Signal Flare
When a phone is about to die, it sends its last known location. This is where those flares land.
Create an account to see flares from your own devices and any that friends have shared with you — each one pinned on the map.

Signal Flare runs on your Android phone. When the battery drops to your chosen level — or you tap the big SEND FLARE NOW button — it sends your last known location here, and everyone linked to your account gets a map pin, a push notification, and an email.
- Install it. Download the app below and open the file. Android will ask you to allow installing from your browser — tap Allow / Install anyway.
- Log in. Open Signal Flare and sign in with the same email and password you use here — it connects to your account automatically (nothing to copy or paste).
- Choose who to alert. Pick a contact or type a phone number, and it's ready.
- That's it. Test it with the flare button, then turn on Alert automatically when the battery is low.
Android only. Requires Android 7 or newer.
