You can adjust the music and trainer volume by toggling the button at the bottom of the screen during class.
Slide the button all the way to the right to hear only your trainer or slide the button all the way to the left to only hear the music.
You may also use other music apps including Spotify, Pandora, Apple Music, etc. while using the Openfit app. We recommend first adjusting the Audio Balance (as described above). Then open your chosen music app and select your personal music.
