Connect your Calibre library via any cloud provider and read your entire collection on iOS. Full folder structure, metadata, covers, and series organization preserved perfectly. The Calibre companion app that power readers have been waiting for.
Open justRead, tap Add Library, and select your Calibre library folder from iCloud Drive, Dropbox, Google Drive, or OneDrive. justRead detects Calibre's folder structure automatically.
justRead imports your entire Calibre collection with metadata, covers, series info, and folder organization intact. 5,000+ books? No problem.
Pick up any book and start reading with full customization: 200+ fonts, adjustable margins, themes, and smart dark mode.
justRead preserves everything Calibre users care about: your folder hierarchy, author metadata, series grouping, custom tags, and high-resolution covers. Navigate your library exactly the way you organized it in Calibre.
Unlike generic ebook readers that flatten your library into a single list, justRead maintains your Calibre folder structure. Browse by author, series, genre, or any custom folder organization you've built in Calibre over the years.
Series order, author names, book descriptions, custom columns, and cover art all transfer automatically from your Calibre library. No manual re-tagging or re-organizing on your phone.
Sort by any Calibre metadata field: title, author, series index, date added, or reading progress. Filter by tags, series, or reading status. Your Calibre organization becomes your mobile organization.
Whether your Calibre library has 50 books or 50,000, justRead handles it without slowdowns. Tested with massive collections that make other iOS readers crash or freeze.
Stream books directly from your cloud storage without downloading everything to your phone. Your 500GB Calibre library doesn't need 500GB of phone storage. Open any book instantly from the cloud.
Store your Calibre library on iCloud Drive, Dropbox, Google Drive, or OneDrive. justRead connects to all four. Move between cloud providers anytime without losing your reading progress or library setup.
Already using Calibre Content Server or OPDS? justRead supports OPDS feeds too. Connect to calibre-web, Calibre's built-in server, or any OPDS-compatible source alongside your cloud-synced library.
