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.

1

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.
