Not only can you use your Apple Watch to stream music or podcasts, but you also now have the ability to download any music or podcast episode if you have an active Spotify Premium account and an Apple Watch Series 3 or later. Certain activities like going for a run or lifting weights can be hindered by having to lug around your smartphone, but you can listen using your Apple Watch with little to no inconvenience. The convenience of being able to stream music or podcasts without having to have your phone at your side at all times is actually very nice. Spotify on smartwatches is really a great thing.
You can even use the Spotify app on various smartwatches, like the Apple Watch.
The app has a presence on all major platforms. Spotify has worked its way to becoming one of the top music streaming apps.
