Why Accessibility Matters in India
India has 26 million visually impaired people and 18 million with hearing impairments — a significant user base that most apps ignore. Beyond ethics, accessible apps rank better on Google (semantic HTML benefits SEO), load faster (clean markup), and convert better across all user segments.
WCAG 2.1 Key Requirements
Four core principles: Perceivable (content visible to all senses), Operable (usable via keyboard/switch), Understandable (clear language and predictable behavior), Robust (compatible with assistive technologies). AA compliance is the standard target for most apps.
Practical Implementation
Start with: minimum 4.5:1 contrast ratio for body text (7:1 for large text), alt text for all images, keyboard navigation for all interactive elements, ARIA labels for icon-only buttons, and captions for videos. Use the axe Chrome extension for automated accessibility testing.
Screen Reader Compatibility
Indian users use TalkBack (Android) and VoiceOver (iOS) with Hindi and regional language support. Test your app with these tools enabled. Common failures: images without alt text, form fields without labels, custom components not accessible via screen readers, and modals that trap keyboard focus.
Business Case for Accessibility
Accessible apps have 20% larger addressable markets, better SEO rankings, lower legal risk, and improved usability for ALL users (elderly users, users with temporary injuries, users in bright sunlight). The cost to retrofit accessibility is 10x higher than building it in from the start.
