Bought this this morning. I'm a figurative artist, for over 30 years, and this is a very nice tool. Especially for a version 1.0. The stroke dynamics are very good, and I'm running this on a first generation iPad. I've been sketching with it off and on all day, and have really grown to like it.<p>Things it needs:<p>* Pinch zoom in and out. Gotta have this. It works great when you are drawing at the scale of the whole page, but detail work suffers as the sampling of the device isn't good enough. (Nor are my fingers! This is why artists and illustrators often draw and paint as large as possible.) When they add zooming, and they say on their website they are, they need to be sure and adjust the tool's scaling to match the view.<p>* The limited color palette is fine, but I need to be able to pick the colors.<p>* More tools are a given, especially since the program itself is free and they are making their money by selling extra tools. I've already plunked down my eight bucks for all that's available.<p>The minimalist interface is fantastic. When you are drawing, and I'm speaking as a person who draws observationally, you want the tool to be as spacial and object oriented as possible. This doesn't mean you have to mimic "real world" drawing tools, but it <i>does</i> mean that the interface needs to not emphasize numerics and linguistics. The organization needs to be <i>very</i> simple; from a drawing point of view, if I have to drill down through a series of hierarchies I might has well type in menu selections from a command line. My attention needs to be on my subject and my drawing, not on a UI.<p>YMMV.
