The Motorcycle Lean Angle App That Reads Every Degree at 100 Hz
VlastLap turns your phone into a full motorcycle telemetry rig. Sensor fusion at 100 Hz captures lean angle, lateral Gs and braking the instant they happen — no external box required.
Lean Angle and Tilt Horizon, Live at 100 Hz
Lean angle is the headline metric for any rider, and VlastLap makes it the star of the screen. Our 100 Hz sensor fusion (IMU at 100 Hz blended with GPS) gives you a live lean readout and a tilted-horizon display that mirrors exactly how the bike is leaning into and out of every corner.
- Live lean angle with a tilted-horizon HUD you can read at a glance.
- 100 Hz reactivity so the number moves the moment you tip in, not a half-second later.
- Per-corner review to see where you carry more angle and where you bottle out.
Because the data updates 100 times a second, what you feel in the seat and what you see on screen finally agree.
Lateral Gs, Braking and Acceleration You Can Trust
Lean angle tells half the story — load tells the rest. VlastLap streams lateral and longitudinal Gs at 100 Hz so you can see how hard you're really braking, driving and cornering.
- Lateral G traces to confirm you're loading the tyre, not just hanging off.
- Braking analysis that shows trail-braking depth and release points.
- ZUPT (zero-velocity update) pins your speed to a true 0 at the lights or in a tunnel — no phantom drift.
Auto-calibration takes about 30 seconds with free mounting: clip the phone anywhere, ride off, and VlastLap learns the orientation for you.
Routes, Track Days and Rally Co-Pilot
From a Sunday road blast to a full track day, VlastLap logs it all and plays it back where it matters.
- ~8,500 circuits built in, with automatic finish-line detection — no beacons to set up.
- Up to 10 sectors, a heatmap and lap-by-lap delta so you see exactly where time goes.
- Offline rally co-pilot for road and rally stages when there's no signal.
The accuracy that matters for improving is the repeatable delta — you compare yourself against yourself, so the comparison is rock solid — combined with 100 Hz reactivity on lean, Gs and braking.
Smartwatch, Multi-Vehicle and Coaching
VlastLap follows you onto your wrist and across your garage.
- Apple Watch and Wear OS: live delta, heart rate and haptic cues without looking down.
- Multi-vehicle profiles adapt the app to moto, car or kart — the moto profile foregrounds lean angle and the tilted horizon.
- Remote coaching over WiFi or cloud so a coach can watch your data live.
Export to MoTeC i2, VBO (Circuit Tools), KML and GPX when you want to dig deeper in pro tools.
Reserve Your Place Before Launch
VlastLap launches on 1 September 2026. Right now we're opening a waitlist with 250 places.
