Your Data
Everything you need after a track day
Speed, lean angle, lap comparison, corner coaching, and GoPro video overlay — processed automatically with plain-English insights that tell you exactly where to focus.
Speed Analysis
GPS-derived speed. Every metre of the lap.
The u-blox M9N GPS logs Doppler-shift velocity every 100ms — more accurate than position-derived speed. No phone GPS jitter, no dropped samples. See exactly where you gain and lose time against your best lap.
Braking zones are highlighted automatically. Spot late braking, early pick-up, and the exact moment you get back on the throttle compared to your reference lap.
- ✓10Hz GPS velocity — 10× more data points than phone apps
- ✓Doppler-shift measurement — no GPS drift error
- ✓Automatic braking zone detection on supported circuits
Lean Angle
±0.5° lean angle accuracy. Every corner.
The BNO085 IMU runs sensor fusion at 400Hz internally, outputting calibrated orientation quaternions. True lean angle is decomposed from yaw and pitch — compensating for acceleration forces that fool simpler implementations.
See your lean angle trace overlaid on your speed data. Identify corners where you're not committing, or where you're running out of lean before the apex.
- ✓50Hz lean angle logging — smooth traces, no aliasing
- ✓Sensor fusion compensates for cornering G-forces
- ✓Left and right lean tracked independently per corner
Lap Analysis
Compare any two laps. Find the seconds.
Overlay any two laps and see exactly where time is gained or lost. Sector-by-sector delta bars make it obvious which corners are costing you — no spreadsheets required.
Use your best lap as the reference and work backwards. Found 0.5s in Sector 3? Now drill into that corner with the coaching view.
- ✓Overlay any two laps from any session
- ✓Sector-by-sector time delta breakdown
- ✓Speed, lean angle, and throttle on the same chart
Corner Coaching
Plain-English coaching. No data science degree required.
The analysis engine compares your corner entry, apex, and exit against your own best lap — not some idealised reference. It finds patterns you’d miss in raw data and explains them in plain English.
Start with the corners costing you the most time. Fix one thing per session. Watch the delta improve.
- ✓Compares every corner against your own best lap
- ✓Entry speed, lean, throttle, and braking point analysis
- ✓Actionable suggestions, not just raw numbers
Issue Detected
Late braking at Druids
You braked 12m later than your best lap. Entry speed was 8mph higher, causing a wide line through the apex and costing 0.3s on exit.
Suggestion
Try braking 1 marker earlier
Reducing entry speed by ~6mph will allow a tighter line and earlier throttle application. This is where your best lap found 0.3s in Sector 2.
