Apple encourages smack talk with Activity app update (CNET News) By CNET

So with watch OS we're introducing activity sharing, and it couldn't be simpler. All you have to do is swipe to the right of your own activity rings and there you will see your selected family and friends rings as well. Now you can sort by whatever metric is most important to you, so you can sort by step, so you can sort by workouts. You can even sort by exercise minutes here. You'll see that I've sorted by the move, ring, and I'm right, where you'd expect me to be I'm, getting my butt kicked by Stacy, but I'm, a Ni all 18 Jeff, which makes me very happy. If you want to see more details, all you do is tap on anyone on your activity list, and you'll get an up close look at their activity rings, but you can also see things like their daily step count and their workouts even from third parties.

But one of my favorite features is that you can communicate directly with the people that you're sharing activity with right in the activity app through messages and when you do, you'll get smart replies that are geared around fitness and activity. Some are supportive, some are a little more competitive, but you can also do some fun things. For example, at the end of a workout, you could send your racing heart rate to one of your activity, friends or your racing heart rate to one of your activity, friends, or you can also send smack-talk in your own voice right through audio messages. So we think this is going to be a great way for you and your friends to stay motivated to keep each other active, and we can't wait for you to try it.
