Barnes & Noble today introduced a Nook app for Android. It is the only Android e-reader app that allows readers to share e-books with friends. The company also announced that it will soon be rolling out updates of Nook for iPhone, Nook for iPad, and other e-reading apps in the coming months.

Using Nook for Android, customers with Android OS 1.6 and higher can shop and download titles from the retailer’s e-bookstore. A customer’s personal Barnes & Noble e-book library--purchased on a Nook, at or on another e-reader--will sync to their device so their library is always available.

Some of the new app’s features include the ability to customize text with font styles and sizes, a navigation bar, reading in landscape and portrait modes, and graphical page turns. Its LendMe feature lets customers share “eligible” e-books with friends for up to 14 days, for use on the Nook, iPad, iPhone, iPod touch, or a PC enabled with free BN e-reader software.

Barnes & v-p of digital products Douglas Gottlieb said Nook for Android represents “the most-requested version of our free e-reading software to the growing number of mobile customers using Android-based devices.”
