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.

CC has been translated into the following languages:
  Portuguese (Brazilian): 100% translated
  Italian (Italy): 93% translated
  Spanish (Spain): 72% translated
  German (Germany): 51% translated
  Japanese (Japan): 55% translated
  French (France): 47% translated
  Russian (Russia): 27% translated

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).

    If you have the Calibre ebook management application, and an Android tablet, then you need Calibre Companion. It is, quite simply, the easiest and fastest way of transferring files and updating metadata. There are other ways of doing this, but having experimented with them, CC is by far to be preferred. As a library, it is quick and slick, and with the ability to assign specific book readers to sp

    Love it. Have Calibre set to run automatically at a set time daily, so sync'ing news recipes to my Nexux 7 with CC could not be easier or more reliable! (I wish I could got post a review of the demo app, but it has to be installed at the time...)

    Very good app for grabbing books from my calibre server. My only gripe is it requires wifi to be on. I can't grab books on to my phone when I'm on my mobile network. I don't understand why they limit this...

    TotalIy worthless to me of course. It requires a newer version of the Calibre server than I have. I can't update that because it is a packaged version that runs on my Synology NAS. Too bad the developer won't support backward compatibility.
