Lapster vs Himawari CIRCUIT

GPS lap timer for cars, motorcycles and karts — on any circuit, with or without a RaceBox. 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 FOLLOW YOUR CREW Home is a feed of the latest rides of the riders you follow, with their personal bests, comments and reactions. One search field finds riders, tracks, sessions and teams. 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 drivers and riders on it. Records and leaderboards are kept separately for cars, motorcycles and karts. TRACK DAYS Find track days, book your spot, and read reviews from drivers and 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.

Himawari Circuit turns a day at the track into something you can look back on. It times your laps with GPS and records your driving line, speed and G-force together. After the session you can see, on the map, where you were quick and where you lost time. AUTOMATIC LAP TIMING Every time you cross the control line, a lap is recorded, along with sector times, top speed and average speed. Each lap time is announced out loud, so you never have to look at the screen while you drive. DRIVING LINES YOU CAN COMPARE Your line is drawn on the map, colored by speed or by G-force, so you can see where you are on the power and where you are not turning. Lay your own earlier runs over it, or line up runs from friends in the same group. In replay, up to four cars move at once, so you can watch the gap open up. SESSION VIDEO Record with your phone as you drive and play it back with your telemetry over it. Only your best lap is kept, and it never leaves your phone. YOUR SESSIONS ARE KEPT FOR YOU Sessions upload automatically when you finish. With no signal they stay on your phone and go up once you are back online. VEHICLES AND TIRES Record sessions per vehicle, with maintenance records and tire details, so you can trace how a setup changed your times. WITH YOUR FRIENDS Create a group to share sessions and leaderboards with its members. Live timing shows where your friends are on track, and their lap times, as they drive. EXTERNAL GPS RECEIVERS Works with RaceBox, DigSpice IV and the self-built Himawari GPS. A phone's built-in GPS updates about once per second; an external receiver updates far more often, which makes lines worth comparing. WHAT YOU CAN TIME Circuits and closed courses, and point-to-point runs such as hill climbs. -------------------------------- PLANS The free plan covers lap timing, session recording, the track list and leaderboards, and cloud sync of your sessions.
