description

A simple drawing app for the iPhone and iPod Touch. It aims to make drawing on a small touchscreen feel natural, by reducing complexity and interrupting the user as little as possible.

The tactics employed include: reducing number of menus to a bare minimum, using the speed of one's gesture as a substitute for pressure, applying time-based effects to the marks made on screen, allowing overlapping marks to take on new qualities, and offering a tightly edited set of tools.
