Only while the app is open and has signal
If you fully close the app, lose signal or run out of battery, your position stops updating. The web cannot track in the background when the app is fully closed.
Safety
Someone knows you're out there — and when you're due home.
Emergency-contact tracking is the heart of FERDEN. Share a secret link with someone you trust so they can follow along without downloading anything — and get alerted if something runs late. Free, always.
How it works
From plan to safe homecoming, step by step.
- 1
You plan the trip
Add your route and when you expect to be back. Everything set before you leave.
- 2
You share a secret link
FERDEN creates an unguessable link. Send it to your contact by text or chat — they need neither app nor account.
- 3
Your buddy sees the map
They open the link in a browser and see your planned route and last known position on a map.
- 4
Position updates as you go
As long as the app is open and you have signal, your last position updates along the way.
- 5
Run late, and they're alerted
If you pass your expected return without ending the trip, it's flagged as delayed — so your contact can react.
What your contact sees
- Your planned route
- Last known position
- Whether the trip is delayed
What they don't see
- Your profile or name in the app
- User ID or account
- Other trips or data
Honest about the limits
A tool — not a guarantee.
You send the text yourself
FERDEN opens a ready-made message in your own messaging app — we send no SMS on your behalf. You press send.
Not a replacement for emergency services
In an emergency, call your local emergency number. Always bring a map, compass and enough clothing — and consider a PLB in demanding terrain.
Always free
Safety is always free
Emergency-contact tracking and every safety feature are never behind a paywall — no matter what.
Share the safety on your next trip.
