Favorite or most useful Apple Watch apps?

[InsertNameHere]

After trying and enjoying a fitbit charge 3, I've ordered an Apple Watch series 3 with the hopes that it will do all the fitness tracking, but also add some productivity to my life as well. Have 30 days to see if it beats out the fitbit on my wrist. So to get a head start, looking from others who have Apple Watches - what is your favorite or most useful app(s)? These can be music related, like a metronome that uses buzzing on the wrist for tempo (hopefully something like that exists!) or non music, like a great fitness or productivity app. Or as an apple watch user, do you find it useful at all?! Would love to hear your thoughts.
