Keep your calibre library organized on your Android phone or tablet. Browse book covers and details, find your next read, and open books in your preferred reader app.

YOUR LIBRARY, ORGANIZED
• View authors, series, tags, ratings, and other book details.
• Sort, search, and group your collection.
• Switch between cover and list views, with light and night display options.
• Mark books as read and sync reading status with desktop calibre.

CONNECT TO DESKTOP CALIBRE
Connect as a wireless device over Wi-Fi, then use calibre on your computer to send books and update their metadata. You can also browse your calibre Content Server and download books directly to your device.

ACCESS YOUR CLOUD LIBRARY
Browse a complete calibre library stored in Dropbox or Box and download books for use on your device. Cloud libraries must include the metadata.db file and their book folders. A folder containing only ebook files is not a complete calibre library.

OPTIONAL AI PLUS
Ask questions about a book, choose chapters to use as context, and review AI suggestions for its metadata. AI Plus requires Google sign-in, an internet connection and a separate subscription with usage credits. Credit costs are shown before a request. Selected book text and questions are sent to our AI service for processing. AI responses may be inaccurate; review suggestions before applying them. AI Plus and ad removal are separate purchases.

FREE LIBRARY FEATURES, OPTIONAL AD REMOVAL
Library organization and supported connections are available without an ad-removal purchase. The free experience includes banner ads in the library. Choose an optional monthly or annual ad-free subscription, or a one-time purchase for permanent ad removal. Current prices are shown in the app and confirmed by Google Play before purchase.

Subscriptions renew automatically unless canceled through Google Play. Canceling stops the next renewal; ad-free access continues until the paid period ends. You can restore eligible ad-removal purchases using the same Google Play account. Previous purchases of the paid app do not automatically enroll you in a subscription or result in new charges. Ad removal is a separate optional purchase.

BEFORE YOU START
Calibre Companion is a library manager, not an ebook reader or file converter. Install a compatible reader app to open your books; supported formats depend on that reader. Books and a desktop calibre library are not included.

Wireless device and Content Server connections require the corresponding service to be enabled in desktop calibre and a network connection between your devices. Cloud access requires your own account and a complete calibre library uploaded to that provider.
