The Short Version
WHOOP may add a direct friends feature, removing the requirement to create a full group just to follow one person's stats.
Right now, following a single friend on WHOOP means creating an entire group, which is the kind of friction that makes people just not bother. A direct friends feature would let two people compare sleep and recovery scores without any group setup. No specific launch date has been confirmed, but if WHOOP ships this, it removes the one social barrier that makes the app feel more like a corporate wellness tool than something you actually use with friends.
