A black drift car slides sideways around cones on a closed airfield at sunset, buried in tyre smoke

Lap timer app with drift score and lean angle Rubber belongs on the asphalt.

Lap times without pressing a button, a drift score with lateral G, lean angle in degrees. On the race track, the kart track, in motocross mud or on the airfield.

More smoke. Fewer excuses.

Track day, drag strip, airfield, gymkhana course: wherever timing is allowed, GhostShift gets everything out of your car or bike. On public roads the app only records, and you drive by the rules.

Kart track, pocket-bike course, motocross track or track day: fix your iPhone to whatever you ride and GhostShift finds the start/finish line by itself. Every lap timed, the fastest one marked, gaps and top speed on the map. If it has an engine and sky above, it counts.

Outdoors only: GPS needs open sky. In an indoor kart hall the clock stays at zero.

Quick answers.

Does it work in a kart, on a pocket bike or for motocross?

Yes, with anything that takes a solid mount: kart, pocket bike, motocross, supermoto, quad or buggy. Two-wheelers get bike mode with lean angle. The one condition is open sky: GPS has no reception in indoor kart halls.
