Someone knows when you should be back.

Leave a trip plan before you go. If you don’t check in, Traverse raises the alarm step by step, and tells you exactly what it did. Free.

/ Before you go

A trip plan takes a minute.

Four things, set once, and you can extend the plan from the trail.

Your route

Draw it or pick a saved one. Traverse shows distance, ascent and an estimated time.

When you will be back

The check-in time is what everything else hangs on. Add a margin.

Who to tell

An emergency contact with a phone number. They get an SMS only if you are overdue.

Optional: a rescue team

Share the plan with a verified rescue organization, and its staff can see it if it escalates.

/ If you don’t check in

The alarm goes up one step at a time.

Nobody is alerted while you are on time. Late by mistake? Check in, and the people who were told hear that you are back.

  1. 01 — 04Not back?

    The app asks you to check in or extend the plan.

  2. 02 — 04Your emergency contact

    Gets an SMS with the plan and your last known position.

  3. 03 — 04Rescue organization

    If you shared the plan with a verified rescue organization, its staff see it, with the full history.

  4. 04 — 04All clear

    Check in, and everyone who was alerted gets a message that you are back.

A partnership with mountain rescue is in progress. Until then, trip plans and SOS alert your emergency contact.

/ SOS

An SOS that never says more than it knows.

Hold for 3 seconds. The screen shows one of three states, and it only moves on when the next one is true.

SOS

Each status says only what we know.

  1. Prepared

    No data connection: an SMS to 112 and your contact opens on your phone with your coordinates. You press send.

  2. Sent

    It reached our server, and responders and your contact were notified. Nobody has confirmed it yet.

  3. Acknowledged

    A responder confirmed they have it. Only then does the app say so.

Traverse does not replace 112.
If you can call, call 112. Traverse depends on mobile signal, SMS delivery and our servers; it cannot guarantee a response or an arrival time.
/ How it holds up

Made for the places where phones give up.

Runs on our servers, not your phone

Plans are checked every minute on our side, so the alarm still goes off if your phone is dead or out of signal.

Last known position

While a plan is open, your phone sends its position whenever it has signal. That is what your contact and rescuers see.

Every step on record

Each alert, extension and check-in is logged, so you and responders can see exactly what was sent and when.

Maps that work offline

Save your route and the terrain before you lose signal, with the slope layer for avalanche terrain.

Free for good

Trip plans, SOS and live position will never be part of a paid plan.

A console for rescue teams

Verified rescue organizations see escalated plans and SOS calls with the route, last position and full history.

/ Questions
What is a trip plan?
Your route, when you expect to be back, and who to tell. If you do not check in by that time, Traverse reminds you, then texts your emergency contact 30 minutes later, then alerts a verified rescue organization at 90 minutes if you shared the plan with one.
Does it work without signal?
The alerts are sent from our servers, so they go out even if your phone has no signal or battery. Your position is only as recent as the last time your phone had signal. SOS without a data connection opens an SMS you send yourself, which needs at least mobile network coverage.
Is it a replacement for a satellite messenger?
No. Traverse uses mobile data and SMS. Where there is no mobile coverage at all, a satellite messenger or a phone with satellite SOS is the tool that can still reach someone.
Who sees my plan?
You, and only if the plan becomes overdue: your emergency contact by SMS, and staff of the verified rescue organization you chose to share it with. Nobody else.
Does the app call 112 for me?
No. If you can call, call 112. SOS without data prepares an SMS to 112 and your contact that you send yourself; with data it reaches our server and notifies responders and your contact.
Is it free?
Yes. Trip plans, SOS and live position are free and will stay free.
