EPUB reader in sync with your own calibre-web, Komga or OPDS book server.
Liseur is a free, open-source ebook reader for Android. It reads EPUB books from a folder on your phone, and it connects to your own calibre-web, Komga or liseur-sync server so your whole library lives on one shelf. No ads, no trackers, no analytics, no Liseur account. Network access is limited to the book servers and dictionary sources you choose, plus Project Gutenberg when you add free books.
YOUR LIBRARY, ONE SHELF
* Folders on your phone or SD card, indexed with covers * calibre-web, Komga, liseur-sync and OPDS catalogs merged into the same shelf, with a cloud badge on server books * Series grouped in reading order, with progress and missing volumes at a glance * Free books from Project Gutenberg to start you off, before you connect anything
READ YOUR WAY
* Pages or continuous scrolling, per book or library-wide * Bundled open typefaces (Literata, Vollkorn, Atkinson Hyperlegible, Inter) or the publisher's own * Margins, line spacing, brightness and four reading themes: light, sepia, dark, and black for OLED screens * Auto-scroll at your pace, carrying on across chapters * A footer with the current page, what is left in the chapter, and time remaining * A refresh mode tuned for Onyx e-ink displays
YOUR PLACE FOLLOWS YOU
* Your reading position syncs across devices through calibre-web, Komga or liseur-sync, down to the exact sentence * Pair any OPDS catalog with any kosync server as a single Custom connection * Settings sync and reading statistics across devices when you connect liseur-sync * Close the book on your phone and pick it up on your tablet
HIGHLIGHTS, NOTES, DICTIONARY
* Highlights in four colours, notes and bookmarks, gathered in a per-book notebook you can export as Markdown * Search the whole book and jump straight to the passage * Footnotes open as a card over the page instead of sending you to the back * Definitions from Wiktionary or an offline dictionary app; online lookups stay off until you turn them on, and you pick the source
FREE SOFTWARE, BY DESIGN
Liseur is built on the open Readium toolkit, with no proprietary dependencies and no Google Play services. Source code, issue tracker and documentation: https://github.com/chmouel/liseur
Browse extra catalogs like calibre-web, Komga, OPDS, and Project Gutenberg to download specific books or categories without syncing them to your main account. A new floating bar controls automatic scrolling, letting you pause, adjust speed, and save your exact spot when stopping. You can also add a home-screen widget to browse your library covers, while reading-time widgets provide more accurate multi-device totals.
