A sheet of paper, a 2B pencil and eraser. Fingerpainting kit for productive people (or not).

2B lets your iPhone double as an impromptu scribble pad whenever you 19re in the mood for analog. Sketch, scribble or jot in portrait or landscape mode, your image rotates along to maintain its original direction. App works even when you 19re offline and runs in fullscreen mode for maximum available drawing space.

You can only save one scribble locally (automatically loaded when you start up the app) but you can always take a screenshot of your scribble for more permanent storage on your iPhone/iPod Touch camera roll.
