    Google Play Books vs calibre opinions
    Some users think Google Play Books is a great alternative to calibre, some don't.

    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.

    Allows epub-format books to be uploaded, at which point they become available on all devices you have GPB installed on. I use this for all my public-domain (Gutenberg, Azora-bunko, etc) ebook reading.

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

    I use the web-based platform and it's just very good. Super intuitive and minimalistic but with great functionalities and customization. And it's FOSS.
