App Accessibility refers to the design and development of mobile applications to ensure usability for people with disabilities. Key principles include:
- Compatibility with assistive technologies like screen readers (VoiceOver, TalkBack) and switch controls.
- Adaptable UI with adjustable text size, colour contrast, and voice commands.
- Intuitive navigation via keyboard or gesture controls for motor impairments.
- Inclusive content like captions for videos and clear error messages.
Guided by standards like WCAG and platform-specific guidelines (iOS/Android), accessible apps comply with laws such as the ADA and EN 301 549. Benefits extend beyond disabilities, elderly users or those in situational limitations (e.g., bright sunlight) also gain improved usability. Prioritising accessibility expands reach, avoids legal risks, and fosters social responsibility.
