About Calibre-Web-Companion

Unofficial companion app for Calibre-Web and Calibre-Web Automated. Browse your book collection and manage your digital library on the go.

Built with Flutter and Material You for a modern, intuitive and responsive experience. Available for Android, in 15 languages.

Features:

- Connect to your Calibre-Web (Automated) server, including reverse-proxy / SSO setups, custom HTTP headers and self-signed certificates.
- Browse your whole library and discover books by author, series, publisher, rating, hot & trending, and more.
- View rich details for every book, edit its metadata, and upload new covers.
- Mark books as read or unread, archive them, and organize them into shelves.
- Create, edit and browse Magic Shelves: dynamic, rule-based shelves (Calibre-Web Automated only).
- Add books quickly by scanning their ISBN barcode.
- Read books in the built-in eBook reader and sync your reading progress across devices via WebDAV.
- Send books to your e-reader (Kindle/Kobo) via BookDrop or Calibre-Web's email function.
- Download books into your collection with Shelfmark. This app does not support or encourage the piracy of copyrighted works; please only download content you are legally entitled to.
- Upload books to your server, and sync your whole library or selected books for offline reading.
- Make it yours: reorder or hide book actions and sections, choose a theme, enable e-ink mode, and adjust the text size.

The app is in active development. You can open issues on GitHub for bugs, feedback and feature ideas.

What's Changed
Feat: Set bookmarks in the internal reader (EPUB, PDF and CBZ) and jump back to them; they sync between devices via WebDAV
Fix: EPUB books are now marked as read when you finish them in the internal reader, and the final reading position is synced when the reader closes
Fix: Metadata search works again on Calibre-Web-NextGen, and it now tells you when a source could not be searched (rate limited, blocked or missing API key)
Fix: Downloaded EPUBs open in the internal reader again instead of failing with "META-INF/container.xml file not found"
Feat: Download more than one format of a book (e.g. EPUB and M4B); the format picker marks formats that are already on your device
