MP3 Audiobook Player + YouTube

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

I use this app. to hear the Bible, usually while exercising on a ski machine (with a separate Bluetooth speaker). The audio Bible I have is in German, so I get some language practice, too. The app. keeps the files in their proper order, which iTunes did not. I see the app. has a procedure built in for uploading files to the iPhone. I had already used 3rd party software to do that for a previous iPhone, and these files came over to this phone when I got a new phone. This app. clips the chapter number just a little when starting a new chapter, but only when using the Bluetooth speaker, so that may be a problem wit the speaker software. My previous audio book player did not do that. Other than that, it does what I want.

I only wish I had found this App earlier. It would have saved me hours of converting audio books. This app is really easy to use and plays audio books on my iPhone 6 in mp3 format with no problem. It's easy to transfer books via iTunes. All round fantastic app, and I purchased the pro version within a hour of using it.

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 default music player doesn’t make it easy to add audio books from mp3, you can do it but it’s a pain in the but. This app makes it easy! I have been using it for years and I have been getting the updates for free! After my 1 time purchase. I like this app so much I deleted the music app and just have this.
