You just add your main audiobook folder and every folder in there will be recognised as a single book. That keeps your library simple and tidy. Here we go.
What it can:
• Remembers last position
• Adjust playback speed
• Beautiful Material Design
• Day & Night Theme. Don't hurt your eyes!
• Android Auto
• Sleep-timer. You don't have to stop the player in the middle of the night.
