Only for iPhone
Free · In‑App Purchases
iPhone
Forecasts your quarter-mile time mid-pass, times your laps with a live delta, and puts the numbers on your video from a phone, GoPro, DJI or Insta360.
RaceTymr is a drag timer and a lap timer in one app. Pair a supported GPS receiver and it times every pass and every lap, forecasts your time while you're still running, and puts your numbers on your video.
DRAG
• Every pass as a timeslip: 60 ft, 1/8 mile and 1/4 mile, with trap speed.
• Speed runs like 0-60 mph, 60-130 mph and 100-200 km/h.
• A live forecast of your time while you're still pulling (Pro).
• Density altitude and slope on every run.
• Leaderboards for strips and tracks. Runs with video are verified.
TRACK
• Live lap timing with a running delta, sectors and a predicted lap.
• Live coaching corner by corner, then an AI debrief after the session. Your first debrief is free.
• Compare laps and sessions (Pro).
VIDEO
• Record on your phone, or connect a GoPro or Insta360.
• Export the clip with your numbers burned in, ready to post. 1080p is free; 4K without the wordmark is Pro.
ENGINE DATA
• Connect an OBD-II adapter such as the OBDLink MX+, or bootmod3 and MHD on a BMW.
• See your engine live under every run with the engine layers (Pro).
GARAGE
• Your cars and mods, synced to your account, on your public profile.
WHAT YOU NEED
Timing comes from an external GPS receiver. RaceTymr works with RaceBox, Dragy and Dual XGPS receivers. Your phone's location finds the strip or track; it doesn't time the run. Demo mode lets you try drag and track timing without hardware.
Use RaceTymr only at drag strips, tracks and closed courses where it's legal, and follow the rules of the venue.
RACETYMR PRO
Timing, results, boards, video and backup are free. RaceTymr Pro adds the live forecast and PB chase, engine layers, run and session compare, the AI coach after your first debrief, board filters, 4K exports without the wordmark, air history and home-screen widgets.
Pro is an auto-renewing subscription, billed monthly or yearly. Both plans start with a 7-day free trial for new subscribers. Payment is charged to your Apple Account when you confirm the purchase. The subscription renews automatically unless you turn it off at least 24 hours before the end of the current period. Manage or cancel it any time in your Apple Account settings.
