GPS apps guess.
VlastLap measures.
Pro 100 Hz sensor-fusion telemetry from the phone in your pocket — speed, G-force, lean angle and lap times, measured 100 times a second, not estimated from GPS. No extra hardware.
iOS 15+ · Android 10+ · 4 languages
Right now, you're riding blind.
You brake where it feels right. The data says you lifted 30 metres early.
“I'm faster through there.” Now you can actually prove it. Or eat your words.
The best lap of your life — and no clue what made it good. Until now.
Numbers you can trust, a hundred times a second.
VlastLap fuses your phone's accelerometer, gyroscope and GPS into one fast, steady signal at 100 Hz. It reacts the instant you brake or accelerate — no GPS lag, no jumps — and tracks GPS truth to within about 3–4 km/h on real bike, car and kart sessions.
- → Mount it any way. Vertical or flat on the dash — the app works out the orientation itself in ~30 seconds.
- → Honest when it counts. Stuck at a light or in a tunnel with no GPS? The speedo stays at 0 instead of drifting.
- → Proven on real rides. Every release runs a regression suite against real recorded sessions — bike, car and kart — before it ships.
The data pros rely on — without the pro setup.

From the first corner to the bragging rights.
An instrument cluster that updates 100 times a second.
Analogue speedo with a ghost needle, a polar G-force meter, rotating compass and a tilting 3D map with your live position. Signal-quality indicator and custom alerts for traction, braking and lateral G.
Build your circuit on the map. See exactly where you're quick.
Drop draggable waypoints and the app builds the finish line for you. Crossing detection with no beacons, custom sectors, and a speed heatmap over your line — green slow, red fast.
Real-time delta against your best lap.
Every track day filed into sessions, stints and laps. See whether you're up or down, corner by corner, with a predicted lap time. At the end: best lap, top speed, max G and a consistency score.
Vehicle dynamics
Catches understeer and oversteer in real time. G-G diagram, braking and corner analysis, grip usage.
Rally co-driver
Pace notes on screen with direction, severity and distance. Works on roads you've never driven, offline with OpenStreetMap.
Engine data
Pair a Bluetooth adapter and log RPM, temperature, throttle and engine load alongside the telemetry.
Pro export
Take your sessions into Circuit Tools, MoTeC i2 or Google Earth — the same standard the pros use.
Remote coaching
Stream to the desktop app over WiFi or to the cloud: a coach watches your speed, Gs and position live from anywhere.
Synced charts
Speed, elevation, heading and Gs on one timeline. Tap a point on the chart and it marks the map. Line smoothed offline.
Bike, car or kart. The app adapts to you.
Pick your vehicle type and VlastLap tunes thresholds and calibration. Set make, model and power, choose your mount, pick km/h or mph, and choose from 7 theme colours and 4 languages.

- → Glanceable delta. Up or down vs your best lap, big and clear, right on the watch face.
The app today. The ecosystem tomorrow.
VlastLap starts as the pro telemetry in your pocket — and grows into hardware and integrations that scale with you. Here is what is on the way.
VlastLap Anchor
A module that lives in your car: a steadier, sharper signal, always on, with a direct line to your ECU over OBD.
VlastLap Halo
A dedicated estimator running at 1000 Hz — the resolution the pros chase, inside the VlastLap ecosystem.
CarPlay & Android Auto
Your live telemetry on the car's built-in screen — speed, G-force and lap delta, right where your eyes already are.
