L&N Reader
Lectures and Narrations
Free · Designed for iPad. Not verified for macOS.
Audiobooks with the text in step: the EPUB highlights each sentence as it's read to you. Sleep timer, AirPlay and Google Cast. No accounts, no tracking.
Lectures and Narrations — a player for enhanced, multi-voice .m4b audiobooks on iPhone and iPad, with an EPUB companion reader that highlights the text in sync with the narration.
PLAYER
• Chapter-relative scrubbing with a whole-book progress strip and live time remaining.
• ±10/30 s skips, previous/next chapter, tappable chapter list.
• Pitch-preserving 0.5×–3× speed, remembered across launches.
• Background playback with full lock screen and Control Center support.
• Mini-player on every screen — skips, chapter and book progress, and a Read shortcut.
• Auto-saves your position and resumes where you left off.
CAST ANYWHERE
• AirPlay and Google Cast, side by side — stream to any speaker or TV while the sleep timer, reader sync, and progress saving keep working.
READER + SYNC
• Attach the matching EPUB and a sync manifest, and the text highlights itself in sync with the audio, scrolling and turning pages as you listen.
• Manual paging pauses following; Resume jumps back to the narrated line.
• Whole-book text search with in-place highlighting.
• Light/dark mode and adjustable text size, both remembered.
LIBRARY
• Import .m4b audiobooks from the Files app — or AirDrop a book to your device and it imports itself.
• Covers with progress bars; folder-style collections you can arrange by hand.
• Finish a book in a collection and the next one is offered by its cover.
IMAGES
• Every illustration embedded in the audiobook, in a gallery with pinch zoom — and as tappable markers on the player scrubber.
SLEEP TIMER
• By time or by chapters, with volume fade-out, postpone, and shake-to-postpone.
ONE ECOSYSTEM, TWO HALVES
LN began as an AI experiment in book understanding — using language models to analyze narrative structure, character traits, and scene dynamics — and grew into an end-to-end pipeline for immersive, multi-voice audiobooks.
ln-vox, the creator: an offline, self-hosted AI pipeline that ingests raw text or EPUBs, orchestrates LLMs to cast characters and direct emotional delivery, then uses local TTS to generate a fully acted, multi-voice .m4b complete with text-to-audio sync markers.
ln-reader, the consumer: this app — built specifically to play those enhanced audiobooks.

Ratings & Reviews
- This app has not received enough ratings or reviews to display an overview.
• Import a .zip of books: each comes in with its EPUB and sync file, and a zip of several books becomes a collection.
• Share a book with AirDrop, Messages or any app — with its EPUB and sync file, so it arrives complete in L&N Reader on another device.
• The sleep timer's countdown now shows on the player's cover and in the mini-player. Tap it on the cover to change or cancel the timer.
• Illustrations too close together on the scrubber now share one badge that lists them.
