Sketchbook Mobile for iPhone

From the front page. Looks sweet.

Looks well implemented…but without a stylus and on a 3.5" display it seems like it’ll be more of a gimmick than a useful tool.

The lack of a stylus on the iPhone kind of makes these drawing apps like Advanced Finger-Painting.

I’m proud to say my buddy is actually the tester/designer of the interface for Sketchbook Mobile.
Once you get the hang of drawing with your finger and using the zoom in/zoom out feature a lot you can achieve some amazing results. He showed me what some people have done on it and it’s amazing.

Also works a million times better on the new iPod Touch and iPhone 3GS

You could also fork out for one of these…
