📝 About this app

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

1) CC is a device-based calibre library organiser. 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

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. Supports Dropbox and Microsoft OneDrive.

Privacy Policy: http://faq.calibrecompanion.co/index.php?solution_id=1077
Terms of Service: https://calibrecompanion.co/terms-of-service/

Notes: CC is not a reader app. You must install and use one of the many excellent reader apps available. You must also already use calibre to manage your library of ebooks.

This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
