The feed is where you can see your recent activity, as well as that of anyone you are following. There are two screens: "following" and "only me."
If you are following other people, you will see their activity combined with your own on the left screen. You can toggle to the other screen to see only your own recent activity.
Each activity in the feed will show you information about the distance, type of swim, pool size, total time and total calories. If you tap a specific activity in your feed, you can see further details about the swim. See more about the activity metrics.
Below the information about the activity, you can "like" the activity or leave a comment, as well as see how many "likes" and comments are already attached to the activity.
Clicking "view all" shows all "likes" and comments on the activity.
