Scan any website for accessibility issues in seconds — and check color contrast anywhere, even live through your camera.
Accessibility Checker runs the industry-standard axe-core engine against any URL, explains issues in plain language, and turns your audit into an automated WCAG report plus a publishable accessibility statement — with an honest breakdown of what automated testing covers and what still needs human review.
Preparing for the European Accessibility Act (EAA)? Automated checks give you a fast baseline for EAA readiness. Full conformance always requires manual testing, and the app tells you exactly which WCAG criteria it can and cannot check automatically.
Everything runs privately on your device: the sites, images and colors you check never leave your phone.
THREE TOOLS IN ONE
1. Audit — run an automated accessibility test (axe-core) against any website and get a prioritized, plain-language list of issues with severity, affected elements and guidance for fixing each one. Export results as a text summary, CSV or an automated report PDF.
2. Focus Order — visualize the keyboard focus (tab) order of any web page, so you can see the sequence keyboard and screen-reader users follow, spot illogical jumps (WCAG 2.4.3), and export the full-page map as an image or PDF.
3. Color Contrast — measure the contrast between any two colors on a web page, in a screenshot, or live through your camera, against the WCAG 2.2 thresholds. View suggested passing colors, copy colors as HTML Hex or UIColor, and share annotated results. An experimental APCA (WCAG 3.0 draft) mode can be enabled in Settings.
WCAG 2.2 CONTRAST THRESHOLDS
For normal text, AA requires a contrast ratio of at least 4.5:1 (AAA: 7:1). For large text, AA requires 3:1 (AAA: 4.5:1). The app measures these for you and explains each result. Learn more at https://www.w3.org/TR/WCAG22/

The details don’t appear to clearly explain there is a monthly $.99 fee to use the app. You are basically forced to a screen to sign up for 7-Day free trial. Fine if that is the model - but make it clear in the app details up front so users know that before downloading. Feels like a bait and switch operation otherwise.
Developer Response
Thank you for the feedback - the upgrade screen has now been redesigned to make this clearer.
Important details not well thought
tanrenzu
When I load an app screenshot, the lower portion of the screenshot is blocked by the app’s bottom toolbar. This blocks from measuring all my screenshot’s accessibility.Also, the feedback email is broken, which doesn’t reflect an app that’s being paid attention and curated enough to request monthly payments for what could be simply bought once.Pity because otherwise seems like a clever and simple app.
Developer Response
Thank you for your feedback, we will address this feedback in an upcoming update.
Tricked into buying as free
SP_Brooklyn
Was checking out the app... Doesn't seem native for iOS... Get to one feature there's mostly a blank screen with an X button that only leads to 'buy ad free' version. Hit my home button to get out of it, but it of course completed a purchase.
Scam you into paying monthly fee
A&EsMom
No idea I had to pay monthly and I’ve requested multiple times to cancel but nobody cancels or responds to my feedback.

Hello, subscriptions can be managed via Settings, Apple Account, Subscriptions.
Made for iPhone Duo.
• Closed, it’s the Accessibility Checker you know, with its controls down the side. Open, it works as on iPad: the page fills the screen, its results sit on a card, and choosing an issue highlights it in the page. Opening or closing keeps your page, audit and colors.
Also new, on iPhone and iPad:
• Projects keep a site’s pages, results, statuses and notes (one project is free). Issues over time shows the trend, Recent lists the last 100 pages you audited, and a deleted project can be restored from Recently Deleted for 30 days.
• Log Issue records what you find by hand: type or dictate, add a screenshot, and choose from suggested WCAG criteria. It works from Shortcuts too.
• Focus Order finds elements that can’t be reached with the Tab key. Its findings and your contrast tests can be kept with the page in its project.
• Re-audit All Pages checks a whole project and tells you when it’s done. Add Links on This Page puts the pages it links to in the project, ready to audit. Export a project’s issues as CSV.
• Optional iCloud keeps your projects on your other iPhones and iPads, and on your Mac with Accessibility Checker for Mac 9.3 or later. It stays off until you turn it on.
