Mobile Accessibility Audit Framework
Audit mobile UI designs for WCAG compliance and generate remediation strategies
What You Can Do
You can conduct comprehensive accessibility audits of mobile UI designs and prototypes by leveraging Claude's contextual evaluation against WCAG 2.1 standards. The framework identifies nuanced accessibility issues that automated tools miss—from touch target sizing and color contrast to keyboard navigation and screen reader compatibility—and generates actionable remediation strategies tailored to your specific mobile context with implementation guidance.
Features
ensures buttons and interactive elements meet minimum 44×44dp tap requirements for mobile accessibility
evaluates visual hierarchy and contrast ratios for readability across different lighting conditions and vision types
reviews font sizes, line spacing, and text density for comfortable mobile consumption
identifies navigation flow issues and focus state visibility for non-touch users
assesses semantic structure, labeling, and announcements for assistive technology users
flags potentially problematic animations and identifies prefers-reduced-motion alternatives
ensures complex gestures have discoverable, accessible alternatives for users with motor difficulties
evaluates error handling, field labeling, validation messaging, and input accessibility
Example Output
Example 1: Touch Target Audit
Issue: Login button is 32×32dp
Severity: High
WCAG Criterion: 2.1.1 Keyboard, 2.5.5 Target Size
Recommendation: Increase to minimum 44×44dp with appropriate padding. Code:
<TouchableOpacity style={{minWidth: 44, minHeight: 44, padding: 12}}>
<Text>Login</Text>
</TouchableOpacity>
Example 2: Color Contrast Finding
Issue: Secondary button text (#777777) on light gray background (#EEEEEE) = 3.2:1 ratio
Severity: Medium
WCAG Criterion: 1.4.3 Contrast (Minimum)
Recommendation: Increase to 4.5:1 for AA compliance. Change text to #555555 or background to #F5F5F5.
Example 3: Prioritized Remediation Plan
- Critical (fix immediately): Form labels missing for screen readers
- High (sprint planning): Color contrast below 4.5:1 on primary CTA
- Medium (next release): Swipe gestures lack keyboard alternatives
- Low (design system update): Icon-only buttons need visible labels
