Amazon is brilliant for developing an app to access its Kindle services on other devices. Adding this app gives you an alternative to iBooks. Once logging into your Amazon account, you have the ability to connect to the Kindle store. Of course you can purchase a copy of a book, but a free section also exists.

Once a book is wirelessly downloaded to your device, it remains on the app's built-in bookshelf. The reader has the ability to bookmark pages, and change the page color, layout, and text size. One can also search for a word or phrase that's within the book.

In my opinion, no device should be without this app.
