## What is Murmura?

You have PDFs, EPUBs, and documents you'll never find time to read. Murmura turns them into audiobooks you can listen to anywhere — with AI voices that sound human and word-by-word highlighting that keeps you in sync.

Import → Tap Play → Listen. That's it.

HOW IT WORKS

1. Import any PDF, EPUB, or text file
2. Murmura detects chapters and starts generating audio instantly
3. Listen with studio-quality neural voices — in the background, on your lock screen, or through CarPlay

No waiting for an entire book to convert. Start chapter 1 in seconds while the rest generates behind the scenes.

WHAT MAKES MURMURA DIFFERENT

### 4/5 — App that clearly still requires work but has great potential

*2026-05-29*

I would submit a support request to your team however when I attempt to do so I receive the odd surprise of being bounced to a Page that presents in what looks like French with a tattoo enter button and it says private beta coming soon. This app is still requiring work as when I attempt to import my PDF files I get database not ready please restart app and try again messages. Same if I try EPUB files. Everything on the screen so far appears to be clearly labelled but I can’t test the player screen without uploading a file. Also every time I start the app, it behaves as if I never started the app in my life when I started it multiple times. Fix these bugs and I will rate the app according to it potential not its current function. This rating is for current function. still waiting for TestFlight link in my email. I did attempt to email you but never received a response so please feel free to post the link in the review response box. Thank you.

**Developer response:** Hi Blind Harper, thank you for this! It's really useful. I know that this app still requires a lot of work and my team is doing their best to crack some of these technical challenges. But we'll get there. Some of these should be resolved now with the upcoming release. Also if you're interested, I'd like you to be invited on TestFlight with a Max subscription. Please email me at: michael@datachainconsulting.com

### 1.9.33 — 2026-06-11

What's new in 1.9.33

- FIX: App no longer crashes at launch due to a duplicate keyboard shortcut conflict on iOS 26.

- Bug fixes and stability improvements.

### 1.9.31 — 2026-06-09

What's new in 1.9.31

• SMOOTHER NARRATION — Reduced CPU usage during playback by 50%. Word tracking and auto-scroll now run at optimal frequency with zero wasted work.
• SMOOTHER AUTO-SCROLL — Text follows the narrated word with less jitter. Scroll animations are longer and only trigger when the active word drifts far enough off-center.
• LARGE BOOK NARRATION — Books without chapter headings reliably generate audio. Documents are intelligently split so narration never fails due to size limits.
• CHAPTER-BY-CHAPTER AUDIO — Each section gets its own audio file with proper word-level sync.

• Bug fixes and performance improvements.

### 1.9.30 — 2026-05-29

What's new:

• ZERO-ALLOCATION WORD TRACKING — Active word highlighting now uses in-place textStorage mutations with zero memory allocation per word change. Buttery smooth at 60fps.
• KARAOKE-STYLE HIGHLIGHT — Active word now has a subtle amber background glow + thick underline for much better visibility during narration.
• SMOOTH PER-WORD AUTO-SCROLL — Text now smoothly follows each word as it's spoken (not just per-paragraph). Feels like Kindle Whispersync.
• BACKGROUND CHAPTER CONTINUITY — Fixed issue where background playback stopped between chapters.
• TOC NAVIGATION FIX — Table of contents navigation now properly syncs audio to the selected chapter.
• Bug fixes and performance improvements.

### 1.9.16 — 2026-05-22

• REDESIGNED LIBRARY — Cleaner layout with hero section, faster search, and prominent import button.
• SETTINGS OVERHAUL — Split into Appearance, Narration, Storage, and About sub-screens.
