Needs a few things
I bought this app for my iPad and loved it. It was a bit crashy, but mostly worked. It wouldnt crash completely, just to the background. So, naturally, I didnt install it on my iPhone 3. When I got my iPhone 4, I added it right away. Ive found it to be hard to precisely color on such a small screen. Im not attempting shading or anything but tapping on a tiny hoof colors the whole background, tapping on a stripe in the horns colors the section you already colored. Plus, if you mess up, no undo.
So, I recommend a zoom option (finger pinch) and an undo button. 5 stars for those options.
