Doodle Book – Drawing Pad

—1— There aren’t very many colors, unless you know how to use the sliding things to make any color (good luck)..—2— Cannot enlarge picture to color in cleaner lines. Pretty much impossible with your finger only. —3— The undo button undoes large unpredictable chunks of your work. Then there is no redo button.

I tried it out and it's the same like all of the others. I cannot give it 5 stars. The annoying ad isn't going to make this app worth rating. Sorry.
