Free macOS app
Accessibility checks, anywhere on your screen
A menu-bar toolkit for designers, developers and auditors: WCAG + APCA contrast picking, annotated issue captures, and live color-blindness simulation. 100% local — your screen never leaves your Mac.
Contrast picker
⌥⌘PFreeze the screen, pick text and background with a magnified pixel loupe, and get WCAG AA/AAA and APCA verdicts instantly. Drag across gradients to find the worst-case pixel, get one-click passing color fixes, and see how the pair holds up under four kinds of color-vision deficiency.
Capture & annotate
⌥⌘SGrab a region, drop numbered issue badges mapped to WCAG success criteria with severity levels, measure touch targets against the 24×24px minimum, redact anything sensitive, then export a GitHub- or Jira-ready issue list in one click.
Colorblind lens
⌥⌘LA floating lens that shows whatever is behind it through protanopia, deuteranopia, tritanopia or achromatopsia simulation — with a severity slider, low-vision blur and low-contrast filters, and a split before/after view for screenshots.

Questions
- Is it really free?
- Yes. The three tools are free with no account. A paid tier with full-page WCAG scans and PDF audit reports is planned.
- Why does it need Screen Recording permission?
- The color picker, captures and lens all read pixels from your screen. Everything is processed locally on your Mac — nothing is uploaded, ever.
- What does it run on?
- macOS 12 or later on Apple Silicon. A Windows version is on the roadmap.
