What is Calibre Companion?
Calibre Companion is three applications in one: a superb device-based calibre library organizer, a high-performance WiFi-based calibre device emulator, and a client to access your calibre library using calibre's content server or in the cloud: [Android and iOS]: Dropbox, Microsoft OneDrive; [Android]: Box, Amazon Cloud Drive, Google Drive (
warning about Google Drive).
CC DOES NOT INCLUDE A READER APP
- The first: CC is a calibre library organizer for your device.

- Calibre Companion updates the metadata for the books on every connect as a wireless device, ensuring the information for your books displayed in Calibre Companion is the same as the information displayed in calibre.
- Most setup is on the device, making it easy for different users in the same household to have different device configurations, or to use more than one computer running calibre.
- The third: Calibre Companion can access your library via calibre’s content server or the cloud.
Using just your device, you can:- Browse all of your library, viewing the books and their metadata.

- Download books from your library to your device.
- Cloud providers currently supported: [Android and iOS] Dropbox and Microsoft OneDrive. [Android] Box, Amazon Cloud Drive, Google Drive, and a local folder on SD card.
Notes:
- You must also already use calibre to manage your library of ebooks. CC gets books only from calibre.
- By default, CC imports the book file (and its metadata) into your device. If you don’t have much storage on your device, it is recommended that you use CC as a catalogue/database instead or only import the few that you are going to read soon. This is particularly recommended for users with comics, which tend to have very large book files.
