The Kart Lap Timer App With Sectors, Consistency and No Beacons
VlastLap is a 100 Hz kart lap timer that needs no beacons. Get reliable lap times, sector splits, a 0–100 consistency score and a heatmap straight from your phone.
Reliable, Repeatable Lap Timing at 100 Hz
In karting, hundredths decide the session — so your timer has to be repeatable. VlastLap's 100 Hz sensor fusion delivers lap times you can trust lap after lap.
- Automatic finish-line detection — no beacons to carry, set up or forget.
- Repeatable timing: you compare yourself against yourself, so the delta is clean and consistent.
- ZUPT pins you to a true 0 when you stop in the pits — no drift on the clock.
The 100 Hz reactivity means every brake, every G and every crossing is caught the instant it happens.
Sectors and Live Delta
Find your time, don't guess at it. VlastLap breaks the lap into pieces so you know exactly where it's hiding.
- Up to 10 sectors with split times per lap.
- Live delta to your best, updating at 100 Hz around the whole circuit.
- Predictive lap time so you know mid-lap whether it's a banker.
From ~8,500 built-in circuits, finish line and sectors are detected automatically — clip in and drive.
Consistency Score 0–100 and Heatmap
Fast laps are nice; consistent fast laps win races. VlastLap quantifies how repeatable you are.
- Consistency score 0–100 across your stint, so you can chase repeatability directly.
- Track heatmap showing where you're losing or gaining around the circuit.
- Lateral and braking Gs at 100 Hz to see how hard you're really pushing each corner.
Auto-calibration takes about 30 seconds with free mounting — no rig, no fuss.
Export, Smartwatch and Multi-Vehicle
VlastLap fits the rest of your toolkit and your whole garage.
- Export to MoTeC i2, VBO (Circuit Tools), KML and GPX.
- Smartwatch (Apple Watch / Wear OS) for delta, heart rate and haptic cues.
- Multi-vehicle: the same app adapts to kart, car or moto.
Remote coaching over WiFi or cloud lets a coach watch your stint live.
