Voice Audiobook Player

Annoyed by all the ugly players packed with endless menus and features who distract you from what you want to do: listen to audiobooks?
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!
• Bookmarks
• Android Auto
• Sleep-timer. You don't have to stop the player in the middle of the night.

Voice is free and Open Source. That means, everyone can see what it does. It uses minimal permissions.
