EARLY ACCESS: ApexLap is being tested on track right now, and it is free while we test.

Time your laps on a circuit, a kart track or a closed course with your Apple Watch or your iPhone. See every lap, your best sectors and where you gain or lose time, and get a coach that talks to you between corners.

• Lap and sector times from GPS, in both directions of a track • Your own tracks: record one, then move the start/finish line, sectors and corners • Personal bests per track, vehicle and direction • Live coaching from your own best lap, on your wrist or through your headphones • Your sessions, vehicles and tracks on all your devices with an account

Times are estimated from GPS and are not official timing. Braking zones, acceleration and the racing line are estimates. Use it only where driving fast is allowed, and never let the app take your eyes off the road.
