A paid audit service and free browser check for Flutter mobile apps, covering accessibility, App Store requirements, and Google Play readiness.

Landing page captured for the 2026-09-16 issue.

Field notes

The service separates what a platform can observe from what a developer must fix in source code. Its sample audit of Wonderous 2.2.7 covers eight iOS screens and reports 33 source locations, 161 occurrences, and 21 checks. A displayed example points to a specific Dart file and line where a 17×27 button falls below a 48×48 Android target-size minimum. The site also offers an in-browser check for .ipa, .apk, and .aab files without uploading them.
