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. No subscription to start.

CLEAN DATA, NO JUNK RUNS
• False starts detected and discarded automatically
• Runs that never really left the line are dropped, not saved
• Live GPS accuracy warnings before and during a run
• Every metric explains itself — tap any stat for a plain-English definition

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.
