FINDERR is a professional Android phone recovery app that uses an emergency wallpaper system to help recover lost phones. It is the world's first app to modify the Android system lockscreen remotely — displaying your contact info and a QR code directly on the lockscreen when activated. Activation is triggered via the FINDERR web dashboard from any browser, anywhere. The emergency display appears instantly without requiring anyone to unlock the phone. FINDERR is available free on Google Play and runs on Android 8.0 and above.

How does FINDERR help recover lost phones?

FINDERR recovers lost phones by making the owner's contact information visible on the lockscreen, so any honest finder can return the device without needing to break in. When you lose your phone, activate emergency mode via the FINDERR web dashboard from any browser. FINDERR instantly changes the lockscreen wallpaper to display your recovery contact details — including phone number, email, and a QR code. The QR code links to a secure web page where finders can see your contact info and help return the phone.

Yes, FINDERR's core protection is free. The free tier includes the emergency wallpaper with your phone number, in-app contact editing, and basic web dashboard activation. Premium adds QR code and email on the wallpaper, full remote management, live contact editing from any browser, and cross-platform sync. Recovery rate goes from ~25% (phone only) to ~65% (multiple channels). Plans start at €8.99/month or €89.99/year.

How does the emergency wallpaper work?

The FINDERR emergency wallpaper works by replacing your phone's system lockscreen wallpaper with a custom image that prominently displays your emergency contact information. Activation is triggered remotely via the FINDERR web dashboard from any browser. Once triggered, the app modifies the Android system wallpaper API directly, bypassing overlay restrictions so the contact info appears on the true lockscreen. When you recover your phone, deactivate via the web dashboard to instantly restore your original wallpaper. SMS activation commands are available in the direct download version.

Is FINDERR available for iOS?

FINDERR is currently Android-only (Android 8.0 and above). Due to iOS restrictions on lockscreen and wallpaper modification, the core emergency wallpaper feature is not technically possible on iPhone. FINDERR focuses exclusively on Android to deliver the deepest possible system integration and the most reliable lockscreen recovery experience.
