Sketchy

The Sketchy app allows you to quickly sketch up drawings by tracing your finger over the screen. You can create single or multiple pages per sketch, and these can be save or reloaded at any time. As well as drawing lines, Sketchy allows you to create with a number of shapes. Lines and shapes can be of different colors and line thicknesses, and the shapes can be color filled. Sketchy works in either portrait or landscape mode. Lines and shapes may be repositioned after being drawn, and drawing items can be undone or redone as required.
