Everything is on the wrist.No phone. No charger. Just go.

Trail-Safe is a watch-only GPS tracker — no phone needed, ever. It records every fix, streams your position over Wi‑Fi (or LTE if your watch has it), and shares it with family — all from your wrist. An LTE watch isn’t required: any connected smartwatch works. Live now on Wear OS; Garmin is rolling out now — our Apple app ships under our consumer brand PaceGuard.

Wi‑Fi at the trailhead, hut, refuge or campsite is enough. The watch sends every fix itself — no phone relaying anything.

Illustration — Sam is an example wearer.

Any connected smartwatch.

No LTE plan, no companion phone. The app runs on the watch you wear, over the connection it already has.

Why Garmin differs: Garmin watches can’t receive push messages or stream audio. Instead the watch checks in with us — about every 5 minutes, and every few seconds while an SOS is open. Coming soon means we’re building it; this table changes as features ship.

Your family sees you.
Not your phone.

More than a dot on a map. Every fix carries speed, heading, elevation and GPS accuracy, plus the watch battery level and charging state, and the connection state at that moment — so a replayed track shows exactly where your signal dropped and came back.

The three questions everyone asks.

Do I need to bring my phone?
No. Trail-Safe is a watch-only app. GPS, network, SOS and recording all happen on your wrist. Your phone can stay in the car, at home, or nowhere at all.
Do I need a watch with LTE?
No, LTE is optional. Any connected smartwatch works. Wi‑Fi at the trailhead, hut, refuge or campsite is enough — the watch queues fixes when offline and syncs them the moment it reconnects.
What happens when I’m out of cell range?
The watch keeps recording locally and queues fixes on-device. When it reconnects to Wi‑Fi or LTE, the queue syncs to the dashboard automatically — nothing is lost as long as the watch survives the trip.
