Turn data into speed

Where did your lap time go?

Drop in a session you already have and get a corner-by-corner breakdown: what each corner cost you against your own best lap, and how much of it was braking, minimum speed, apex, or the exit.

Tell us about the car optional · unlocks checks against your own numbers

Kept only for this analysis, like the file. Leave anything blank and that check is simply not made.

Reading the file

Alpha — a proof of concept. By uploading, you agree that what the engine measures from your session may be used to improve the analysis. Your file itself is analysed and deleted in the request. We keep what the analysis did — which checks passed, which measurements the engine could not make, how long it took — and we do not keep your file, your GPS trace, your filename, or anything naming you or your car. There is no account to make, and we do not ask who you are.
