If you’ve got friends and colleagues who are also Apple Watch users, you can help motivate each other by sharing your Activity rings with up to 25 of your friends. Once you’ve invited a friend and they’ve accepted your invitation, you can see their Activity data either by swiping to left from your rings in the watchOS Activity app, or by going to the Sharing tab in the Activity app on your iPhone.
By default, this list sorts you and your friends alphabetically by name, showing your progress toward each of your move goals. You can actually change this sort order, however, to rank yourself among your friends by how far you’ve each progressed toward your daily Move, Exercise, or Steps goals, or how many workouts you’ve completed — giving yourself even more motivation to get to the top of the leaderboard each day.
In the iPhone Activity app, this is done from the Sort button in the top-right corner, while on the Apple Watch Activity app you can force touch (press hard) while viewing your friend list to access the option sorting options. On the Apple Watch, you’ll also see the current sort order displayed at the top of the list.
