Mobile Accessibility Checker

Mobile devices account for over 60% of global web traffic, and people with disabilities use smartphones as their primary internet access point at even higher rates. For many blind users, VoiceOver on iPhone is their only way to access the web. For users with motor disabilities, touch interfaces present unique challenges that desktop interfaces do not have.

WCAG 2.1 introduced several success criteria specifically targeting mobile accessibility:

• 1.3.4 Orientation — content must not be restricted to a single display orientation
• 2.5.1 Pointer Gestures — multi-point or path-based gestures must have single-pointer alternatives
• 2.5.5 Target Size — touch targets should be at least 44x44 CSS pixels
• 2.5.8 Target Size (Minimum) — WCAG 2.2 requires at least 24x24 CSS pixels

ADA lawsuits increasingly cite mobile accessibility failures. The April 24, 2026 ADA Title II deadline applies to mobile web experiences equally. A site that passes desktop accessibility testing may still fail on mobile.

CompliScan's scans detect many issues that disproportionately affect mobile users:

• Touch target size — links and buttons smaller than 44x44px are difficult or impossible for users with motor impairments to activate accurately
• Viewport zoom blocking — <meta name="viewport" content="maximum-scale=1"> prevents users with low vision from zooming in, a direct WCAG 1.4.4 violation
• Hamburger menu accessibility — mobile navigation menus that lack ARIA attributes, keyboard support, and focus trapping
• Horizontal scrolling — content that forces horizontal scrolling at 320px viewport width fails WCAG 1.4.10 Reflow
• Touch gesture dependencies — swipe, pinch, and multi-finger gestures without single-tap alternatives

Responsive design does not equal accessible design. A site that reflows correctly on mobile may still have tiny touch targets, blocked zoom, and inaccessible navigation.

CompliScan scans the rendered HTML of your website, detecting accessibility violations that affect both desktop and mobile experiences. Many mobile-specific issues are CSS and viewport-related and detectable in the rendered markup:

• Viewport meta restrictions — CompliScan flags maximum-scale, user-scalable=no, and other zoom-blocking viewport settings
• Form label associations — mobile forms with missing labels are especially problematic because VoiceOver and TalkBack rely heavily on programmatic label associations
• ARIA on mobile components — hamburger menus, bottom sheets, and mobile-specific UI patterns need proper ARIA roles and states
• Link and button accessibility — small touch targets and empty links are flagged with AI-generated fix suggestions

For comprehensive mobile testing, supplement CompliScan with manual VoiceOver testing on iOS and TalkBack testing on Android. Test your site's responsive breakpoints to ensure accessibility is maintained across all viewport sizes.

Use CompliScan as your automated baseline, then follow these mobile-specific best practices:

• Minimum touch targets of 44x44px — apply CSS min-width and min-height to all interactive elements; use padding to increase tap area without changing visual size
• Never block zoom — remove maximum-scale=1 and user-scalable=no from your viewport meta tag; WCAG requires users to be able to zoom to 200%
• Test at 320px width — all content must be available without horizontal scrolling at 320px viewport width (WCAG 1.4.10 Reflow)
• Provide single-tap alternatives — every swipe, pinch, or multi-finger gesture must have a single-tap or button-based alternative
• Test with real devices — mobile simulators miss touch-specific issues; test on actual iOS and Android devices with VoiceOver and TalkBack enabled

CompliScan's paid plans (from $49/month) monitor your site continuously, catching mobile accessibility regressions after responsive design changes and deployment updates.
