Amazon.com today announced that Android users soon will enjoy the Kindle App on their devices. According to a press release, the free application is coming this summer.

Kindle for Android will include Amazon’s Whispersync technology, which saves and synchronizes a customer’s bookmarks across their Kindle, Kindle DX, iPhone, iPod touch, iPad, PC, Mac, BlackBerry and, soon, Android, so customers always have their reading material with them and never lose their place.

“We think customers are going to love the convenience and simplicity of having instant access to a massive selection of books from Amazon on their Droid, Nexus, Incredible and many more Android devices,” said Jay Marine, director, Amazon Kindle.

Amazon has seen pressure recently from competing devices like the Barnes & Noble Nook and Apple’s iPad. According to DigiTimes, the Nook outsold the Kindle in the month of March.
