TrakStats is a performance measurement tool for automotive enthusiasts. TrakStats combines GPS and sensor data from your phone to accurately approximate key performance metrics used to benchmark performance vehicles on closed course tracks.

Other available measurement devices and tools can cost hundreds of dollars or more and don't provide the level of customizability that TrakStats does.

So Inaccurate it’s worthless

I followed all the instructions. Good mount, smooth surface, good GPS etc. On back to back similar runs one said 0-60 in 3.1 and the next 7.1. I don’t think GPS refresh rate is fast enough to be accurate.

Never a true reading

Once it told me Something like 27Gs on a motorcycle and 250mph speed lol.. gps signal - always poor... any place

Developer Response ,

Hi Svani13, did you have the phone rigidly mounted and positioned according to the info popup? Have you tried resetting your location and privacy settings under General>Reset>Reset Location & Privacy? We have had some users report issues with GPS signal that were resolved by performing this reset
