Your ride, replayed.
Turn your phone into a vehicle telemetry logger — record GPS + motion, then replay every run on a map with G-force, lean and harsh-event analysis.
App Store Google PlaySee it in action
Every session, at a glance
Sport runs, drives and journeys side by side — with times, duration and capture mode. No file names, no fuss.
Harsh-event markers
Hard braking 🛑, hard cornering ↪ and hard acceleration ⚡ plotted right on your track. Tap a marker to jump to that moment. Three sensitivities: Strict, Normal, Circuit.
Travel mode
A low-power journey logger for trips — walk, train, car. Playback shows an activity icon and trip odometer that follow your speed.
Tune it your way
Sensor rates for battery, travel presets with auto-stop, and analysis thresholds — from gentle-driving review to circuit-only forces.
What it does
Record
- GPS track + up to 100 Hz IMU (accelerometer + gyroscope) to a simple, open NDJSON file. Sensor rates are adjustable to save battery.
- Travel mode: a point every few metres — log a whole trip day, not just a session.
- Background recording (Pro): keep logging with the screen off or your navigation app on top — made for the bike, where the nav owns the screen.
Replay & analyze
- Your ride on an OpenStreetMap track, with a scrubbable timeline.
- G-G diagram (friction circle), switchable vehicle gauge — top-down (G + yaw), rear (lean), side (pitch) — or a journey gauge for travel logs.
- Harsh-event detection: braking / cornering / acceleration events as tappable map markers.
Own your data
- Open NDJSON format you can parse yourself — see the data-format reference.
- GPX / KML export (Pro): open your route in Google My Maps, Google Earth, Strava and more.
- No account, no cloud, no analytics, no tracking.
