0-60 Drag Race Timer: GPS

Turn your iPhone into a high-precision drag race timer. Measure 0-60 mph, 0-100 km/h, the 1/4 mile and more — GPS and accelerometer fused at 20 Hz, no $150 box required. Drag Race is built for one thing: nailing your acceleration times and helping you go faster. Every run is detected automatically — arm it, launch, and the timer does the rest hands-free. TIMES THAT MATTER • 0-30 and 0-60 mph, 0-50 and 0-100 km/h • 1/8 mile and 1/4 mile, both with trap speed • 60 ft time and automatic in-run splits • Reaction time and a launch quality score • Custom targets from 10 to 400 km/h — pick any speed you want GPS + ACCELEROMETER FUSION • Sensor fusion at 20 Hz — more precise than GPS-only apps • Launch detected by the accelerometer — the clock starts at the real launch, not when GPS catches up • Live GPS readiness tells you when it is safe to launch • Barometric altitude for true elevation gain and loss • No external hardware.

Terms of Use: https://dragracetimer.com/terms-of-use.html Privacy Policy: https://dragracetimer.com/privacy-policy.html Conditions data needs a network connection; without one the run still records, minus the conditions score. Note: GPS timing accuracy depends on signal quality and your device's sensors. Measure only where it is legal and safe — a private road or a closed track. Always obey local speed limits.
