Ratings and reviews

my 3 complaints: the app resets and forgets everything every day. so ive got to re-enter my tire size, 6 gear ratios, and axle ratio everytime. it won't allow a decimal in the tire size. my hight is 33.2" so I have to enter a incorrect axle ratio to correct the rpms. the rpm scrolling bar is so massively sensitive it takes for ever trying to hit the exact rpm you want to look at!!!!!!!!!

Simple and intuitive. It doesn't get any easier to calculate gearing than this!

This won't even launch 🤣 I just installed the latest version as of 10/29/2024 & it still doesn't launch.
