Offline-first reading for phones and tablets
Fablum - Private E-book Reader for EPUB and PDF
Fablum is a private ebook reader built for people who want their library to stay local, readable, and under their control. You can open EPUB and PDF files, browse free books from OPDS catalogs like Project Gutenberg, and listen with built-in text to speech without handing your reading life to an account system.
Most readers force a trade. You get a decent interface but weak format support. You get lots of features but half of them need a subscription to unlock. You get cloud sync and storefronts, then discover the app is really built to sell you something. Fablum takes the opposite route. It starts with reading itself: a clean library, a focused reader, dependable progress saving, and the kind of small details that matter after the twentieth book, not just the first launch.
It is also an offline ebook reader in the plainest possible sense. Your books stay on your device. Your progress stays on your device. Search, sorting, themes, and text to speech still work when the network disappears. The online pieces are the ones that should be online: pulling in a new book from a URL, browsing an OPDS catalog, or checking what is available to download.
