Analysis · 5 tabs

Five ways
to see your lap.

After a session LapVision opens analysis with five tabs. Switch between sectors map, speed graph, G-G diagram, 3D replay and lap table — one tap.

Map with sectors and deltas

Map with sectors and deltas

Satellite map with the lap trace, S1-S5 sector markers and deltas to best. Tap a point on the track — see speed at that meter.

  • Google Satellite / Streets / Esri tile layers
  • Best sectors auto-highlighted
  • Theoretical best lap from your best sectors
3D Replay with speed-coloured trail

3D Replay with speed-coloured trail

The killer feature. Replay the lap in first, second or third person. Trail colour changes with speed. Cameras: chase / drone / top-down. Playback speed 0.25× — 4×.

  • Satellite track texture — real top-down view
  • Driver car with user photo and avatar
  • Cross-session lap comparison mode
G-G acceleration diagram

G-G acceleration diagram

See where you braked without enough cornering load, and where you left boundary on the table. Each point is a moment, colour is speed.

  • Lat × Long acceleration at real scale
  • Visual hint where you can push further
  • Two-lap overlay
Two-lap compare

Two-lap compare
