A new app has launched for the iPhone and iPod touch, iAPODViewer, which allows users to more easily access the NASA Astronomy Picture of the Day (APOD). The viewer offers an iPhone-optimized interface, with rotated and full-size image viewing -- for zooming and scrolling around -- as well as keyword searches, and the ability to save favorite APODs. The latter are stored in the iPhone's photo library for later recall. Each image features a description of the scene from an astronomer.

iAPODViewer is available at App Store, in both English and French, for $2.
