Local Narrator vs OSHello

Your books, read aloud — privately, on your iPhone. Local Narrator turns any EPUB or text-based PDF in your library into a real audiobook, narrated by a warm neural voice that runs entirely on the Apple Neural Engine. Nothing leaves your device. There is no cloud. There is no account. There is nothing to opt out of. — BRING YOUR OWN BOOKS — Drop in EPUB or PDF files from the Files app, the share sheet, or AirDrop. Your books stay on your iPhone, and the audio they become stays there too. No upload, no forced sync, no backup you didn't ask for. — A REAL NEURAL NARRATOR — Local Narrator runs Kokoro-82M, a state-of-the-art on-device text-to-speech model, on the Apple Neural Engine. The voices are warm, natural, and quietly expressive. When you'd rather not download the model, Apple's built-in system voices work for free. — BILINGUAL, AND SMART ABOUT IT — English and Spanish. Local Narrator detects each book's language and picks a voice trained for it. Spanish voices are still in beta stage. — LIKE AN AUDIOBOOK SHOULD BE — • Background playback that doesn't stop when the screen sleeps • Lock-screen controls — play, pause, +30, −15, scrub • Home and Lock-screen widget with a clean amber progress ring • Sleep timer for reading yourself to sleep • Per-book reading position, automatically saved • Unlimited bookmarks • Adjustable speed from 0.5× to 3.0× • Light parchment or dark charcoal reading themes • Full Dynamic Type and VoiceOver support — PRIVATE BY DESIGN — No accounts. No telemetry. No advertising SDKs. No third-party trackers. The only network call the app ever makes is the optional, one-time download of the Kokoro voice model. After that, everything works in airplane mode. — ONE PURCHASE. YOURS FOREVER. — Free to download and try with one book and Apple's system voices. A single $4.99 in-app purchase ("Local Narrator Full Access") unlocks unlimited books, all neural voices, the full speed range, the widget, the sleep timer, and unlimited bookmarks. No subscription. Family Sharing supported. — BUILT FOR REAL iPhones — iOS 17 and newer. iPhone 15 or later (Pro version recommended), optimised for the Apple Neural Engine. A small, careful app for people who still read.
