TripRank turns your phone’s motion sensors into a four-axis G-force radar: lateral load through corners, longitudinal load under braking and acceleration, and combined G when both happen at once — sampled at 50Hz, displayed live, and recorded into every trip.
-
Live G radar
See cornering, braking, and acceleration load as it happens, on phone or CarPlay.
-
Recorded per trip
Every event flagged and timestamped — peak G, where it happened, how it built.
-
Smoothness scored
Rate of change matters more than peaks. TripRank scores how progressively load builds and releases.
Reading the trace, not chasing the peak
A high peak G number is easy to produce by accident — a swerve spikes lateral G as fast as a committed corner does. The trace shape is the honest signal: a smooth corner draws a rounded arc, a ragged one draws a spike and a correction. The journal covers what the numbers actually mean.
From live readout to permanent record
The live radar is the show; the record is the value. Every braking event and committed corner is flagged with its peak load and timestamp, so after the drive you can scrub through the trip and see exactly where the car worked hardest. Over weeks, those events become a picture of how you actually drive — not how you remember driving.
Details that matter
- 50Hz sampling. Fast enough to catch how load builds, not just where it peaked.
- Four axes, including combined G. Braking while turning is where grip actually runs out; a single lateral number hides it.
- Mount your phone. A solid cradle keeps sensor noise out of the data — and keeps you legal. Loose-phone readings are noise, not measurement.
- Feeds the Smoothness Score. The same stream that draws the radar scores how progressive your inputs were.
