Pattern Blocks Manipulative

My 9 & 13 yr olds sat and played with the app for quite a while. While real pattern blocks are preferred this app will be a good addition for those times we are not at home, need to wait for a sibling, etc. Plus: while you might run out of space to place blocks you won't run out of your needed shape! Rotating the figures was a little frustrating and it will be interesting to see how the 5 yr old copes with that.

The shapes do not fit together like actual pattern blocks should. Two white rhombus would usually make a perfect 60 degree angle that would fit a triangle or blue rhombus perfectly. They do not, and this makes it very difficult to piece them together. It is very disappointing, given that you have to pay for this app.

I get very frustrated trying to rotate pieces....I don't feel this is very responsive. There are times I would tap repeatedly and nothing would happen. I would like to see the ability to move the entire design

I want the pattern blocks to be the typical primary colors. I don't like that the new colors don't match what I have in my classroom. Could you give us the option to choose the primary colors or these new ones?

This is intuitive for virtually manipulating shapes. It would be better, however, if you we're able to print, email, or otherwise share creations.
