    A very feature-full reading app. I use it with my PocketBook Color and PocketBook InkPad Color and it is much snappier than the default reading app.

    As an e-book reader it is unparalleled, I believe. It is not a feature-rich library management tool, though.

    Other than being an e-book store, it also allows PDF and EPUB files to be uploaded and they become available on all devices with Google Play Books. The reader is pretty great as well.

    Google Play books isn't an ePub reader. You need to buy books to use it.
