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!

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.

Thanks for your kind words 🙏😊 I am very happy to announce that our next release adds all the goodies you have asked for to the bookshelf! Regarding the close notification, I think that I agree actually. Let me think a bit about it 🙂 TTS speed can be changed in the options menu in the read aloud controls popup 👍 Cheers from your Colibrio friends

I love this reader, its simple interface is amazing and I love that, but I would like to find an option to import my own fonts.

A refreshing new kid on the block—this ebook reader is sleek, functional, and surprisingly versatile. The customization options already make reading a joy, but imagine the possibilities if external fonts and possibly a solar theme were supported. That little touch could turn a good reader into a great one!"
