Great Thing but
where is the Export-Button???
where is the Export-Button???
amazing!
This app is so cool! On one level its just fun to look at the shapes, spin them, slowly Unfold them, spin them while half-Unfolded … but then its also handy because I was never quite clear on just what a dodecahedron looks like. And who knew there were rhombicuboctahedrons out there? Now I have to show this to my daughters math teachers! One more thing: what a cool tool bar! I was thinking that the UI was nice, simple, and to the point, and then I started rotating it … nice touch!

Missing core shapes
Was hoping to use this with my seven year old and was disappointed to see that it was missing so many of the solids he needs to learn about. Where is the pyramid, cylinder, rectangular prism, and triangular prism?

A really useful tool
I teach 7th grade math, and one of the concepts that students really struggle with at that age is trying to picture what a prism looks like when it is Unfolded. I like how this app allows you to rotate the shapes so you can see them in different orientations and also how you can pause and reverse the folding and Unfolding. The only change Id like to see is the ability to change the dimensions of the rectangular prism. My students have to be able to construct nets with dimensions other than 1x1x1. Having this change would definitely make this a 5 star app!

Not enough basic solids
Not what I expected. Seemed limited in some of the basic ones.
