Latest reviews of TireMath app for iPhone and iPad

Worst app on the entire App Store
It instantly crashes every single time I open it, I want my money back for this piece of garbage.
Broken App.
This app does not load. It just crashes and still no update. I request a refund!.. Bu aplikasyon bozuk, yuklemiyor / calismiyor ve kapaniyor. Paramin iade edilmesini talep ediyorum.
The not function
The program not compatible is iOS 9.1 >
Great tool
The gear ratio tool is WAY......... off, but every thing looks to be right on, I have a 98 Jeep Wrangler. 27" Original diameter, 35" New diameter, current gear ratio 3.07, the app says 3.98 BUT every chart I found the gear ratio needed is 4.56, I actually have 33s and installed a 4.56 gear set, now in my rear end from a 3.07. Now I have the stock gear ratio feel and acceleration. Thats just my 2 cents, simple math might be there, but the friction and torque reduction is not factored
Quit working
Last program upgrade made the app not work. I can not change any of the numbers.
