there are plenty of free drawing apps that run circles around this one. try sketchbook express/sketchbook pro. this tool has no line weight options, very few tools, a really weird eraser that doesn't erase in real time. there's no undo... bleh.

Most free apps have more functionality than this. Please add colors, shapes, zoom, and pen size as a bare minimum to be a paid app.

Nice simple and simple. The line tool is great. Wish you could change the canvas/paper size and zoom out or pan.
