Accessibility in Mobile Apps

Accessible apps reach more users and are often required for compliance. For React Native and Expo, a few habits go a long way.

Semantic Labels and Roles

Use accessibilityLabel and accessibilityHint so screen readers describe controls correctly. Prefer built-in roles (accessibilityRole="button", "header", "link") instead of generic containers. Test with VoiceOver (iOS) and TalkBack (Android) on real devices.

Focus Order and Navigation

Ensure focus order follows visual flow. Avoid trapping focus in modals or lists. Support keyboard and switch navigation where applicable. accessibilityViewIsModal and focus management for dialogs matter for users who don’t use touch.

Contrast and Touch Targets

Meet WCAG contrast ratios for text and important UI. Use touch targets of at least 44×44 pt. Avoid relying on color alone to convey information. These choices help users with low vision and motor differences.

Building accessibility in from the start is easier than retrofitting later. One pass per feature keeps your app inclusive and future-proof.
