// ABOUT
Letterproof grades the type around you. Point the camera at a menu, sign, slide deck, print proof, worksheet, UI mockup, or screen. Letterproof finds each visible line of text and rates it against WCAG 2.2 accessibility contrast thresholds. Each reading shows: - AAA, AA, or FAIL verdict - Exact contrast ratio, such as 4.51:1 - Sampled text and background colors - Estimated text size - A color-coded overlay on the source image - A practical contrast fix when a region falls below AA Letterproof is useful for designers checking a proof, teachers or parents reviewing low-vision readability, content teams reviewing signage or brochures, and anyone curious whether text in the real world is actually readable. Built privacy-first: - Vision text recognition runs on your iPhone or iPad - WCAG math runs on your iPhone or iPad - Photos and camera frames are not uploaded by the app - No account, sign-in, ads, tracking, analytics, or subscription - Audit history is saved locally on your device WCAG thresholds checked: - AA: 4.5:1 for normal text, 3:1 for large text - AAA: 7:1 for normal text, 4.5:1 for large text - Large text is treated as approximately 18 pt or larger Settings let you review results against an AA or AAA target. One-time purchase, no subscription.
