Pulsar Player is a free iPhone app developed by Fred Anthony that allows you to easily navigate and begin playback of tracks from your Spotify Playlists, saved Tracks, Albums, and Recently Played, all from your Apple Watch. With Pulsar, you no longer have to listen to the same Playlist repeatedly or take out your phone during a workout to choose another Playlist.

With Pulsar, you can view and paginate through all of your Playlists, Albums, Tracks, and Recently Played directly from your Watch. The app offers continuous play, automatically playing the next set of Tracks from your selected list until it reaches the end. You can control the playback, including play, pause, skip forward or backward, and adjust the volume, directly from your Watch or iPhone.

It's important to note that Pulsar does not play music on your watch itself. You still need to connect your headphones or Bluetooth devices to your phone, as the music will be emitted from your phone. Pulsar simply allows you to navigate, select, and choose to play tracks from your watch without the need to do so from your phone.

Please be aware that Spotify Premium is required to use this application. Additionally, Pulsar uses content provided by Spotify but is not sponsored, endorsed, certified, or otherwise approved by Spotify. Please note that Spotify does not currently provide an SDK for watchOS, which means that playback directly from the Apple Watch is not possible at this time.

Overall, Pulsar Player is a convenient and easy-to-use app for Spotify users who want to control their music playback from their Apple Watch. With its intuitive interface and seamless integration with Spotify, Pulsar offers a hassle-free way to navigate and play your favorite tracks without having to reach for your phone.
