Perfectly Clear is a photo autocorrection app. Previously only for iOS devices, it's now available for Android. It has been reengineered for better performance on Android devices allowing it to run faster than the iOS version.
The app also has a new interface for better workflow, the capability to correct multiple photos at once, preset corrections for specific problems, and some beauty enhancements for portraits.
After take a picture or pick one or several photos from your library, Perfectly Clear goes to work. A slider overlaid on your picture lets you see before and after just by sliding it back and forth. If default "fix" didn't get the results you want, there are several other presets along the bottom to try.
