Lapster Racing: GPS Lap Timer

Works with RaceBox Mini S, Micro and Pro. No RaceBox yet? Time your laps with your iPhone's GPS and see exactly where the seconds go.

Lapster turns your RaceBox into a complete lap timer and telemetry system. And if you don't own one yet, your iPhone can time your laps too.

RACEBOX — ALL THREE MODELS RaceBox Mini S, RaceBox Micro and RaceBox Pro. Connect over Bluetooth or Wi-Fi, pull the sessions stored on the device, and every lap is timed, mapped and saved automatically.

NO RACEBOX? USE YOUR PHONE Start a session with your iPhone's GPS and get real lap times on any circuit. Live map, predictive delta, lean angle, and a separate 0-100 acceleration mode with its own personal bests.

EVERY LAP, IN DETAIL • Replay any lap on the map at 1x, 3x or 5x • Speed, position and time for every corner • Put your lap next to a friend's and see where the time went • Sector splits, top speed, G-forces and lean angle

TRACKS Official circuits with verified records, plus tracks you build yourself — drop the start/finish line and sectors straight onto the map. Every track keeps a leaderboard of the riders on it.

TRACK DAYS Find track days, book your spot, and read reviews from riders who were actually there — with their photos and lap times attached.

SHARE IT Send a lap or a whole session with a link, post a story, or export a poster for Instagram. Your profile keeps every stat and badge you have earned.

MESSAGES Direct and group chats with other riders, including voice messages.

ALSO INSIDE • Import your existing rides from the RaceBox app (CSV) • Weather recorded automatically for every session • Your garage: cars and bikes, with photos • Available in 14 languages
