😟 does not work with iOS 11

Needs update for 64bit iOS 11. Can’t open it anymore. Old review below, used to be a 5 Star app!

We have three kids racing bmx and cyclocross while dad races, well, everything. This is great for quickly comparing gear options with our limited chainring and cog options over different wheel sizes. Easy to use, intuitive, and looks nice. Well done!


Wicked Good!

Beautiful and properly laid out user interface, incredibly intuitive to use, covers every chainring/cog/wheel combination you are likely to ever need and fully customizable to your personal setups. The calculations are simple but this app makes it really fast, fun, and easy to explain gearing options.

One of the best apps I've ever used!

Bike tester

Nice car but out of date

This is a nice app with about all you'd want. Issue is with today's 1x11 drive chains, the gear choices are evolving. The app won't let you use more than a 42T large sprocket. App needs to be updated to go on up to 50T. Maybe beyond.
