About this app

Your phone is the drag strip — and now the race track too.

Race Stats turns your phone into a GPS performance timer for cars and motorcycles. Time 0-100 km/h and quarter-mile runs, watch your lean angle live through every corner, and log lap times — no extra hardware needed.

🏍️ NEW FOR RIDERS
• Live lean angle for both sides, with a rider that leans with you
• Max left and max right lean tracked separately, every session
• Lap timer: set your start/finish line and ride — laps are timed automatically
• Spoken lap times and gap to your best, straight to your headset
• Lap map of your best lap, coloured by lean angle or speed
• Share a session slip with your best lap, map and max lean
• Best lap, last lap and the gap to your best
• A garage for cars and motorcycles, with lean records per bike

🏁 DRAG & ACCELERATION TIMING
• 0-100 km/h (0-60 mph), 0-160, 1/8 mile, ¼ mile, 1 mile
• Custom speed ranges and rolling starts, e.g. 60-100 km/h (Pro)
• Auto-arm when stopped, auto-start the moment you launch
• GPS fused with the accelerometer for precise launch and finish detection
• Weather-corrected results (density altitude), like a real drag strip
• Estimated wheel horsepower from your run
• Personal best alerts on every run

📈 HISTORY & SHARING
• Every run saved with its speed curve
• Personal bests flagged automatically
• Compare two runs side by side
• Share a branded timing slip with your crew
• Export full telemetry as CSV

⚙️ MORE

• Metric and imperial units
• Your runs and garage are stored on your device

FREE AND PRO
Timing your runs and the live lean angle gauge are free. Race Stats Pro unlocks the lap timer, saved track sessions with lap maps, the g-force meter, the full garage and run history, run comparison, CSV export and external GPS support.

Ratings and reviews

App is not very reliable. Never starts measuring when the vehicle starts moving, and overall tested runs vehicle has been going 40 miles an hour or more before the app registers any speed. Kind of Misses most of the zero to 60 registering unrealistically fast time (that are wrong) or takes a long time to catch up to you moving the speed you are moving and registers incredibly slow times (that are wrong)

I used to use this app all the time, it was awesome. now you can't open the settings without it crashing, and it starts you in kilometers per hour which is insane. Y'all literally have my location why default to kilometers per hour when you could set a default based on the location.

Simple, neat, but could use some more options. It would be good if there was an option to select your start and end speeds, to allow for a rolling start. For instance it could wait for me to reach a steady 20mph then start the timer when I accelerate, then stop the timer when I reach 60mph.
