Most readers force you into one format. Fanfic Reader is a native iOS/iPadOS library that opens EPUB, FB2, PDF, MOBI, DJVU, CHM, comics, Office docs, Sketch/Figma, and archives — without converting.
What stands out: built-in AO3 Discovery (search, queue, EPUB import), full-text search, TTS with background playback, Wi‑Fi Transfer, iCloud sync, Share Extension, and a Continue Reading widget. Privacy-first: no ads, no accounts.
