Free Contrast Checker for Mobile Apps

Ensure your mobile app meets accessibility contrast standards. Test UI colors for iOS and Android apps. Free WCAG contrast checker.

Mobile apps are used in wildly varying conditions — bright sunlight, dim rooms, while moving. High contrast isn't just an accessibility requirement, it's essential for usability. Both Apple's HIG and Google's Material Design guidelines mandate sufficient color contrast.

Tips for Mobile Apps

1

Test your app colors in bright sunlight simulation — outdoor readability requires higher contrast than indoor

2

Check contrast for interactive elements like buttons, toggles, and form inputs against their backgrounds

3

Verify that status indicators (success green, error red, warning yellow) are distinguishable for colorblind users

4

Test both your light and dark themes independently — each needs to meet contrast standards

Try This Example

“Check if my app's button color #6200EE on white #FFFFFF background meets WCAG AA for mobile interfaces”
