LAP＆LEAN vs RaceLine

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.

RaceLine turns your iPhone into a precision motorcycle telemetry computer. Record every ride with GPS, lean angle, speed, and braking — then relive it through a customizable share card built for Instagram, Messages, and AirDrop. Built for street riders, track-day enthusiasts, and weekend canyon carvers who want the data without strapping a dashcam to their helmet. KEY FEATURES • Live ride recording — GPS route, real-time speed, distance, and duration • Lean angle telemetry — your iPhone's motion sensors track left and right lean to the degree • Street and Track modes — Track mode includes a closed-circuit safety acknowledgment • Garage — manage every bike you ride, with year/make/model pulled from the open NHTSA vehicle database • Maintenance log — record oil changes, chain service, and tire dates with mileage-based reminders • Custom share cards — generate a 1080×1920 ride card with your photo, your route, and your colors, ready for Instagram Stories • Cloud sync — sign in with Apple or Google; your rides follow you across devices • Account control — full account deletion is built into the app WHY RACELINE Most motorcycle apps either gate features behind a subscription or treat your iPhone like a passive recorder. RaceLine is built around what your phone is already great at — a high-resolution GPS chip, accurate motion sensors, and a bright display — surfaced through a dark, fast UI designed to be glanceable through a tinted visor. No subscription. No ads. No upsell. PRIVACY RaceLine never tracks you across apps, never shares data with advertisers, and only collects location and motion data while you are actively recording a ride. Your data syncs only to your account on RaceLine's encrypted backend, and you can wipe everything from Profile → Delete Account. IMPORTANT RaceLine is not a lap timer or official timing device. Use Track mode only on closed circuits, and always ride within your limits and the law.
