COMPAREPRO

Two laps, side by side, on the same scrubber.

Open any two laps — from one session or two different days — and watch them play in lockstep. The shared transport keeps both videos seek-synced, the delta pane shows where you're gaining and losing time, and the GPS track map draws both lines so you can see the lift exactly where it happens.

Apexcast COMPARE — Lap 3 vs Lap 4 at Ridge Motorsports Park, shared transport with stacked sparkline lanes and delta
