I use the Nike app to track my walks. I use it to control Sonos music on the patio, control home lighting, use it to confirm VPN connections to work, listen to podcasts when I walk over the watch's cellular connection, take phone calls when my phone isn't with me, get notifications from my work calendar, get reminder notifications, see where my Uber driver is, get verbal feedback for directions when traveling, use the alarm function when traveling, get reminders, blah, blah, blah
