Colibrio Reader for EPUB & PDF

Colibrio Software AB

About this app

The Colibrio Reader is an implementation of the Colibrio Reader Framework, the most advanced development framework for building digital reading systems.

Colibrio Reader supports all of the features in EPUB3, including,

* Talking Books (Media Overlays)
* Interactivity (Scripting)
* Reflowable and Fixed Layout
* Text to Speech
* Bookmarks
* Annotations

and much more!

We have chosen to make this app free to all to help people that are looking for an accessible e-reader and to help promote EPUB as a format.

This app will be updated regularly with all our latest features at the time they reach their Beta stage. So you can look forward to a steady stream of fun new features!

A note to screen reader users, the app works best when used with the Google TalkBack service. Also, for accessibility testers, please turn on TalkBack before you start the app.

Now go read a good book!

We are looking forward to your feedback!

Ratings and reviews

Great app for listening to your audiobook while your book pdf is synchronised but there are some features that I wish existed. You can't fully customise the theme other than using the presets already present. I wanted the background to be black and the text to be gray but that's simply not possible. Also, there's no offline dictionary. This means not only you need the internet to know the word meaning but you also need to wait for Google to open and load every time you don't know a word.

Great app for reading EPUBs, uses CSS file to format books correctly and has loads of options to customize the look and feel of the books. It would be great to have extra options in the book-list section, to be able to sort them by filename, author and last read. The TTS option is good but reads a little slowly (I was using my phone); great for testing epubs to see what works and what doesn't when designing them for accessability. Having to confirm closing a book each time is annoying, though.

It's beautiful like Moon Reader but free and without ads like Lithium! 👍🏼 It can display math formulas correctly. I haven't tried chemical formulas, but I hope it's covered. Definitely better than Lithium. I hope you will add feature to lock orientation to portrait.
