SOS that says where you are
A deliberate three-second countdown, then an SMS with your coordinates, a siren, and a location log.
Each of these is in the shipping build today. Follow any of them for exactly what it does, which permissions it needs and whether it works without a connection.
Raise an alarm, tell people where you are, and confirm when you are safe.
A deliberate three-second countdown, then an SMS with your coordinates, a siren, and a location log.
Save up to five contacts from your address book. They receive your SOS alerts and your all-clear.
Light, direction, position and power — the four things you actually need.
Instant torch with an adjustable strobe, an automatic SOS Morse pattern and a red/blue screen flash.
A magnetic compass driven by your phone’s own sensors, with a calibration indicator so you know to trust it.
Coordinates in decimal, DMS or UTM, ready to copy, share or read aloud — plus a live speed readout.
Charge level, current draw, temperature, health and time-to-empty — because every other tool depends on it.
Reference material you want stored before you need it, not searched for afterwards.
Blood type, allergies, medications and conditions — stored on your device and attached to SOS alerts.
Cache an OpenStreetMap region while you have a connection, then browse it with your position on top when you do not.
Eight common emergency procedures, stored in the app and readable with no connection.
Emergency numbers for more than 130 countries, detected from your SIM and stored on the device.
Reach the tools without unlocking, hunting or scrolling.
Lock-screen SOS, a Quick Settings tile, a home-screen widget and launcher shortcuts.
Offline first
Dead zones, basements, foreign SIMs, flight mode, a network overloaded during a local incident. The core toolkit is built so none of those stop it working — and where something does need a connection, this is exactly which.

capabilities need no network at all
Flashlight, compass, first aid, emergency numbers, battery and your stored details all work in airplane mode.
GPS is not the internet
Your phone receives satellite signals to work out where it is. That needs no data plan, no Wi-Fi and no signal bars — which is why coordinates are available in places a map app is not.
SMS beats data under load
SOS alerts go out as text messages. They need cell signal — no app can send without it — but they often get through on a marginal or congested network when a call or a data connection will not.

Offline maps are the one feature with a genuine two-step story: you download an area while you have a connection, and from then on it works without one. Plan for that before a trip rather than during it.
Free on Google Play. No account, no subscription, and the core tools keep working when the signal does not.
