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).

Fantastic Application!

I started a book club with some family members just as a way to keep in touch with one another as we are separated in different countries and states here in the US. At first we were doing only physical books and ebooks but we started incorporating audiobooks for convenience. Since I’ve always had a Plex library the first thing that came to mind was to add the audiobooks to my library for all of us to listen too and have access.

Prologue has been a phenomenal find! It syncs perfectly with my Plex library and even allows each person to choose their Plex profile! I’ve had literally zero issues as I’ve used this application. The developer is also amazing and super quick to respond to feedback.

Cannot recommend enough!
