GPS Race Timer vs Ride Forces

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

Ride Forces records g-forces on roller coasters and amusement park rides with your iPhone or Apple Watch. View graphs, analyze stats, and share the forces of your favorite rides. A must have app for thrill seekers, roller coaster enthusiast, and physics nerds. Standard Recording: Captures the g-forces of rides and roller coasters. Provides stats and graphs of g-forces in three dimensions. - Records force data from accelerometer - Requires motion tracking permissions Subscribe to Ride Forces Pro to capture advanced recordings. Advanced Recording: In addition to capturing the force data of a standard recording advanced recording captures rider orientation, GPS data, and weather conditions. This reveals additional ride information including: identifying airtime/hangtime, inversions, orientation angles, a map of ride location, temperature, wind speed, and wind direction. A Ride Forces Pro subscription is required to capture advanced recordings. Advanced recordings can be viewed, edited, and shared with or without a subscription. - Records force and orientation data using multiple sensors including accelerometer and gyroscope - Records GPS data - Records weather conditions (requires internet connection) - Requires location and motion tracking permissions - Records for a maximum of 15 minutes - Advanced recording will fallback to standard recording if the app is closed while recording Privacy Policy: https://rideforces.com/privacy/ Terms of Use: https://rideforces.com/terms/
