FINDERR is the reference implementation of Finder-First Phone Recovery — a design paradigm for how lost phones actually come home.
✅ Emergency wallpaper + QR code — free on Google Play ✅ Web dashboard activation ✅ No credit card needed ✅ Android 9+ compatible
Your phone recovered in 4 steps — no unlock required on the finder's side
FINDERR turns your Android lockscreen into an emergency contact card with a QR code. The card is dormant by default — when you lose your phone, you log into the FINDERR dashboard from any other browser (a friend's phone, a laptop, a hotel kiosk) and remotely activate the emergency screen on your missing device. The lockscreen instantly displays your ICE contact information and a unique QR code, visible to anyone holding the phone without needing to unlock it. The finder reads your contact info or scans the QR — which opens a secure page at hub.untrapd.com/found — and calls you. FINDERR is free on Android. Premium adds remote emergency-contact updates (change the phone number a finder sees, without touching the lost phone) and, on the direct-download version, 13 SMS commands for remote phone control.
Install FINDERR. Add your emergency contact — name, phone, email. Takes 2 minutes. If you lose your phone, activate its emergency screen remotely from any browser.
