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).

Great augmentation for Plex. Best in class design. Needs Bookmarks.

Beautiful design. Does what it says. Does it well. Great augmentation for Plex.

For context: I am moving over from the Bound App (and several other prior). I listen to a dozen or two audiobooks each year on top of hundreds of hours of podcasts in Overcast.

The only glaring absence this app is bookmarks: if I fall asleep listening to an audiobook, bookmarks are a huge help in finding the point I last recall.

If it could pull sleep data from Apple Health to automatically mark where I likely fell asleep I’d find some way to give this app six stars.

Voice Boost EQ feature produces some audio clipping on well-mastered books, but is helpful for lesser sources. I understand good voice boost algorithms are a major undertaking in audio processing, so I’m still glad a simple EQ fix is offered.

It’d be great if time skipping buttons were smart enough to increase the skipping interval with repeated taps to allow faster search (like Overcast). Still, I’m aware of no other audiobook app with this feature, so it’s not a relative shortcoming.

Five stars for Prologue, because grade inflation is real, and this app deserves notice. Insta-buy for me, and I plan to throw in a tip with each book I finish.

Great for large libraries

Works wonderfully for audiobook libraries. Apple seems to have abandoned this space and confines its Books app to a computer’s boot drive. This means you have to keep your library small. Prologue solves this issue. Would pay a subscription or large fee if it could stream audio and audiobooks to my Apple Watch. Side loading would work, too. Audible kind of side loads, but it’s not reliable. Audible does not stream or offer direct downloads. Apple will stream and offer direct downloads, but what about the hundreds of books I have outside the closed universes of Apple and Audible?
