FlySketch

FlySketch is a screen capture and drawing program, but like none you have ever used before. FlySketch floats above all other applications and allows you to take screen captures, annotate, highlight, and markup your image. Use workflow actions to send your creation across the Internet in an email, or to a folder on your desktop. Or use the built in drawing tools to make your own diagrams or creations.

Version 1.7.1:

• It's now free!
• FlySketch now requires OS X 10.6 or later.
• Fixed a bug where FlySketch couldn't take screenshots on OS X 10.7.

Requirements
