How to download audiobooks from Youtube for free on the your iPhone & iPad.

Loved the free version so much, I upgraded to the Pro version. Love how it can play numerous formats. Easy to use, and navigate. Hope in a future update they include the ability to autoplay the next book after the previous one ended. Not all files are always a book, so in those cases this would be perfect, as some files are per chapter from some online sources.

This is the only audiobook player I've found that can speed books up (without changing the pitch) and still keep the sound quality very good. It sounds as good as Overcast (minus a couple features like skipping empty spots and voice boosting) but makes it easy to import books (Overcast forces you to upload them to their servers with a 2gb limit).

MP3 Books is the best app I tested among many others. The reading of the chapters follows naturally and without error. A lot of nice features like the auto reading or reading time informations. The main interest is the ability to listen all free audio books and file formats, regardless of any susbcription like Apple Books and others.

The app allows a lot of freedom as far as organization and playback speed. Sleep timer is adjustable and combining books into series folders is simple. Equalizer helps to adjust pitch when playing at high speeds and helps reduces feedback with poor quality recordings. App never crashes and I don’t have any complaints.
