If u Remember few days back Photoshop.com app was released for iPhone and iPod Touch (Pictorial Review) which was a hit as per features and was available for free.
This App allows Android users to Edit Pictures using touch interface and also allows you to back up all your Photos online, to Photoshop.com.
The Editing interface is same as the iPhone interface, and this app is available on the Android app store so if your on a Android, get it now!
