Normally I don't talk about apps that don't run on both Windows and Mac but this little $7.99 Mac app that was updated to version 2.0 yesterday is so cool I can't resist. The app is called Snapheal 2.0 by Macphun.com.
Snapheal 2.0 will remove home owners cars from the driveway, junk from the yard, dishes from the sink, all those photos and kids drawings from the fridge in a snap. Sure you can do it with Photoshop but this little app feels like the whole process goes faster than cloning. You just paint over the object you want to remove and bam, it's gone.
The other thing I like is it supports the Retina display on the new MacBook Pro.
