Laptime - Track Your Lap

Laptime turns your iPhone into a GPS lap timer for track days and closed circuits. Build a track, arm a session and drive. Every lap is timed, analysed and saved on your phone.

LIVE TIMING • Laps start and stop on their own each time you cross the start / finish line • Live delta to your best lap, so you know whether you're up or down • Sector splits as you cross each sector line • Full-screen Track Mode with speed and delta traces against your reference lap • CarPlay and Live Activities: lap time and delta on the car's screen, the Lock Screen and the Dynamic Island

EVERY LAP, ANALYSED • Lap time, top speed, average speed and peak G • Sector times for every lap • Speed, delta and G-force traces you can scrub through • A heat map of the lap on the map: see where you're fast and where you're slow • The weather when the lap was set: temperature, conditions and wind • Pick any lap as the reference to chase

YOUR TRACKS • Build any circuit or sprint in a minute: draw the route on the map, place the start / finish line and add sectors • Circuits loop and start the next lap automatically; sprints run once from start to finish • Tracks and laps are stored on your device. No account needed.

RACE YOUR FRIENDS • Share a track with a 6-letter code • Everyone's best laps on one leaderboard, with live delta against the fastest driver • Report or block anyone, and delete your account at any time

PRIVATE BY DESIGN Timing never needs an account, and your laps stay on your phone unless you share a track. No ads and no tracking.

DRIVE SAFELY Laptime is for track days and closed circuits only. Never use it to race on public roads, obey every speed limit, and set it up before you drive.
