Reader Feeder is an OPDS catalog client and download manager. What's OPDS? It's an XML format based on Atom that document providers use as their catalog format. Who uses it? The Internet Archive and Project Gutenberg to name two free sources of countless 1000s of free e-books!
Reader Feeder has special support for the Librivox EPUB audio books on The Internet Archive, and will extract the audio (and other content) file info, help you download these files, and automatically add them to device's media scanner. Better yet, use the built-in audio player that gives you direct access to the Chapter markers for ultimate control.
Reader Feeder also downloads any content types offered, so that also means Text, HTML, PDF, Kindle in addition to EPUB, so you can keep all your readers and media players happy! All downloads are saved to External Storage for easy shared access (permission must be granted for latest Android versions).
Reader Feeder also integrates with Voice Search, so you can trigger it from the Google App (after enabling it in Settings).
