Amazon said today it is launching a free Kindle app for the new HP TouchPad coming out this summer.

Amazon said its Kindle app for the TouchPad will gives users access to more than 810,000 titles from its Kindle store.

“When you buy a Kindle book, you can already read it on Kindle and our free ‘Buy Once, Read Everywhere’ apps for iPad, iPhone, iPod touch, PC, Mac, BlackBerry, Windows Phone 7, and Android-based devices, so you never have to worry about what to do with your books if you change devices or platforms,” said Dorothy Nicholls, Director, Amazon Kindle.

“We’re very excited to add webOS to this list. As with our other Kindle apps, the webOS app will be free and will incorporate our Whispersync technology so you can seamlessly switch between devices and platforms and never be without your reading.”
