Do you have photos on your phone that need a little 'help' without going back to your Mac for iPhoto clean up or Photoshop work? It happens to me all the time, and TouchRetouch for US$0.99 gives you some powerful tools to remove defects, people or objects from photos with only a little effort. It is especially nice when you are on an outing or vacation and want to get some photos emailed to friends or uploaded to a sharing site, but the photos aren't as perfect as you would like.
TouchRetouch lets you load an image from your camera roll, and using your fingers, either draw a lasso around the offending part of the photo or use a brush to highlight it. Using some smart software, the object or person will be removed, while the background is intelligently filled in. It's similar to Content Aware Fill on the new Photoshop CS5, but this app costs a lot less money. The software has unlimited undo, and you can erase all or portions of the mask that you create. When you're done, you can save the photo back to your camera roll or email it directly from within the app. The app also supports sharing on Facebook, Flickr, Picasa and Twitter
TouchRetouch has built-in video tutorials and a clone tool to repair parts of an image that the retouching process doesn't fix perfectly.
