I love the concept and couldnt wait to color a page and bring it to life with my soon to be 4 year old. The first page we colored after opening the app found out it was going to cost 4.99 to turn into 3D. So we printed off one that said free, colored it, and brought it to life. It was neat but I wish you didnt have to hold the phone over the picture the entire time. Wish there was a way for it to save it to your phone so your kid could play with it away from the coloring page.
