Amazing

A great app for audiobooks, easy to find and add books and connects to multiple sources. Keep up the great work!

Made up fake metadata

Update: thanks for the info about the Metadata setting, but it doesn’t really do anything useful. I shouldn’t have to go through and edit made-up metadata. It would be better if you included a setting to prevent the app from trying to guess what my files are. Outside of the app, all of my files either already have real metadata or are organized in to folders. The app’s unwanted attempts to automatically find something I’m not looking for l make it useless.

Original:
This app looked to be exactly what I wanted: and audiobook player that supported syncing with a local folder. However, when I add the folder, it made up fake, useless metadata for a great number of the files in the folder. I’ve deleted the app for now.

Response from developer

Thanks for trying and I appreciate your feedback! The behavior you experienced can happen if some of the audiobooks were a collection of m4a, m4b files. There is a 'Manage Metadata' option in Settings to handle this. Or you may manually merge multiple files into a single book under 'Update Metadata'.

Thank you for the App

It works like a charm.
