    Calibre is for PC, Moon+ Reader is for Android. They are great as counterparts and I use both regularly, but neither is an alternative to the other.

    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.
