Import your own EPUBs, download public-domain classics from Project Gutenberg and Standard Ebooks, and keep everything organized in a library that feels made for reading. Covers, progress, metadata and collections all in one place, without ads or a social layer around your books. READ COMFORTABLY Choose from carefully tuned themes including Paper, Sepia, Night, and OLED Black. Adjust fonts and text size, then let Flumen remember your reading preferences for each book. The reader keeps the interface out of the way so the page can take the room it deserves. DISCOVER CLASSICS Search and browse public-domain books from trusted sources, preview book details, and download directly to your library. Explore authors, genres, popular classics, and curated rows without leaving the app. ORGANIZE YOUR LIBRARY Sort by recent, title, author, or progress.

READING PROGRESS THAT FEELS USEFUL Flumen tracks where you are, how much is left, and your active reading time. Optional goals, streaks, monthly summaries, and reading statistics help you understand your habits without turning reading into homework.
