I used it to figure out which rear end to put in my car. By setting the axle ratio to the ones I wanted to use I was able to see what my rpm would be with that ratio. I definitely recommend this app!!!
Very useful apps
I dont have a tach and its fun to see what my RPM is without a tach. Just had to look up my gearing on the net, measure my tires and wala, I had a tach!
This app is AWESOME!!! Its dead on accurate. Ive tested it on two vehicles that have a tach and its right on. I just measured my tire height, looked up my overdrive trans ratio, and entered my rear end gears and boom instant tach. I used it on my Ford Ranger that doesnt have a tach to determine what rearend gear would be best suited for the speed that I drive at. Saved a lot if time and trial and error. Definatly highly recommended!!!!
I was glad to find this app, but it when I click on the app after downloading. It wont even open. It crashes instantly. I dont think it is comparable with IOS 9 or later.
