BUILT FOR ANDROID™
BERT is a real Android home-screen widget—not a web shortcut. It uses native widget sizing, scheduled background refreshes and private on-device storage for your optional holdings amount.

THE WIDGET
Choose Compact 2×2 or Market 4×2 directly in Android’s widget picker. Market adds market metrics and the live USD value of holdings you enter locally. Tap either widget for the full market desk, refresh controls, source details and one-tap widget setup.

Illustrative market snapshot. The installed widget displays current validated data.
THREE STEPS. NO CEREMONY.
Use the button on this page. Android may show a warning because the app comes directly from Berthalla, not Google Play.
Allow your browser to install the APK. You can disable that browser permission immediately afterward.
Open BERT once, then long-press your home screen → Widgets → BERT. Choose Compact 2×2 or Market 4×2 and drag it into place.
TRUST, WITH RECEIPTS
The app has no sensitive or runtime permissions. Optional holdings are stored only in private app storage and never transmitted. Internet and network access retrieve market data; standard wake, boot and foreground-service permissions let Android schedule refreshes. There is no wallet code, account system, advertising SDK or analytics tracker.

The Android app, widget and quote service are publicly available for inspection. Review how market data is validated, confirm holdings stay on-device, audit every permission, or build the project yourself.
QUESTIONS, ANSWERED
The APK is distributed directly rather than through Google Play. Confirm the domain is berthalla.io and compare the SHA-256 above before installing.
No. There is no wallet connection, signing, trading or account flow. The widget displays informational market data only.
Only in the app’s private storage on your device. The amount is used locally to calculate the Market widget’s USD value and is never sent to Berthalla or a third party.
The app requests a background refresh every 15 minutes. Android ultimately controls scheduling and may delay work to preserve battery. The widget shows the quote age and marks delayed data.
Return to this page for new releases. Download the newer APK and install it over the existing app; your widget placement should remain intact.
Not yet. The current release is Android-only. An iPhone edition requires a separate native app and WidgetKit extension plus Apple signing and TestFlight or App Store distribution; that build has not started yet.
