Hi @Lotheric, the app has a basic support for submitting listens but it has been tested only lightly. You can enable it from the settings inside the app.
In theory, it should work with all applications but different music players handle it differently so you can test if it works with the player of your choice correctly. If it doesn’t, you can report it and I’ll take a look into it.
The complete details of this deserve a post of its own. I’ll open a ticket and write up a community post as soon as possible to explain the scrobbling features of the app.
