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.
ZR Player
To use the ZR Player, create a playlist in your phone's Music app, and select it in the ZR music settings. Only playlists where all music is downloaded (not being streamed through Apple Music), and does not have Digital Rights Management (DRM) will be available.
Apple Music
To play music using an Apple Music subscription, select the Apple Music option on the music settings screen. We'll reduce its volume during mission clips.
Streaming / External Music
To use an external or streaming music player such as Spotify or Pandora, 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 lower the audio of the music in order to play mission clips and announcements.
