A:Answer No. You can do almost everything from your watch that you can on your phone. It does, however, use a lot of battery if you did it all day. Now, just going out for a run using the app and music is not a big deal. But being able to leave your phone at home is one of the best features. It will also work with Spotify. It is a bit tougher to search and play specific music, however. Best used if you are just choosing playlists that you’ve already made.
