Add your timing data

Whatever recorded it. We will time the laps with the same engine we use for everything else, tell you how good the measurement was, and check our lap count against your device’s.

Drop your lap logs here

SpeedAngle .sa, a DashWare or RaceChrono CSV, or any CSV at all — the only thing we actually need is a position and a timestamp on each row. Everything else just adds detail.

Drop a whole day at once if you like. We work out from the gaps which files are one outing that paused and which are separate outings.

Nothing is uploaded. Your file is read in this browser, and you decide afterwards whether to save it.
