PhotoSweeper 2.0
Smartphones make it a little too easy to take a ton of photos. My biggest problem is that I take too many shots of the same photo without ever going back and picking the best one. PhotoSweeper 2.0's aim is to help fix that problem. It can scan your library and group similar ones together so that you can eliminate the ones where your eyes are closed or someone isn't smiling. It supports iPhoto, Aperture, Adobe Lightroom, as well as folder based image libraries.
