Librera Reader

Book and PDF reader
Librera Reader is a highly customizable and feature-rich application
for reading e-books in PDF, EPUB, MOBI, DjVu, FB2, TXT, RTF, AZW, AZW3, HTML, CBZ, CBR, DOC, DOCX, etc. formats

With its intuitive, yet powerful, interface, Librera makes ebook reading a veritable pleasure.
It even features a unique auto-scrolling, hands-free Musician's mode, with contollable speed

For better security, the F-Droid version, is based on the latest MuPDF 1.16.1 and does not require access to the Internet.

For the above reason, some Internet-related features of Librera Reader are missing in its F-Droid version:
1) Access to OPDS (Calibre) Catalogs
2) Google Drive Syncing
3) Access to Clouds (Dropbox, Google Drive, OneDrive)
4) Saving (sharing) pages from web browsers
5) Rendering MathML formulas in epub3 books
6) Access to the What's New page

# Just a few Librera's main features:

* Easy document discovery by configurable criteria:
* Auto-Scan (user-specified folders)
* Browse folders (using an in-app file explorer)
* Recent (featuring a reading-progress indicator)
* Support for bookmarks, annotations, and EPUB3 tables of contents
* Configurable Day and Night modes
* Configurable link color (hence, footnotes and endnotes color)
* Support for many popular offline dictionaries
* Vertical-scroll lock
* Auto- and manual centering of documents
* Custom ad-hoc CSS coding
* Single-page view of two-page documents
* Musician's mode with configurable scroll speed
* Customizable TTS reading and built-in media player
* Page-wise TTS recording to MP3 or WAV
* Multi-word text search
* Support for archived (.zip) documents

The best way to fully appreciate Librera Reader, however, is to use our restriction-free Librera PRO version from Google Play.
