User reviews

Great app for audiobook enthusiasts.

Such a great app and well worth a look if you are a fan of audiobooks.

Immersive Reading!!!!

Oh. My. God. I can listen to my audiobooks while it highlights the text as I read along with my EPUB? I thought this would be a proprietary gate-kept feature under the Amazon umbrella forever!!!

This is AMAZING. Thank you for implementing this amazing feature.

My hopes for its further development - the ability to hide the UI buttons when fully full-screen, the ability to import custom fonts, and horizontal viewing.

Thank you so much again.

Top Notch Player

This is absolutely the best audiobook player I have ever used. And no subscription is awesome. Best $10 I’ve ever spent.

Kindle Whisper Sync Replacment

Do you know of another app that lets you read along while listening highlighting each word as you listen!?

Finally, we no longer have to give Amazon our money because of this developer.

We are truly living in the future 🤯

Never going back to Apple Books

When we say “Sherlocked,” it’s a reference to Apple taking a feature of an app, usually paid, and asking it to iOS, effectively killing that app’s future business. However, iOS has stagnated in recent years and we’re starting to see it go the other way. As Apple removes features, it opens the door for third-party apps to give users what they want.

That’s what happened here. While Apple has removed features from Books, Prologue has added the ability to read along with an audiobook. It can even transcribe an audiobook to give you something to read along with, and it works quite well, but it can also import the ebook and follow along with that as well.

No more switching between Prologue and Apple Books and struggling to keep the ebook up with the audiobook. Now Prologue does both, and it keeps up on its own.

I would only suggest the option to scan line by line rather than word by word, and to keep it centred on the screen. Also to be able to import audiobooks from the Files app, not just a media server, for maximum versatility.
