What it does
Prologue plays audiobooks from Plex and Audiobookshelf. It is free to download, with additional features available through a one-time unlock.
Set up a compatible media library before choosing Prologue: this is a client for your collection, not an audiobook subscription catalogue. Check the current device requirements before installing. Its official page also describes ebooks from Audiobookshelf or personal imports, widening the workflow beyond audio.
Read Along transcribes on the device and can follow an EPUB or PDF from Audiobookshelf or a personal import. The page lists iOS 26.5 or Android 13 as minimums, so device eligibility deserves checking before planning a server-based setup.
