Barnes & Noble has introduced Nook for Android. This comes in the form of a free app that lets users read eBooks with customizable font styles. The company says this is the first Android eReader app that lets users share eBooks with friends.

The company also points out that this is the first eReader software to feature its new "NOOK-centric" branding. The app will soon be followed up with updated apps for the iPhone, iPad, and other devices.

"NOOK for Android is customizable, fun and easy to use and we’re excited to deliver the most-requested version of our free eReading software to the growing number of mobile customers using Android-based devices," said Douglas Gottlieb, Vice President, Digital Products for Barnes & Noble.com. "Android customers can enjoy the great NOOK eReading experience on their mobile device, including access to our vast digital catalog and their personal B&N digital library at their finger tips. And, of course, Android users can now enjoy Barnes & Noble’s unique eBook lending feature to share their favorite eBooks with friends."

"With NOOK for Android, and the other renamed software to follow, customers can also easily recognize and have confidence in Barnes & Noble’s NOOK brand to provide them with a fun and easy-to-use eReading experience on any device of their choosing," he says.

The new Nook app is available for Android versions 1.6 and higher. It can be downloaded from the Android Market.
