Calibre Access
Read full descriptionHide full description
Access your Calibre library on your iPhone or iPad. Calibre Companion connects to your Calibre library folder and displays your books, their authors, and the available formats. Features: • Browse your Calibre library • Quickly search for a book by title or author • Open your books directly from the app • Supports multiple formats for the same book • Refresh your library at any time to see your latest changes Calibre Companion works in read-only mode: your Calibre library and its metadata are never modified by the app. After making changes to your library on your computer, close Calibre so that all changes are properly saved and can be synchronized with Calibre Companion. Calibre Companion does not bypass DRM: opening a protected book depends on the app used to read it and its support for the relevant format and DRM.

The clearest difference is in-app purchases: Calibre Access at none against Sutra's 4. On price, ads, device support and iOS requirement there is nothing between them.
