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 (web access) 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).

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. No other app, reader or browser, offers this level of integration with calibre.

3) CC can connect to calibre’s content server over WiFi to browse your library and download books to your device.

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 version of CC is available in the Google Play store. It is fully functional but limited to 20 books on the device. If you have concerns that CC won't work on your network or isn't what you need, install and test the free version. To get it, go to and click the button for the demo version (links to Google Play don't work here).

    Calibre Companion is the best reason to switch from iOS to Android. Well done!

    I have used CC since its first appearance in the Play store. Loved it then. Love it more with each update. Current wish: real time update, eg when changing Read to Yes, without having to bounce out to Connect; I would like to simply give CC permission to connect whenever it needs to.
