A GPS lap timer and lean-angle logger built for motorcycles. Record and analyze a whole track day with nothing but your iPhone. ◆ Made for bikes — lap times and lean angle Unlike a general-purpose lap timer, this app measures your bike's lean angle. Stand the bike upright before you set off and tap once — that is the whole setup. As soon as you start riding, the app learns which way the bike points from your GPS heading, so it records lean correctly no matter how your phone is mounted (portrait, landscape or angled). Right-hand lean is logged as R and left as L, and you keep the maximum lean angle for every corner. ◆ Build your own courses — local tracks welcome 28 preset circuits are included, covering every venue on the 2026 MotoGP calendar: Assen, Mugello, Silverstone, Circuit of The Americas, Jerez, Barcelona-Catalunya, Sepang, Phillip Island and more, plus Japanese circuits such as Suzuka, Motegi and SUGO. You can also draw your own. Place the control line, sectors and corners on the map and any local circuit or practice course becomes a timed course. Point-to-point layouts with a separate start and finish, such as hillclimbs, are supported alongside conventional lap circuits. ◆ Accurate lap timing Line crossings are interpolated from the GPS trace to give lap times accurate to 0.01 s relative within a session. Out-laps and any other laps you do not want are easy to exclude from the totals after you finish. ◆ Sector and corner analysis Every line you draw splits the lap into another sector, and each sector time is recorded and shown live while you ride. Entry speed and maximum lean angle are captured corner by corner, so the detail of your riding is there to see. ◆ Trend charts show your progress The more sessions you ride, the further your best lap, sector times, corner lean angles and corner speeds extend across the chart. Switch by course and by metric to see your improvement at a glance. ◆ Review it properly afterwards The session view puts the summary, laps, sectors, corners and a course preview on one screen. Open a lap for speed and lean-angle graphs, with each corner drawn on a motorcycle illustration tilted to the angle you actually reached. ----------------------------- Highlights - Everything runs on your iPhone. No account, no server, fully local - The screen stays awake while timing, so it stays readable on the move - Speed in km/h or mph, matched to your region or set by hand - Favorite courses for one-tap selection ----------------------------- For safe use - We recommend using this app in a safe, controlled environment such as a racing circuit. - When riding on public roads, always obey traffic laws and ride at a safe speed. - The app and its developer accept no liability whatsoever for any damages arising during use of this app. Here to support safe, enjoyable riding.
