User reviews

Great, but limits ratios

I love the visual representation of the gears! However I need a ratio far higher than 100. Above 100 it would most likely limit the graphical teeth drawn/shown, but it would allow to use the calculator without limits. Wish I knew this before I downloaded it.

Nice app, I want more though.

This is a great app, i wish it had more features though. for example: being able to type numbers into the box rather than being limited by the slider, being able to add more gears, change color of gears, fill the gears in with colors or patterns to be able to see better. also just more controls in general.
