    ** Now with cloud support! **

    A free demo version is now available. See the end of this description for details.

    Calibre Companion (CC), recommended by calibre developers, is three applications in one:
    - a superb device-based calibre library organizer
    - a high-performance WiFi-based calibre device emulator
    - a calibre content server and cloud provider (Dropbox, Box, Google Drive, Microsoft OneDrive, and Amazon Cloud Drive) client

    1) CC is a device-based calibre library organizer. Once you put books on your device using one of the connection methods described below you can:
    - view a book's metadata (author, tags, series, rating, dates, etc.).
    - sort and group books by their metadata.
    - see book lists by cover or by list.
    - mark books read and sync this information with calibre.
    - launch your book reader application to read a book (works with most reader applications except for Amazon Kindle for Android on non-Fire devices).

    2) CC can connect to calibre over WiFi and be detected by calibre as a device. Once connected, you use calibre to move books to and from your device. Calibre automatically updates all the book metadata stored by CC to match the latest in your library.

    3) CC can connect to calibre’s content server or to your cloud provider to browse your library and download books to your device. Cloud providers currently supported: Dropbox, Box, Microsoft OneDrive, and calibre libraries on the device or on an SD card.

    For more information see our FAQ (

    1) CC is not a reader app. You must install and use one of the many excellent reader apps available.
    2) CC requires that you use calibre calibre 0.9.02 or later, available at Some CC features such as syncing book read information require newer versions of calibre.

    A free demo version of CC is available in the Google Play store. Install and test with that version if you have concerns that CC won't work on your network or isn't what you need. To get it, go to and click the button for the demo version (links to Google Play don't work here).

    Permissions explanation:
    - Allow Wi-Fi multicast reception: multicast is required to be able to find calibre without requiring you to enter an IP address.
    - Users with Jellybean (Android 4.1): You will also see a permission about “Test access to protected storage”. This is caused by a change Android is making regarding SD card access, and simply means our app can save books on your external storage.

    Nice app but more update needed. Especially it doesn't show book details like format & size information for books in cloud. You have to download the book to get all information. And there is no format based sorting option!! Pls fix this.

    Loving the app. But it need a easier way to update a downloaded file. It wont update/rewrite the earlier file that I downloaded into my device. A hassle for multi-chaptered online stories.

    Won't let me select folders in OneDrive Edit: Copying the metadata.db file to the OneDrive folder containing my ebooks fixes the problem.
