Nothing special really. You can customize them more (colors, handwriting, and other stuff) since I'm doing it on my iphone so it is all touch screen (literally doing it by hand ). If I do it on my ipad, I'll probably have a better one. If you actually like it, I'll download the app on my ipad as well.

EDIT: forgot to flip them oh well, already deleted them from my comp =/ Stupid me. It'll be right for the real one if you want my low quality stuff.
