Pilots
METARs, TAFs, winds aloft, PIREPs. See the weather at altitude before you climb. The only personal tracker with aviation weather built in.

without the satellite tracker.
Breadcrumbs Mobile turns your iPhone — with T-Mobile T-Satellite — into a personal location tracker, weather station, and emergency communicator. No extra hardware. No learning curve.
Free · via Apple TestFlight.
Important - we only need testers having T-mobile satellite service enabled
Why your phone is the right device
- Two-way satellite messaging now ships in every modern iPhone — the original killer feature of $400 communicators is now built in.
- Your T-Mobile satellite subscription works for more than emergencies. Texting friends. Maps. Breadcrumbs. One subscription, many uses.
- One device — not a tracker plus a phone. Cheap satellite communicators still need your phone for full messaging. So you'd carry both anyway.
- Cheaper. Free to start. Pro for the price of a coffee per month. No $400 hardware up front.
The honest catch: your iPhone isn't a $400 IP68 brick. If you're rock-climbing or whitewater kayaking with a thin case, a dedicated tracker is more drop-and-dunk-proof — but you'd still carry your phone for everything else.
Who it's for
Off-roaders & overlanders
Auto-track your route through canyon country. Let your people know when you made it through Black Bear Pass — without stopping to check in.
Boaters
Jet boats on the Snake River. Sailboats out of cell range. Kayakers on the coast. Track your route, send status, see the weather offshore.
Field researchers
Configurable 1-minute intervals. GPX export to QGIS or Google Earth. Long-term storage of every track you've ever recorded. Your remote fieldwork, mapped.
