Very good app!! It's amazing how accurate this app is once set up correctly. It took me a while to figure it all out but this app is brilliant. Amazing that a phone can produce hp results like this. Tested on a mini cooper with 115bhp results showed in third gear 115.5bhp.😀
fail! app doesnt work properly. did everything it asked and it would not log any data at all. i can get it to go to yellow if i turn my car off, turn it on and vibration makes it go green then i go and bang through the gears then it just resets to black lights and gives me no data. NEED START AND STOP BUTTON TO ENSURE A GOOD READING! DELETING THIS FAIL.
Never worked Useless... no info gets recorded. Takes forever to be ready. Having a button to make it ready and go would make it much better
Damned if I can get it to work w/Nexus 4 Android 4.4.4 & 400rwhp car Can't get the green light (or any light at all) to stay on. Tried a few different locations with the same results. Tried 4 0-100 runs, it did nothing. It doesn't seem to pick up acceleration for me at all - and my car does better than 5 seconds to 100. Checked the accelerometers and location services, all working OK. All this app does for me is drain my battery.
For the people who say it doesn't work either you drive a little civic rice burner or has an old phone or both.
Doesn't work won't record times
