What the app does.

The app does what only a phone can; the website shows the same tracker on any screen.

Pair and configure

Pair the tracker over Bluetooth and give it your SIM's network settings.

Arm and disarm nearby

Arm it when you park and disarm it when you're back, right next to the bike.

Alerts that reach you

Movement and geofence alerts arrive even when the app is closed.

Ride dashboard

Live speed, distance and G-force from the tracker while you ride.

What it needs

  • Android 7.0 or newer. Older phones can't install the build.
  • Bluetooth, to pair the tracker and to arm or disarm it when you're next to the bike.
  • Location permission on Android 11 and older, which the system requires for Bluetooth scanning. Newer versions use the Bluetooth permissions instead.
  • Notifications, so alerts can reach you when the app is closed.
  • A TechnikBrain account — the same one you use on this website.
