About this app

Race Stats turns your phone into a GPS speedometer and performance meter for your car.

Whether you're chasing a faster 0–100, dialing in your launch, or just want an accurate readout of how fast you're really going, Race Stats measures it with GPS and your phone's motion sensors — no extra hardware required.

📟 GPS SPEEDOMETER
A smooth, accurate digital speedometer reads true GPS speed in km/h or mph. Kalman-filtered for a stable, responsive readout that's more honest than your dashboard — with a clean, high-contrast display made for the car.

⏱ ACCELERATION TESTS
Run true acceleration benchmarks with automatic timing. Just come to a stop — the app arms itself, detects when you launch, and stops the clock the moment you hit the target.
• 0–100 km/h (0–62 mph)
• ¼-mile elapsed time + trap speed
• Distance and altitude-change tracking for every run

🎯 G-FORCE METER
A real-time g-meter tracks acceleration, braking and cornering forces. Calibrate once, then capture your peak accel, brake, and left/right cornering G.

🏎 POWER ESTIMATE
Add your car's weight and Race Stats estimates peak wheel and crank horsepower from your acceleration curve.

🚗 MULTI-CAR GARAGE
Keep a profile for every car you drive. Each one tracks its own best 0–100, best ¼-mile, and top speed.

📊 RUN HISTORY & SHARING
Every run is saved with a speed graph. Compare runs side by side to see your progress, and share a clean result card with your friends.

⚙️ BUILT FOR ENTHUSIASTS
• Metric and imperial units
• Dark, high-contrast display made for the car
• Maintenance reminders

Race Stats is for off-street, track, and private-road use. Always drive responsibly and obey local laws.

Note: GPS-based measurements are estimates and depend on signal quality. Treat power figures as a ballpark, not a dyno reading.

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.

What’s new

Introducing Circuit — track mode for riders.

• LEAN ANGLE: Watch your lean angle live and track your deepest lean left and right. Calibrates to any phone mount.

• GPS LAP TIMING: Set your start/finish line once. Laps are detected and timed automatically, with your delta to best on every crossing.

• SESSION HISTORY: Every session saved per bike — laps, best lap, top speed, max lean and peak cornering G, with your best lap charted.

Circuit is part of Race Stats Pro.
