For many users, their mobile device is an indispensable companion that accompanies them throughout the day. However, for over a billion people worldwide living with disabilities, using their favorite apps can be a frustrating and isolating experience. This isn't just a matter of accessibility – it's about creating products that truly serve everyone.

The Importance of App User Experience

When we design accessible apps, we create better experiences for everyone. Someone with a temporary impairment, such as a broken arm, faces similar challenges to a person with permanent motor impairments. A user struggling to see their screen in bright sunlight experiences the same visibility issues as someone with visual impairments. By prioritizing app user experience, we can tap into a massive market and drive innovation.

Essential Guidelines for Accessible Mobile Apps

Fortunately, there are two key guidelines that developers can follow to ensure their apps are accessible: the Americans with Disabilities Act (ADA) and Web Content Accessibility Guidelines (WCAG) accessibility standards. The ADA aims to prevent discrimination against individuals with disabilities, while WCAG provides 80 success criteria to help developers create accessible apps.

Designing for App User Experience

To design an app that's truly usable by everyone, follow these best practices:

Visual Accessibility

  • Use strong color contrast ratios between text and backgrounds (at least 4.5:1 for normal text and 3:1 for large text).
  • Allow users to resize text up to 200% without breaking your layout.
  • Ensure consistent navigation and identification by using ordered hierarchies and similar text for buttons with similar functions.

Touch and Interaction Design

  • Use generous tap & touch targets (at least 9mm x 9mm).
  • Stick to basic gestures like taps and simple swipes, avoiding complex gestures that can exclude users with motor impairments.
  • Keep navigation elements in predictable locations to ensure a consistent user experience.

Testing Accessibility

To ensure your app meets WCAG criteria and real-world usability for all users, combine automated tools like Axe and WAVE with manual human testing. This will help you identify and fix accessibility issues before they become major problems.

The Business Case for App User Experience

By prioritizing app user experience, developers can tap into a massive market of over $13 trillion in potential revenue. Additionally, accessible apps can improve brand reputation, future-proof products against evolving regulations, and drive innovation and customer loyalty.

In conclusion, designing accessible mobile apps is not only the right thing to do – it's also good business sense. By following guidelines like WCAG 2.1 and ADA, developers can create apps that truly serve everyone, including those with disabilities.
