To add a friend you share an invite link; for a challenge you send one of your results with a “beat me” link and your friend responds by measuring in the same sport. Both results are then shown side by side.
Friends
Create an invite link from your profile/menu and send it to a friend. When they open it you become friends and see each other on the “Friends” leaderboard tab. Reach 5 friends to earn the 🤝 Team Player badge.
Challenges
On a result screen the “Beat me” button produces a link. Your friend opens it, measures in the same sport and responds. A winner 🏆 is decided; the winner gets the ⚔️ Duelist badge. Unanswered challenges expire after 7 days.
Teams
Create a team (name, emoji, optional sport), invite members with a link, and compete on the team’s own leaderboard. You can keep a team private; child accounts only appear in private teams. For the coach role, see Setting up a team for coaches.
