Free Mobile Accessibility Test — WCAG 2.1 AA Compliance Check

Mobile Accessibility Checker — Test Your Mobile App or Website Against WCAG 2.1 AA

Welcome to the AccessiTool Mobile Accessibility Checker — your free tool for testing mobile accessibility against WCAG 2.1 Level AA standards. Whether you're a developer, designer, or business owner, our mobile accessibility test helps you ensure your mobile app or website is accessible to people who rely on screen readers, touch targets, and assistive technologies.

With our free mobile accessibility checker, you can instantly scan any mobile website or app for accessibility issues. Just enter a URL above, and our tool will check for touch targets, screen reader support, viewport settings, gesture alternatives, and more. It's that simple.

Why Mobile Accessibility Matters for Compliance

Over 60% of web traffic now comes from mobile devices. Lawsuits citing inaccessible mobile apps have surged, targeting banking apps, e-commerce checkout flows, and restaurant ordering systems. Common mobile violations include small touch targets (under 44x44 pixels), missing screen reader labels, and pinch-to-zoom restrictions.

ADA compliance for mobile apps is required under ADA Title III. Courts have ruled that mobile apps are covered under ADA. ADA mobile compliance is essential for lawsuit protection. ADA mobile app requirements include touch target size, screen reader compatibility, and color contrast.

The European Accessibility Act (EAA) requires mobile apps for e-commerce, banking, transport, and telecom services to be accessible. Non-compliant mobile apps can result in fines up to €100,000.

Common Mobile Accessibility Failures

1. Touch Targets Too Small

Issue: Buttons and links under 44x44 pixels (WCAG 2.5.5).

Fix: Increase click/tap area with padding: min-width: 44px; min-height: 44px; padding: 10px;

2. Zoom Disabled

Issue: user-scalable=no or maximum-scale=1.0 in viewport prevents zooming.

Fix: Remove these from viewport meta tag: <meta name="viewport" content="width=device-width, initial-scale=1">

3. Missing Screen Reader Labels

Issue: Buttons without ARIA labels or content descriptions.

iOS Fix: button.accessibilityLabel = "Close menu"

Android Fix: android:contentDescription="Close menu"

Web Fix: <button aria-label="Close menu">✕</button>

4. Gesture-Only Interactions

Issue: Swipe or pinch required with no button alternative.

Fix: Add single-pointer alternatives (buttons) for swipe, pinch, and drag gestures (WCAG 2.5.1).

5. Orientation Lock

Issue: App only works in portrait or only in landscape.

Fix: Support both orientations unless essential (e.g., games). Users with mobility devices may have devices mounted in a specific orientation.

How Our Mobile Accessibility Scanner Works

Our free mobile accessibility checker analyzes your mobile website or app for common accessibility issues:

• ✅ Touch Target Size Validation: WCAG 2.5.5 requires touch targets to be at least 44x44 CSS pixels. Our scanner detects buttons, links, and form fields that fall below this threshold.
• ✅ Screen Reader Support: iOS VoiceOver and Android TalkBack rely on accessible names. Our tool checks that interactive elements have descriptive labels.
• ✅ Viewport and Zoom Configuration: The meta viewport tag must not disable zoom. Our scanner validates that users can pinch-to-zoom up to 200%.
• ✅ Gesture Alternatives: Complex gestures (swipe, pinch, drag) must have single-pointer alternatives. Our scanner checks for these.
• ✅ Color Contrast: Text and UI components must meet 4.5:1 (text) and 3:1 (UI) contrast ratios.
