Life360 follows the phone in your pocket. Trail-Safe runs on the watch on your wrist — Wear OS 4 and later — so your family still sees you when the phone stays at home.
Phones get left behind: in a school bag, a locker, on the kitchen table before a run. A watch stays on. With Trail-Safe the watch finds its own position by GPS and sends it over Wi‑Fi or LTE, so it does not need a phone nearby to share where you are.
What the watch does on its own
Live location
Your position on the family map, updated as you move.
SOS
One press alerts your family with your position — on every plan, the free one included.
Push-to-talk
Talk to your family walkie-talkie style, straight from the wrist (Family plans).
Recording and routes
Record a walk, or follow a route you drew or imported (paid plans).
Which watches work
Wear OS
Wear OS 4 and later: Pixel Watch, Galaxy Watch 4 and later, TicWatch, OnePlus Watch and more. Install from Google Play.
Garmin
The Connect IQ app is rolling out.
No watch?
Family members without a watch use the phone app, on the same family map.
LTE or Wi‑Fi?
A watch with LTE shares from anywhere with mobile coverage. A Wi‑Fi watch shares whenever it is on a network it knows: at home, at school, at the office. For hiking, running or children on their way somewhere, LTE is the one to pick.
Smartwatch questions
Does the watch need a phone nearby?
No. GPS, the connection over Wi‑Fi or LTE and SOS all run on the watch. You need a phone once, to set up the watch itself; after that it can stay at home.
Which smartwatch is best for family location?
One with LTE, so it can share away from Wi‑Fi. Trail-Safe works on Wear OS 4 and later.
Can family members without a watch join?
Yes. They install the phone app and share their location from there, on the same family map as the watches.
What does it cost?
The free plan covers your own watches and phone, with SOS. Sharing one map with up to 4 people is the Family plan, €8.99 a month.
