. Accessible design allows companies to connect with customers they may have overlooked.  

Improved User Experience

Accessibility features don’t just benefit users with disabilities–they often improve apps for everyone. For example, video captions are invaluable for users watching videos in noisy environments. Similarly, clear navigation and alt text for images enhances usability across the board. By improving experience for the most vulnerable users, businesses end up boosting usability for all.

Innovation and Problem-Solving

Accessible design requires developers to approach problems in new ways. Designing an intuitive interface that works seamlessly with screen readers or other assistive tools demands creativity and critical thinking. The result is innovative solutions that remove barriers for some users while streamlining functionality for others. Accessibility stretches teams to build better, more thoughtful apps.  

SEO and Discoverability

Research shows accessible websites and apps tend to rank higher in search engines like Google. The optimizations required for accessibility have positive SEO side effects. The easier your content is to crawl, index, and understand, the better it ranks in organic search.

Brand Reputation and Loyalty  

Accessible design demonstrates social responsibility and inclusivity–values increasingly important to consumers. Companies that embrace accessibility signal care for the well-being of diverse customers in their branding and messaging. In turn, this generates brand loyalty among underserved audiences. Accessibility also garners positive PR, boosting reputation in the public eye. The result is a competitive edge rooted in doing good.

Key Elements of Accessible Mobile App Design

Navigation and User Interface

Simple, intuitive navigation is critical for accessible design. Menus and links should be logically organized and clearly labeled so users can easily orient themselves and find desired content. Additionally, all interactive elements should be within reach for voice command, touch screens, and users with limited mobility. This ensures all users can fully operate apps.

Text and Visuals 

When working with text and visuals, developers must follow best practices around fonts, color contrast, and alternative text. Font choices impact readability for those with learning disabilities or visual impairments. Contrast levels determine whether visual-oriented users can comfortably view content. Meanwhile, alternative text (alt text) provides text descriptions of images and media, allowing screen reader users to access non-text elements. Keeping these guidelines in mind removes barriers for users.  

Audio and Multimedia

Any audio or video content should include accompanying captions or transcripts. This allows users with hearing impairments to fully engage with multimedia. Developers must also ensure media players and controls are accessible across input methods like touch screens, keyboards, voice commands, and assistive technologies.

Input and Interaction

Apps should support diverse input methods beyond touch screens. Users should be able to navigate apps using voice commands, external keyboards, screen reader technologies, and other assistive tools. All functions should integrate easily with these technologies. Prioritizing keyboard compatibility and screen reader testing is key.

Implementing Accessible Design in Mobile App Development

Planning and Research

Accessibility cannot be an afterthought. Developers must consider inclusivity from the very first wireframes and prototypes. Early planning and research is critical. Auditing competition, conducting user studies with people with disabilities, and consulting guidelines sets the stage for success. Accessibility must be baked into apps from their inception. 

Tools and Resources

Many tools and resources help developers build and validate accessibility:

  • Accessibility checkers automatically scan for issues and provide reports 
  • Assistive technologies like screen readers offer first-hand user experience
  • W3C’s Web Content Accessibility Guidelines outline compliance standards
  • Libraries like React Accessible Accordion expedite development
  • Successful apps like Aira serve as models for inclusive UX.

Leveraging these resources helps developers efficiently incorporate accessibility features.

Testing and Validation

To guarantee accessibility, continuous testing is a must. Automated audits quickly catch a wide range of issues, while manual testing replicates real user scenarios. Testing assistive tech compatibility is critical. Most importantly, user studies with people who actually rely on accessibility features provides invaluable feedback. This input should inform ongoing iterations to apps in development and post-release. Accessibility requires continual refinement and validation to account for evolving user needs.

Common Accessible Design Mistakes to Avoid

Poor Color Contrast

Sufficient color contrast between foreground and background elements is essential for visually impaired users. For example, light gray text on a white background is very difficult to read. Instead, aim for at least 4.5:1 contrast ratio. 

Unclear Navigation

Navigation should be simple, logical, and labeled clearly so users can easily find their way around an app. Disorganized menus or ambiguous icons quickly confuse users. Keyboard compatibility is also key for those unable to use touchscreens. Ensure all elements are reachable and operable without a mouse.  

Lack of Alternative Text

Any non-text elements require accompanying alt text descriptions. Images, audio files, videos, and graphs mean nothing to blind users without textual context. Leaving these elements unlabeled excludes an entire audience. Craft descriptive alt text tailored to context for full accessibility.

As technology progresses, ensuring digital accessibility will only grow in importance. By taking an inclusivity-first approach now, developers future-proof their apps while becoming industry leaders in this critical space. It’s a win-win—better user experience for all, expanded market share, and positive brand reputation. The time for accessible design is now.
