Great app especially for multi-geared riders

I really love this app and all the nifty functions that it offers. You can create custom charts of your multi-geared drivetrain that will give you an idea of the various ratios your bike has. I would recommend this to novice riders as it is very easy to illustrate how the desired gear ratio can be replicated without having to engage the “big-big” or “small-small” combo.

A couple of suggestions to improve this app:

1. Add an extra digit after the decimal to the gear ratio displayed in the chart table

2. Add skid patch calculation on the home screen (bonus if it offers ambidextrous skidding). This would make the app attractive for fixie riders too

Works perfect to calculate gear changes

Very happy with how this app works. I use it to calculate gear changes with advanced modern 1x drivetrains as well as how tire size effects gear range with all the tire width changes like wider modern bikes that are all road and gravel bikes.
