Test your mobile app or responsive website for accessibility compliance on iOS and Android.
Mobile accessibility ensures that websites and apps are usable by people with disabilities on smartphones and tablets. This includes touch targets, screen reader support (VoiceOver/TalkBack), zoom functionality, and gesture alternatives. WCAG 2.1 includes mobile-specific success criteria, and both ADA Title III and EAA explicitly cover mobile apps and responsive websites.
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.
Our free mobile accessibility checker analyzes your mobile website for touch target sizes, viewport settings, ARIA labels, and gesture alternatives.
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.
iOS VoiceOver and Android TalkBack rely on accessible names. Our tool checks that interactive elements have descriptive labels.
The meta viewport tag must not disable zoom. Our scanner validates that users can pinch-to-zoom up to 200%.

Now that you understand how our mobile accessibility scanner works, let's dive deeper into mobile accessibility requirements — including touch targets, screen reader support, viewport settings, gesture alternatives, and mobile-specific WCAG success criteria.
Mobile accessibility ensures that mobile websites and apps are usable by people with disabilities on smartphones and tablets. This includes users who are blind (rely on VoiceOver or TalkBack), have low vision (need zoom, high contrast), have mobility impairments (need touch target adjustments), or have cognitive disabilities (need simple, predictable design).
Mobile web accessibility and mobile app accessibility are both covered under WCAG 2.1, ADA Title III, Section 508, and EAA. Over 60% of web traffic now comes from mobile devices — making mobile accessibility more important than ever.
Mobile accessibility guidelines are defined by WCAG 2.1, which introduced mobile-specific success criteria. WCAG for mobile apps and WCAG for mobile websites share the same standards.
Accessibility standards for mobile apps under WCAG 2.1 Level AA include:
All functionality that uses multipoint or path-based gestures (swipe, pinch, drag) must also have a single-pointer alternative (tap, click). For example, a photo gallery that allows pinch-to-zoom must also have a + and - button for zooming.
For single-pointer activation, the down-event should not trigger the action. Users must be able to cancel by moving the pointer away before releasing. This prevents accidental activations.
For user interface components with visible text labels, the accessible name must include the visible text. This ensures screen readers announce the correct label for VoiceOver and TalkBack.
Functionality triggered by device motion (shaking, tilting) must also have a UI control alternative, and users must be able to disable motion actuation. This helps users with mobility impairments.
Touch targets (buttons, links, form fields) must be at least 44x44 CSS pixels. This is one of the most commonly cited mobile accessibility violations in ADA lawsuits. Exceptions include inline links in text and targets in a sentence.
Users must be able to switch between input methods (touch, keyboard, mouse, voice) without losing data or functionality.
Text must be resizable up to 200% without loss of content or functionality. For mobile, this means zoom functionality must not be disabled.
Content must reflow to a single column when zoomed to 400% on desktop or when viewport width is 320 CSS pixels on mobile. No horizontal scrolling required for reading.
Text must support line height, paragraph spacing, letter spacing, and word spacing overrides without loss of content.
Mobile screen readers are essential for blind and visually impaired users:
VoiceOver is Apple's built-in screen reader for iPhone and iPad. VoiceOver accessibility testing is essential for iOS app accessibility. Users navigate by swiping left/right and double-tapping to activate.
To test mobile accessibility with VoiceOver:
TalkBack is Google's built-in screen reader for Android devices. TalkBack accessibility testing is essential for Android app accessibility. Users explore by touching the screen or swiping with one finger.
To test Android accessibility with TalkBack:
Touch target size is one of the most important mobile accessibility guidelines. WCAG 2.5.5 requires touch targets to be at least 44x44 CSS pixels.
Why 44x44 pixels? Research shows that 44x44 pixels provides enough area for users with motor tremors, limited dexterity, or other mobility impairments to reliably activate a target without accidentally hitting adjacent targets.
Common touch target failures:
Touch target fix:
button, .button, a {
min-width: 44px;
min-height: 44px;
padding: 12px;
}iOS app accessibility requires following Apple's accessibility guidelines and WCAG 2.1 Level AA:
iOS accessibility label for VoiceOver is set using accessibilityLabel in UIKit or .accessibility(label:) in SwiftUI.
Native mobile app accessibility guidelines for iOS are available from Apple's Human Interface Guidelines.
Android app accessibility requires following Google's accessibility guidelines and WCAG 2.1 Level AA:
Android accessibility label for TalkBack is set using android:contentDescription in XML or setContentDescription() in code.
Native mobile app accessibility guidelines for Android are available from Android Accessibility Help.
Mobile web accessibility ensures responsive websites work on smartphones and tablets. Mobile accessibility best practices include:
The meta viewport tag must NOT disable zoom:
<meta name="viewport" content="width=device-width, initial-scale=1">❌ Don't use: user-scalable=no or maximum-scale=1.0 — these disable pinch-to-zoom for low-vision users.
Zoom functionality must allow users to zoom up to 200% without loss of content or functionality.
Content must reflow when zoomed to 400% on desktop or when viewport width is 320 CSS pixels on mobile (WCAG 1.4.10 Reflow).
Common responsive failures:
All interactive elements (buttons, links, form fields) must meet 44x44 pixel touch target requirement.
For complex gestures (swipe, pinch, drag), provide single-pointer alternatives (WCAG 2.5.1 Pointer Gestures). For example, a swipeable image carousel should also have Previous/Next buttons.
Mobile accessibility testing should include both automated and manual methods:
iOS manual testing with VoiceOver:
Android manual testing with TalkBack:
Mobile device testing checklist:
WCAG for mobile apps and WCAG for mobile websites share the same success criteria, but implementation differs:
| Aspect | Mobile Website | Mobile App | |--------|----------------|------------| | **Viewport** | Must set viewport meta tag | Not applicable | | **Zoom** | Must allow pinch-to-zoom | Use Dynamic Type or system font scaling | | **Touch targets** | 44x44 CSS pixels | iOS: 44x44 points, Android: 48x48 dp | | **Screen reader** | VoiceOver/TalkBack with HTML | VoiceOver/TalkBack with native accessibility APIs | | **Focus order** | Tab order from DOM | Accessibility focus order programmatically set | | **Orientation** | Responsive design | Support portrait and landscape | | **Motion actuation** | Deviceorientation events | Use Core Motion (iOS) or Sensor Manager (Android) |WCAG for apps requires understanding platform-specific accessibility APIs (iOS: UIKit accessibility, Android: Accessibility Framework).
WCAG 2.1 mobile standards apply equally to both web and native apps.
Accessibility in mobile design starts early. Accessibility guidelines for mobile apps during design phase:
Mobile accessibility laws require compliance for mobile apps and websites:
ADA applies to mobile apps as "places of public accommodation." Banking apps, e-commerce apps, restaurant ordering apps, and healthcare apps must be accessible. Lawsuits citing inaccessible mobile apps have surged in recent years.
Federal agency mobile apps must meet WCAG 2.1 Level AA. State and local government apps must also comply (under Title II of ADA).
EAA mobile app requirements apply to e-commerce, banking, transport, and telecom apps. Enforced from June 28, 2025. Non-compliance fines up to €100,000.
AODA requires accessible mobile apps for public and private sector organizations with 50+ employees.
Problem: Buttons or links under 44x44 pixels
Fix: Increase click/tap area with padding:
button, .button { min-width: 44px; min-height: 44px; padding: 10px; }Problem: user-scalable=no or maximum-scale=1.0 in viewport
Fix: Remove these from viewport meta tag:
<meta name="viewport" content="width=device-width, initial-scale=1">Problem: 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>
Problem: Swipe or pinch required with no button alternative
Fix: Add single-pointer alternatives (buttons) for swipe, pinch, and drag gestures
Problem: 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.
Problem: Text contrast below 4.5:1
Fix: Adjust colors to meet WCAG 2.1 AA (4.5:1 normal text, 3:1 large text)
Mobile accessibility ensures that mobile websites and apps are usable by people with disabilities, including those who use screen readers (VoiceOver, TalkBack), need zoom functionality, or have mobility impairments requiring larger touch targets.
WCAG for mobile includes success criteria: 2.5.1 Pointer Gestures, 2.5.2 Pointer Cancellation, 2.5.3 Label in Name, 2.5.4 Motion Actuation, 2.5.5 Target Size (44x44px), 1.4.4 Resize Text (zoom), and 1.4.10 Reflow.
Use VoiceOver (iOS) or TalkBack (Android) to test screen reader compatibility. Test touch targets manually. Use automated tools like AccessiTool's mobile accessibility scanner.
WCAG 2.5.5 requires 44x44 CSS pixels for touch targets. For iOS native apps, 44x44 points. For Android native apps, 48x48 dp.
Because developers use user-scalable=no or maximum-scale=1.0 in the viewport meta tag. This violates WCAG 1.4.4 and prevents low-vision users from reading content.
Yes. The European Accessibility Act (EAA) covers mobile apps for e-commerce, banking, transport, and telecom services. Enforced from June 28, 2025.
VoiceOver is Apple's built-in screen reader for iOS. It allows blind and visually impaired users to navigate iPhone apps using gestures and spoken feedback.
TalkBack is Google's built-in screen reader for Android. It provides spoken feedback and gesture-based navigation for blind and visually impaired users.
Native mobile app accessibility guidelines for iOS include VoiceOver support, Dynamic Type, minimum 44x44 touch targets, color contrast 4.5:1, and respect for Reduce Motion setting.
Add accessibility labels for screen readers, ensure touch targets are at least 44x44, support zoom functionality, provide gesture alternatives, test with VoiceOver/TalkBack, and follow mobile accessibility best practices.
