Read full descriptionHide full description
The karting lap timer for drivers, coaches and teams. Time every lap from trackside with a tap or the volume buttons, run two drivers at once and pull sessions off your MyChron over Wi-Fi. LAP TIMER • One tap to start, one tap per lap — or the volume buttons, so your eyes stay on the kart • Two drivers at once: volume up marks a lap for one, volume down for the other; the same pair again in one tap • Undo the last lap, drop an out-lap from the stats, add a note about the setup • Works offline at the track; the session syncs when you are back online MYCHRON IMPORT (free, no limits) • AiM MyChron 5, 5S and 6 over Wi-Fi, straight to your iPhone — no laptop, no cable • Every session of the day in one run: lap times, top speed and RPM • Out and in laps are left out automatically YOUR PROGRESS • A personal best on every track, marked the moment you beat it • Session breakdown: best, average, spread and top-3 average • Pick the track by name or let GPS find the nearest one; the weather is saved with every session • Time a rival as the second driver — they don't need the app — and see the gap • A D to A+ class among WinLap drivers on the same track and category, once enough of them have raced there • Share a session as an image or a link HISTORY • Free: your 15 most recent sessions on screen. Nothing is deleted — older sessions open with Pro WINLAP PRO • Your full history, every track and season • Personal-best timeline, consistency score and the trend against your last session • Gap Analysis to the track record and every leaderboard • Your rank among the rivals you have timed, and how the gap moves over the season • Monthly digest: sessions, laps, tracks, records Dark or light theme, 9 languages.
