GPS Race Timer
Measure drag race times
Free · In‑App Purchases
With GPS Race Timer you can measure the acceleration times of your vehicle.
The app supports drag races such as 1/4 mile races or speed-based races such as 100 - 200 km/h and can measure up to two times per race.
The app is designed so that it does not have to be operated while driving, everything can be set up in standstill.
The measurements are then performed automatically.
You can save the race results locally on your phone for later access.
The predefined timer settings are: 60 ft, 1/8 mile, 1/4 mile, 1/2 mile, 1 mile, 0 - 60 mph, 0 - 120 mph, 50 - 75 mph, 60 - 120 mph, 0 - 100 km/h, 0 - 200 km/h, 80 - 120 km/h and 100 - 200 km/h, but you can also adjust these timers to your needs.
How to use the app:
Check the timer settings on the start screen. If they are okay, place your phone in your car so that it has good GPS reception and does not move too much, then you can start the acceleration test.
You can adjust the timer configuration in the settings screen. Then go back to the race screen and follow the instructions above.
The optional PRO version which can be purchased in the app comes with the following benefits:
1. Up to four timers in parallel (instead of two).
2. Accurate determination of altitude differences
3. Simulation of Sportsman Start and reaction time measurement
4. No ad banners anymore
This update improves sensitivity when detecting race starts from a standstill and includes general bug fixes.
Additionally, we've introduced an optional PRO version that allows up to four parallel timers, accurately measures altitude differences, adds a Sportsman start simulator with reaction-time measurement, and removes all ads.
