The safety app that
shares nothing — until you need it to.
SOS is a check-in app for hikes, dates, and trips. Nobody tracks you in the background. You choose what to share, with who, and when — and if you don't check in, the right people find out fast.
Simple enough to use in seconds
Real screens from the SOS app on Google Play.
Not another tracking app
Life360 and its lookalikes watch you constantly. SOS only pays attention when you tell it to.
Location-tracking apps

SOS
- Location shared only during a check-in
- You pick exactly who's notified
- Real alerts — SMS + email — if you miss check-in
- Feels like having backup
Four steps, every time
Start a check-in
Hike, date, or anything else — add the details that matter, all optional.
Pick who's notified
Choose one trusted contact or several. Nobody else ever sees a thing.
Set a deadline
Check in by a set time, or extend it right from the app if plans change.
Miss it, and they're alerted
An SMS and email go out automatically with your details and last known location.
Everything's optional. That's the point.
Every field, every permission — off by default. Turn on only what a specific check-in needs.
Hike & trip check-ins
Trailhead, route, vehicle, who's with you — share as much or as little as you want.
Date check-ins
Who you're meeting, where, how you met, even their social handle — for your one trusted contact only.
Location, on your terms
Off, one-time, snapshot every 30 minutes, or live — you choose the level for every single check-in.
Photos & a current selfie
A real-time camera photo of what you're wearing, for the one scenario nobody wants to think about.
Trusted contacts
Save the people who should hear from SOS — nobody else ever gets pinged.
Real alerts, not notifications
Missed check-ins trigger actual SMS and email, sent automatically — even if your phone's off.

Good questions
Is this a replacement for calling 911?
No. SOS is a personal safety tool for trusted contacts — it doesn't dispatch emergency services and makes no guarantees about response times.
Who can see my location?
Only the specific contacts you pick for a specific check-in, and only if you turn location sharing on for it. Nobody else — not even SOS.
What happens if I check in on time?
Nothing. No alert goes out, and your trusted contacts never hear a thing — that's the whole idea.
Can I try it without an account?
Yes — the web version runs right in your browser. Accounts are only needed for SMS alerts and paid features.
