Spotify is Coming to Apple Watch With Beta App Available Now
A few Reddit users participating in Spotify's public beta testing program have shared screenshots of the app's icon, playback controls, and recently played list with a toggle for shuffle mode.
According to one Reddit user, offline downloads are currently not supported, but the feature could be added later of course. The user also says the app has yet to be optimized for 40mm and 44mm sized Apple Watch Series 4 models, but that's also something that could be taken care of during the beta testing period.
An official Spotify for Apple Watch has been long awaited, especially after third-party app Spotty was discontinued.
Update: In a statement provided to MacRumors, a Spotify spokesperson said "we're always testing new products and experiences, but have no further news to share at this time."
