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.

NaviLens is a high-density artificial markers system for long distance reading. The tags generated by this system are designed in order to be read from a long distance, without the need of focussing and even in motion. This makes them useful for blind and partly sighted people. All you need to do is to point the camera of the device to a tag in order to quickly read its contents. The application has a new sound system with which a blind person can locate the label in the space with precision, without the need for headphones. Notice: While we are installing this signage system in different locations, you can download sample labels in the same application. We have spent 5 years to create this new technology. We will be happy to receive your impressions and comments about the system. For more information please read at the quick help, included in the application. The NaviLens team
