Race Stats: Speedo and G Force

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.

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.
