SpeedGPS: Track Your Speed & Optimize Performance

Car speedometers are built to read high - never low. SpeedGPS shows you the real number.
It turns your iPhone into a precision GPS speedometer and acceleration timer: standing starts, rolling pulls, top speed - every run saved to the car that did it.

MEASURE
. Standing start:
. 0 - 50 km/h (0 - 30 mph)
. 0 - 100 km/h (0 - 60 mph)
. 0 - 200 km/h (0 - 120 mph)
. 0 - 250 km/h (0 - 155 mph)

. 200 - 300 km/h (120 - 180 mph)

. Live speedometer with top speed, average, distance and elapsed time
. Works in portrait and landscape

WHY THE TIMES ARE HONEST
GPS delivers about one fix per second. That is nowhere near enough to time a 0-100 run properly, so SpeedGPS interpolates between fixes and reports every split to a tenth of a second instead of rounding to the nearest whole one.

EVERY DRIVE, KEPT
Each run is stored with its route on the map, elevation profile, speed curve and the weather you drove it in. Compare drives, star your best ones, watch the numbers come down.

YOUR GARAGE
Add your car with the detail that actually matters: engine and drivetrain, power and torque, weight and balance, dimensions, wheel and brake setup, hardware and software. Log service work, modifications and a full mileage history. Set a car active and every drive files itself against it.

RECORDS
Twelve acceleration records, all-time top speed, best five-minute average, total distance measured, highest altitude reached. One board that tells you exactly where you stand.

ALSO INSIDE
Performance calculators, parking timer, km/h or mph, °C or °F - metric or imperial throughout.

FREE, WITH AN OPTIONAL UPGRADE
SpeedGPS is free to use with ads. SpeedGPS Pro removes every ad and unlocks:
. 5 cars in the garage instead of 1
. Satellite, Hybrid and 3D maps, plus routing with distance and ETA
. Hourly weather forecast, saved with each drive
. Alternative app icons and priority support

SAFETY FIRST - DO NOT OPERATE WHILE DRIVING
Only use the app when the vehicle is stationary. Never run tests on public roads or anywhere not intended for them, and always obey local speed limits. We accept no liability for errors, damage or accidents arising from use of the app.
