iGearbox

This app hangs up when you try to use dropbox. Then I have to remove it and reinstall it. Please fix.

I wish that there were more options when building a gear train, like the ability to have a rotating arm instead of fixed axial rotation. This addition would greatly increase the versatility of the app. The planetary gear animation is nice to get a basic understanding of the motion, but I would like the ability to add more planets to the system!

I really love the way it helps you understand how the planetary or regular gearbox work. Very handy and useful to find the ratio of a gear set with just simply touching and building the gear set in few seconds.. I love the animation of the planetary gearbox!
