Measure your car’s acceleration times without extra hardware: 0–60 mph, 60–120 mph, 1/4 mile and more – automatically.
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
Downloaded the app just for fun to see how accurate it was. Did several quarter mile pulls. The 0-60 times seemed to be accurate. The GPS does a decent job of tracking speed. The 1/4 mile times seemed to be off by a significant margin though. My car should do a quarter mile around 15 seconds. The app is suggesting that my near bone stock civic si is a 12 second car. Not a chance. Had 100% GPS signal the whole time. If you want a decent 0-60 timer this will work well, but don’t rely on this app for super accurate quarter mile times. Overall, it exceeded my expectations as it is a GPS tracker and not an OBD2 connection so you can only expect less than perfect results.

Must say that this is one of the best gps race time recording apps that I’ve seen definitely seen. Only problem with any of these apps is that they will only give an estimated 0-60 but definitely a good app that has some potential for the future.
Performance Testing

This app provides standard testing like 1/4 mile time and speed, 0 to 60, 0 to 80 time etc.It can start timing when you start to move, I like that.One thing I really like is the ability to set settings for different “passing” speeds.Like maybe you want to know time testing starting 10 mph finish at 70 mph, there are user setting available.I like the app a lot!!!
Worthless

Half of the time the timer never even starts. The results I get are so sporadic I wouldn’t trust them. My 2016 charger hemi should be in the 5.5 ish second range for 0-60. Sometimes it says 8 or 10 or nothing then says I did a 12 second quarter mile. Anyone who knows anything about drag time knows those two times don’t add up. I ran about 20 times and twice got a 5.9 which should be in the ballpark. It doesn’t correct the time if the GPS lags either, despite what the developer says in all their replies to negative comments.
This update improves measurement quality and usability: optimized GPS accuracy, higher performance/stability, and includes a new tips pop-up.
