LapTwin compares what you are doing with what the reference driver did at exactly the same point on track — brake, throttle, speed, steering, and racing line.
LapTwin is free during Alpha. Every contribution helps move the project forward.
Every view is designed to be understood at a glance, placed where you want it, and hidden when it is not useful.
Compare YOU and TARGET traces at the same point on track. Enable only the channels you need: brake, throttle, speed, or steering.
This overlay combines TARGET / YOU pedals, distance to the next braking point, and speed delta in one compact view.
Compare your lateral position with the Garage61 GPS line at the same track position. An arrow shows which way to reposition the car when confidence is sufficient.
Position is acquired in meaningful corners. LapTwin shows LOCATING instead of inventing a measurement on an information-poor straight.
LapTwin turns differences into short, deterministic guidance without sending your telemetry to the cloud.
Get the three most useful observations after corner exit: braking point, minimum speed, throttle application, and a priority for the next lap.
The car progressively learns its own observed envelope, even without a reference. With a compatible reference, compare your usage with the target lap.
This is a learned performance estimate, not an absolute physical tyre measurement.
Use the three-tone countdown or a sound whose intensity follows the reference brake-pressure trace.
Available in DEV. Garage61 determines which laps your account can access. Manual CSV import remains available.
Change the whole experience instantly with eight free themes: the app and every active overlay adopt the selected palette together. No theme depends on levels or challenges.
The installer places LapTwin on your computer and creates shortcuts. You do not need Python or Codex to run it.
