I've tried other Ipad drawing apps (Sketchbook, ArtRage, Brushes). They all seemed to have something clunky about their design, and I never got used to finger-painting. Finally I found a great combo of tools: ArtStudio for Ipad and a Logiix Stylus Pro stylus.
ArtStudio costs just $3 and I can't say enough great things about it. It's fast, easy to learn, comes with a 45-page manual of tips, and is jam-packed with more features than you can shake a stick at. Its logical layout allows you to draw with one hand and use the simple sidebar menu with the other to swap tools, pick colours, and undo commands. The online artwork being generated with this app doesn't do it justice. ArtStudio is a high-performance program at a bargain price.
