Snapseed by Nik Software (Acquired by Google)
Snapseed is another award winning photo application for iOS. Snapseed's high ranking above other apps is largely attributed to its UI and the way it takes advantage of multi-touch gestures that are unique to the touchscreen interface. Without being limited to the exclusive use static buttons and tool bars, Snapseed relies on press, slide, and pull gestures to enact menu options and to apply filters and effects. The result is a unique iPad experience for augmenting photos that is unlike anything you will experience on apps that offer similar features. Snapseed, originally designed by Nik Software and launched in 2011, was purchased by Google
