Pixel Winch

Pixel Winch is a screen measurement app with a unique approach. Rather than overlaying complicated controls on top of your existing workflow, it combines aspects of a traditional image editor with the quick access of a modal interface (similar to OS X's Launchpad or Dashboard).

Select a region on the screen to load it inside of Pixel Winch. The captured region will automatically magnify and center on your display. Take measurements using any combination of the included tools. When finished, simply press escape to dismiss Pixel Winch.

Need to look up previous measurements? No problem -- use the history list to revisit past images. Worried about images clogging up your hard drive? Pixel Winch can be configured to automatically delete them.
