A viral one-tap “check-in” app made the idea famous overseas. SafePulse does everything that app does — then adds the safety features, the location, and the privacy it leaves out.
See the side-by-sideThe concept is great: check in regularly, and if you stop, the people who love you get alerted. SafePulse keeps that simplicity — one tap to confirm you're okay — but builds a real personal-safety system around it, and runs it on infrastructure you can actually trust.

When a viral safety app is owned overseas, your name, your contacts, and your location are the price of admission. SafePulse's Google Play and Samsung builds send alerts directly from your phone — no server in the middle, nothing collected, nothing sold.
Built by an independent US developer, with a privacy policy you can actually read.
Everything the viral app inspired — plus the parts that actually keep you safe.
Every alert includes your name and a map link to your last known location — so help knows where to go.
Trigger an alert instantly, and sound a siren to draw the attention of anyone nearby.
SafePulse warns you first — vibrating and opening the app — before it ever contacts anyone.
Up to 10 trusted contacts, organized into groups, each confirmed before they're ever notified.
If your phone is about to die, your circle is told — so silence isn't mistaken for an emergency.
No foreign server, no data harvesting. On Play and Samsung, your information never leaves your phone.
Published as SafePulse on Google Play, and as PulseGuard on the Amazon Appstore. Coming soon to the Apple App Store.
