Publisher Description
Bring your calibre library to your iPhone and iPad. Calibre Companion helps you browse, organize and transfer the books you already own.
CONNECT YOUR LIBRARY
Connect to calibre on your computer over Wi-Fi as a wireless device, browse a calibre Content Server, or access a calibre library stored with a supported cloud provider, including Dropbox, Google Drive and OneDrive.
MAKE YOUR COLLECTION EASY TO EXPLORE
Browse covers or a compact book list. Search as you type, sort your collection, and filter by authors, tags, series and other metadata. View book details and keep track of your reading state.
TAKE YOUR BOOKS WITH YOU
Download books to your device and open them in a compatible reader app. Calibre Companion organizes and transfers books; it is not an ebook reader and does not include books.
OPTIONAL PREMIUM SUBSCRIPTION
An active subscription removes ads and unlocks Premium. Existing books and the free library remain available without subscribing. An active subscription is required for Premium and ad-free access, including for previous purchasers.
Subscriptions renew automatically unless canceled in your Apple account. Prices, billing periods and any eligible introductory offer are shown before purchase. Manage or cancel your subscription in your Apple account settings.
Use calibre on your computer to manage your library. Wireless connections require a reachable computer with the corresponding calibre service enabled. Cloud browsing requires your own account and a calibre library stored with the provider.
Calibre Companion is an independent app and is not affiliated with the calibre desktop project.

Thank you for your patience CC users! If you have immediate feedback on this release, please send it to CCfeedback@goldtreeway.com. 2.0.1 03/13/2020 - Various UI improvements
- Subscription Model
- Swift Upgrade, the program is 2.4x faster 2.0.0 09/18/2019 This version lets you see more books on the main list of books, and fixes the shortcut for opening a book from that list by long pressing on it. v1.3.2 11/06/2017 This update fixes a bug, making it compatible with iOS 11! You can now open books easily again. v1.3.1 10/05/2017 Main bug fix is to ensure books are still marked as on-device after changing their read status. v1.3.0 07/06/2017 It's now easier to download books from the content server; you can now start multiple downloads at once, rather than having to wait for each download to complete before being able to choose another book. v1.2.0 05/02/2017 More bug fixes in the Wireless Device connection process. v1.1.1 02/12/2017 This update (v1.1.0) brings some bug fixes for when synchronising the read and date read columns with calibre. Next up are some niceties like remembering your previous settings for grouping by first letters in the grouping drawer and sorting on the main list/grid screens. It also now displays the series number for books marked as book 0 in a series.
Finally, this version has changed a lot behind the scenes as it now uses Swift 3, the latest version of Apple's programming language. Please let me know on the support forum if something no longer works as expected. v1.1.0 01/09/2017 I've just added support for Calibre's custom columns with comma separated values. CC now also cleans up the grouping/filtering drawer to remove empty options for custom columns. v1.0.5 12/13/2016 This update fixes the bug where only the latest book downloaded from the content server would be available. v1.0.4 11/30/2016 This version fixes the bug introduced in v1.0.2 that meant book covers were no longer downloaded from the Content Server. Sorry!
This version also adds the series name and number to the main list of books. v1.0.3 11/16/2016 I've fixed the issue with series numbers not appearing or being used when sorting. Also a bug fix towards helping CC manage very large libraries (10,000 or more books). v1.0.2 11/14/2016 We've fixed some typos and minor issues on the Cloud Connection system. 1.0.1 11/10/2016 1.0.0 11/07/2016
