This little iPhone/iPod app is a must have for every artist. SketchBook Mobile, by Autodesk, is a drawing application that allows you to draw with your fingers on your iPhone or iPod Touch. The app is full of features and will not disappoint you. The best part is Autodesk has a lite version, SketchBook MobileX, that will let you explore before purchasing the full version.
Pros: Great touch interface, lots of options, and easy to use
Cons: I wish the canvas output was larger, I want a bigger screen – maybe Apple will release the rumored “iPad” this winter
