About

Folire

Your books should feel at home on your phone. Folire brings the ebooks, PDFs, comics, and audiobooks you already own into one tidy library on iPhone and iPad. Add a file from Files, iCloud Drive, AirDrop, or the share sheet. Folire opens DRM-free EPUB, PDF, TXT, FB2, MOBI, AZW3, CBZ, and CBR books, plus MP3, M4A, and M4B audiobooks. Once imported, they're available offline. Settle in with a page that fits you. Adjust the type, spacing, margins, and colors, and choose page turns or continuous scrolling. Highlight a line, write a note, bookmark a passage, and pick up where you left off. Audiobooks remember your place too. Any book can be read aloud with the built-in system voices. On a compatible iPad, mark up PDFs with Apple Pencil. The free library holds up to five of your own books. Folire Pro is a one-time purchase for a larger library and the tools that help you go further: natural on-device neural narration for every book, auto-scroll, custom fonts and reading presets, full-library search, questions and recaps that stop at your current page, annotation export, detailed reading history, direct downloads, connections to your own OPDS, Calibre, or WebDAV library, and optional iCloud sync. Reading Assistant uses only text you've already read and processes it on your device. No account, ads, tracking, or developer-operated server. Your library stays on your device unless you choose to sync it to your private iCloud storage or connect to a server you supply. Export a complete backup whenever you need one. Folire includes four public-domain classics to start reading, but no book catalog. It can't open DRM-protected files. Optional tips support development but don't change what the app unlocks.
