What’s New

In 3.5.6:

- Fixed issue causing books to fail to sync to watch app

- [Watch] Support for finer-grained playback speed. Tap the label (e.g. “1x”) to show presets
- [Watch] Fixed an issue where chapter skip controls could show “x of 0” chapters
- [Watch] Fixed an issue causing book title to be displayed twice on placeholder covers (i.e. when cover images haven’t yet loaded)
- [Watch] Potential fix for additional “Other” storage usage after downloading a book

In 3.5.3:
- [Watch] Complications should update more reliably when playback progress changes on the iPhone app
- [Watch] Fixed a crash when downloading large files (2.1gb+)
- Don’t show watch app purchase button on Settings tab when a paired Apple Watch is unsupported

In 3.5.2:
- [Watch] Added chapter skip controls (under the “...” menu on the now playing view)
- [Watch] Fixed an issue causing the initial watch app data load to fail
- [Watch] Fixed a couple of crashes

In 3.5.1:
- Fixed a crash when starting playback from CarPlay when “Show automatically” player setting is enabled

In 3.5.0

Prologue is now available for Apple Watch!
• Stream books you're currently reading, or books in your reading list
• Download books to listen when you're offline
• Widget and complications

Prologue for Apple Watch is the culmination of months of work by a single developer.
To keep Prologue financially sustainable, I’ve decided to ask for a small extra payment to use the app.

Thank you for the continued support!

Not only does it sync effortlessly with Plex and immediately across my devices, but it was built by someone who loves audiobooks. It was the easiest money I've spent on an app since Anki.

The app is sleek and packed with helpful features on both the iPhone and Mac Mini. The metadata from Plex (Audnexus agent) syncs over and looks amazing on here. There's many playback speed choices, a sleep timer, and a voice boost that works well. But the feature I love most is the bookmarking ability for notes. Previously with the "Books" app, I would have to screenshot where I was at in the audiobook for every note that I wanted to take (later when finished with the book). I would even add text to the screenshot sometimes in Markup, to make sure I filed the note correctly. But not anymore. Every audiobook "Summary Page" has three tabs below all of the book info: Chapters, Bookmarks, and History. And in the Bookmarks tab, all your bookmarks, along with any optional notes that you can type with them, are filed neatly, and the audiobook jumps to each bookmark when tapped. It's incredible and such a time saver from what I was doing. Incredible app. I'm sure I'll find more good things about after this first day of use.

A must have for anyone listening to books on Plex

This app is better than audible or the plex app by far. The embedded chapters and bookmark features work really well. I’m disappointed with Audible on how very few books have titled chapters. With this app, however, I can take actually title my own books. Before finding this app, I always had doubts on whether my friends and family could easily use Plex for audiobooks. You had to know where to click on an audiobook to actually resume it. And for audiobooks with multiple files? Forget ever trying to resume your spot In an audiobook if you even thought about playing other media. I could live with all of those shortcomings, but I’ve always had the thought in the back of my mind that some of my family and friends would do better sticking with Audible. All those pain points are no longer a thing, and I can recommend using audiobooks with Plex now, thanks to this app.

Also, the developer has been super responsive. I can tell that continuous improvement is important to him, and this gives me confidence in this app. Can’t say the same about Plex’s support for audiobooks (don’t get me wrong, I love Plex for movies and tv shows).

Would be 5 stars except for ONE thing

I love this app and use it literally every day. Paid for premium because it's worth every cent and more. My audiobook collection is.. large.. and so I'm usually searching instead of just browsing. My issue is that search is limited to 15 results. For example, I have 36 books by Bernard Cornwell in my library. Searching Bernard Cornwell only displays 15 (as far as I can tell, randomly, as books within series are scattered). Same thing searching for books read by my favorite narrators- 15 results max even on narrators I know I've got 20-30 books by in my library. Is it even possible to make it so searching gives you all results from your library or am I asking for something that can't be done for some reason?

Developer Response ,

An option to show all search results is coming in the next update (v3.2)
