Accessibility Checker
The complete WCAG compliance tool for iOS and macOS. Evaluate color contrast, run automated audits, and get smart fix suggestions — all without installing a single browser plugin.
Why Accessibility Checker?
Everything you need to ensure your designs are accessible to everyone.
WCAG 2.x Compliance
Test against WCAG 2.1 and 3.0 (APCA) contrast guidelines. Get instant pass/fail results for A, AA, and AAA conformance levels.
Smart Color Suggestions
Don't just find problems — fix them. Get intelligent color alternatives that maintain your design intent while meeting accessibility standards.
Automated Auditing
Run comprehensive accessibility audits powered by axe. Identify issues beyond color contrast — from missing labels to incorrect ARIA attributes.
Works at the OS Level
No need to install plugins for Figma, Sketch, Adobe XD, or every browser. Accessibility Checker works at the operating system level, so every app and website is automatically supported.
Simply pick any two colors on screen and instantly see the contrast ratio, WCAG compliance level, and suggested alternatives if needed.

WCAG Compliance Made Simple
WCAG 2.1 has three conformance levels. For normal text, AA requires a 4.5:1 contrast ratio and AAA requires 7:1. For large text (18pt+), AA requires 3:1 and AAA requires 4.5:1.
Accessibility Checker also supports the experimental APCA algorithm referenced in WCAG 3.0, giving you a head start on future standards.
