About Skitch

Skitch (by Evernote) is a smart little app for your Mac that you can use to write down, and explain inspirational images or documentsֲ when you're working on your idea. Using annotation, shapes, and sketches, your idea will get more body and you will be able to get the most out of all the inspiration you come across. Oh, and Skitch is free, in case you needed anymore convincing.
