How to Read Calibre Ebooks on iPhone & iPad — CaliMob Guide
CaliMob is your Calibre library on iPhone and iPad. Here's how to get started in 5 minutes.
Have a Calibre library and an iPhone? For years the options were thin — the best-known Calibre companion app was Android only. CaliMob brings your whole Calibre library to iOS: a full reader for EPUB, PDF, comics and audiobooks, with sync from 7 cloud backends.
Download CaliMob from the App Store
Get CaliMob from the App Store on your iPhone or iPad. It's free, with no ads and no account required. (There's an Android version too, if you switch devices.)
Try the Demo Library
Don't have books on hand? No problem. CaliMob can connect to a Demo Library with free public domain ebooks, comics, and audiobooks so you can explore every feature right away. You can also browse the demo online.
Open CaliMob → Add Library → OPDS → enter the demo URL. The demo includes books from Project Gutenberg, comics from Pepper&Carrot, and sample audiobooks — all free to read.
Connect your Calibre library
CaliMob gives you 7 ways to reach your books. Pick the one that fits your setup:
| Method | Best for | Setup |
|---|---|---|
| Google Drive | Calibre library on Drive | Sign in → select your Calibre folder |
| Dropbox | Calibre library on Dropbox | Sign in → select your Calibre folder |
| WebDAV / Nextcloud | Self-hosted, privacy-first | Enter server URL + credentials |
| FTP / SFTP | Network storage, NAS | Enter server, port, credentials |
| OPDS Catalogs | Online libraries, demo library | Enter catalog URL |
| Calibre Content Server | Direct connection to Calibre desktop | Start server in Calibre → enter local IP |
| Files app & iCloud Drive | Books already on your iPhone/iPad | Browse via the iOS Files app and import |
On iOS, local books are imported through the system Files app, so anything in iCloud Drive or "On My iPhone" is one tap away.
