GPS Race Timer vs Racebox

Measure acceleration times such as 0–60 mph, 60–120 mph and 1/4 mile directly with your iPhone — accurately and without extra hardware. The app is designed so it doesn’t need to be operated while driving; you just set everything up beforehand while stationary. Measurements then start automatically — when the target speed is reached or when a start is detected. You can save results locally on your iPhone and, if needed, export them or transfer them to other devices. Preset timers: 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, 100 – 200 km/h. All timers are, of course, fully adjustable. The free version measures up to two times per run. How to use the app: Check the timer settings on the start screen. If everything looks good, place your iPhone in the car where it has good GPS reception and is held securely, then start the acceleration test. You can adjust the timer configuration in the Settings screen (just tap the relevant timer). Then return to the race screen and follow the previous instruction. Optional PRO version (in-app purchase): 1. Up to four timers in parallel (instead of two) 2. Precise determination of elevation differences 3. Simulation of a Sportsman start and reaction-time measurement 4. No ad banners

Racebox companion app allows you to get detailed and precise results about your vehicle dynamics at 16Hz when paired with an external Racebox Bluetooth GPS device. The app will allow to: - Measure acceleration time from a standstill to a certain speed (0-60 km/h, 0-100 km/h, etc.) - Measure acceleration time from a standstill to a certain distance (60 ft, 1/4 mile, 1 mile, etc.) - Measure acceleration time in a certain speed range (80-120 km/h, 100-200 km/h, etc.) - Set up your custom metrics for speed and distance - Show your current driving data (altitude, heading, acceleration, road incline, precise speed, etc.) - Save VIDEO of your racing, follow onboarding instructions inside the app! All test runs are saved to the internal database allowing further sorting and filtering. For every test run the app keeps all necessary information for further analysis: - Detailed results for all metrics - Driving logs in CSV format - Result status based on road incline - Test run live map - Top speed and acceleration during the run Racebox app allows the creation of multiple user profiles for different vehicles. Select your preferred language inside the app. Export and share your test results! IMPORTANT: This app works only with Racebox devices (www.racebox.ru) and NOT with the iOS device's internal GPS.
