  1. Load a lap

    Drop a MoTeC .ld/.ldx or a SimHub/custom .csv — parsed in your browser, nothing uploaded.

  2. Pick two laps

    ApexTrace detects every lap. Choose a reference A and a comparison B.

  3. See where time goes

    Read the cumulative time-delta trace with synced speed, throttle, brake and steering — pinpointing every corner you gain and lose.

Drop telemetry to begin

Drag a MoTeC .ld or a .csv log here (drop a .ldx with its .ld for beacon laps)

Everything is parsed in your browser — your telemetry never leaves your machine. Mix sources freely: compare a .csv lap against a MoTeC .ld lap.
