Solver: SOS & Personal Safety

Solver is a personal safety app for the moments you are on your own: walking home at night, a late train, a first date. One tap, and the people you trust know where you are.

ONE-TAP SOS
When something is wrong, one press starts a countdown, then alerts your guardians with your live location, by notification and by emergency text message. Your location keeps updating so they can follow you in real time until you are safe.

WALK HOME WATCHED
Start a journey home. If you stop responding or never arrive, your guardians are told.

CHOOSE YOUR GUARDIANS
Invite the people you trust; they accept, and you decide what each of them can see, from your live location to nothing at all. Every permission is per guardian and can be revoked at any time.

FAKE CALL
Need a reason to leave? Solver rings your phone like a real incoming call from a guardian's name, and a voice answers when you pick up. Nobody is actually called.

TALK TO YOUR GUARDIANS
A push-to-talk voice channel connects you to your guardians instantly, like a walkie-talkie, even from the lock screen.

EVIDENCE WHEN YOU NEED IT
Record video or audio during an incident. It is saved to your library and shared only with the guardians you chose.

ALARM
Sound a loud alarm in one tap to draw attention.

MEET ROGER, YOUR SAFETY ASSISTANT
Ask Roger to set a check-in, call you in five minutes, tell a guardian where you are, or simply keep you company on the way home. Roger also keeps your notes, tasks and reminders.

PRIVACY BY DESIGN
Your location is shared only with the guardians you authorised. Whenever a guardian requests your location, you are notified and it is logged. No ads, no data brokers, no tracking. You can delete your account and your data at any time.

THE SOLVER BUTTON (COMING SOON)
Pair the physical Solver button and trigger an SOS with a single press, without unlocking your phone. The button is optional: everything above works with the app alone.

Solver is not a replacement for emergency services. In a life-threatening situation, call your local emergency number.
