Mobile Accessibility Testing
Mobile accessibility testing verifies that a mobile app is usable by people with disabilities — screen reader compatibility (VoiceOver on iOS, TalkBack on Android), sufficient touch target sizes, color contrast, and support for platform accessibility settings like larger text.
Mobile platforms have their own accessibility APIs and conventions distinct from web WCAG guidelines — testing needs to specifically confirm screen reader users can navigate using platform-native gestures (swipe to move between elements, double-tap to activate), that touch targets meet minimum size guidelines (roughly 44x44 points on iOS, 48x48dp on Android), and that the app respects system-level accessibility settings rather than overriding them.
Both Apple and Google provide built-in accessibility auditing tools (Accessibility Inspector on iOS, Accessibility Scanner on Android) that catch common issues automatically, though — as with web accessibility — manual testing with an actual screen reader remains necessary to catch issues automated scanning misses.
