About

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 Free to use. Optional donations if you want to support development. Lapster is not affiliated with RaceBox. RaceBox is a trademark of its respective owner.
