Wear Music Player

Play music on your Wear OS watch. You can play music offline, mp3 and m4a. With the app on your phone, you can upload music from your phone to your watch.
The connection between watch and phone is made via Bluetooth. To transfer your music faster, Wifi will be used (only when both devices are connected to the same network).

The app requests the foreground service media playback, this is needed to make sure the music continues to play when the app goes into background. So the music continues to play when you start an exercise with a different app.
