Running is much more fun with music. Zombies, Run! has a couple of different options for including music in your run. Choose your music settings by tapping the music button on any mission screen.
To use the ZR Player, create a playlist using a compatible player like Android Music Player or Shuttle Music Player, and select the playlist in the Zombies, Run! app. You will need to have all of the music stored on your device to use this option.
Streaming / External Music
To use an external or streaming music player such as Google Play Music or Spotify, select the External Player option on the music settings screen. Start playing your music in the external app before starting your mission, and ZR will pause or lower the volume of the music in order to play mission clips and announcements.
