Works exactly like it should

Finally found an audiobook player with cloud API support to my private library.

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.
