I wasn t ready to go spend hundreds of dollars on a Dyno run So I went looking for a Dyno for my iPhone and I came across a PerfExpert PerfExpert was the first performance app I tried Their website has the information that was not included in the app for how to set it up and make it work It works so well for me that I didn t even go look for any other dynamometer apps I recommend this app for anyone that s interested                     Great car performance information Jdrasberry

I downloaded it to use for timed run but it is pratically hard to get it How to use It is not friendly There is app for android only which I wanted it is called Dino You setup the speed range like 50 150km h and when you reach the minimum speed it start recording automatically and ends when you get to 150             Timed run Luizvictorqueiroz

Did not contain my vehicle common truck DO NOT BUY     This app is awful JBrown62

Bad customer service App doesn t work at all Waste of money Doesn t even have all vechs in their system Would not give refund after asked over and over because their system doesn t have my vech Would not recommend this app to my worst enemy     If I could give a 0 I would Daddy sparrow

I tried with two different trucks and with the correct information and gear ratios the app read that I was going well over 140mph when I was really doing 60mph I tried with another truck that had a 6 55 gear ratio and the app complained that it was an unlikely ratio     Does not work at all gstubbz

I can plug the info that this app gave me into a 1 4 mile calculator and the trap speed which is the more accurate way to calculate power is only off by 2 5mph from what my car actually ran at the track I m impressed You need two things a phone with a good g sensor and you have to be able to plug in all the info the app asks for The less accurate your car statistics are the less accurate this app will be Happy I spent the money                     Pretty impressed Z31GOAT

Does not work as advertised nor does it work for automatic transmissions Waste of my money I want a refund                     Waste of money Beastk5
