This FREE app for the iPad, iPhone, or iPod seems to be popular.  The current version has 4 stars after 365 ratings. There are 75 pictures to color and it has some nice features –  it zooms in and out for small areas, it saves automatically, it’s easy to clear and start over, and it saves to the Photos library for sharing or to be used as wallpaper. The app also claims to develop eye-hand coordination. However, the only coloring tool within the app works like a paint can. Kids choose & touch a color, then choose & touch the area of the picture they want that color. The app does the rest as it color-fills that area. There is no possibility of coloring out of the lines so I am not sure of how much eye-hand coordination is involved. There is no possibility of making stripes, polka-dots, plaid, or any other fun design within an area so I am not sure how creative it is either. That being said, several people have commented that their kids like it and the price is certainly right 🙂
