Issa Reader is a native reader for Storyteller, the self-hosted server that lines an ebook up with its audiobook so you can move between reading and listening without losing your place. REQUIRES A STORYTELLER SERVER Issa Reader is a client, not a bookshop. It has no catalogue of its own and nothing to sell you. Point it at a Storyteller server you run, sign in, and read your own library. Without a server, there is nothing here to show you. READ A real typesetting engine, not a web view. Pages are laid out natively, so turning one is instant and the type is properly set. Six bundled reading faces, including Literata, Source Serif 4 and OpenDyslexic, or add a font of your own. Four page themes for daylight, lamplight and the middle of the night. Size, line spacing and justification are yours to set, per book or for everything. LISTEN Variable speed with pitch correction, chapter and sentence navigation, skip controls, a sleep timer, and full Now Playing support on the Lock Screen and in Control Centre. READ ALONG This is what Storyteller is for. Where a book has narration aligned to its text, the words light up as they are spoken, the page turns itself to follow, and tapping any line starts the narrator there. Stop reading, keep listening, and pick up on the same sentence — the two stay in step. IN THE CAR CarPlay gives you your shelves and chapters as proper lists, with Now Playing and a resume that lands on the sentence you left, not somewhere near it. Steering-wheel buttons, headphone controls and on-screen controls can each be remapped independently, so the same button can do different things in different places. YOUR WHOLE LIBRARY, ON DEVICE The catalogue is fetched once and kept locally, so searching by title, author, narrator, series or tag is instant and works with no signal at all. Shelves are built on your device from what you actually have. Download books to read and listen offline. ON EVERY SCREEN A Home Screen widget with your current book, chapter and progress. Native apps for Apple TV and the Mac are included with the same purchase, and Handoff carries your place between them. BUILT FOR THESE PLATFORMS Written in Swift for iPhone and iPad, using the system's own text engine, audio stack and accessibility support throughout. Dynamic Type, VoiceOver and reduced motion are respected, not retrofitted. Issa Reader is an independent client and is not affiliated with the Storyteller project.
