*edit// I still use this as my go-to free gear ratio tool. Ken updated to 10 ratios shortly after the suggestion which was super awesome!! I'm very pleased with these guys. Since the additional gear slots seem to be a simple change, would 20 ratio slots be possible? I bet Truckers looking to build custom powertrains could benefit from this App too.

The updated version (0.0.6) now supports up to 10 gear entries. Thank you for the suggestion! Ken

I love this app, but it needs the option to save gear sets and name them for each vehicle we choose so I don't have to look up the gear ratios every time. Otherwise, very accurate.

Hey developer, can you add an option where we can find the gear ratios based on the input speed (more like vice versa). I'm not sure if it's possible but it's going to be helpful!
