Report a problem
Tell us your Android version, device model, app version, what you did, what happened and what you expected. Remove personal information from attachments. Never post a tester email list or private feedback in a public repository.
Install or update the test APK
Requires Android 8.0 or later. Download an APK from the app page and open it with Android's installer. Allow installation from your chosen browser only if you trust this development build. Install over a compatible development-signed version to preserve settings and patterns. Export your custom patterns before any uninstall. Camera permission is used only for the LED, not photography. Version 1.0.1 uses version code 2. Languages are available in Settings.
Download the Google variant for a Google-services phone or the Huawei variant for HMS testing. Both variants share one application ID and replace each other, rather than installing side by side. Commercial purchase restoration is store-specific. If Android reports a signing conflict, contact support before uninstalling: uninstalling removes private app data. The later production certificate may require a fresh installation. Do not disable Play Protect or other security protections.
Testing checklist
- Test camera and notification permission acceptance and refusal.
- Test LED, screen, timer and background behavior; check hardware-dependent intensity.
- Test patterns, JSON import/export, widgets and Quick Settings.
- Check Settings banners online/offline with lighting on/off and advertising refusal. Real commercial store/HMS validation remains pending.
Data removal
Settings, patterns and cached signed purchase records remain in private app storage until removed, app storage is cleared or the app is uninstalled. Android automatic backup is disabled. JSON imports and exports use the Android file picker and the destination you select; your selected storage provider may synchronize exported files under its own terms. Exported files remain after uninstalling and must be deleted separately. Removing app data does not refund purchases or erase records retained by stores or advertising providers.
Joining a test
Testing invitations and opt-in links will be supplied once a Google Play testing track is available. This page does not enroll you in a test. Report your experience honestly; no positive review is required.
