Is there an app where you can draw on photos in your library? And if so, what's it called?
You Doodle is free and is pretty awesome - http://appstore.com/youdoodle
ArtStudio is very nice.
You should try flip it. You can upload images and draw on them and stuff if that what you mean. You can also make cartoons. Lol it's fun!
Art Studio Lite or Glow Magic.
