Himawari CIRCUIT
Read full descriptionHide full description
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. Times are interpolated between GPS fixes, so a lap is not lost when there is no fix at the moment you cross the line. 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. 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 and DigSpice IV. A phone's built-in GPS updates about once per second; an external receiver updates far more often, which makes lines worth comparing. If the connection drops, recording falls back to the built-in GPS, so nothing is lost. 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.
