What you can do in Keiko League

Keiko League is a training bout tracker for club sessions in sumo, judo, and BJJ. You can start a QR session with a partner or run a small group session, then confirm results together so every recorded bout updates ratings from a shared result. This keeps practice logging simple, fast, and trustworthy for coaches and athletes.

Each sport has its own live leaderboard, recent bouts feed, and athlete profile pages with rating history, record stats, and achievements. Ratings use an Elo-style system so ranking movement reflects match outcomes over time, while reliability and activity context help you interpret whether a rank is based on consistent recent participation or only a small number of bouts.

The platform also includes referral invites and Stripe credit top-ups for active clubs. Whether you are organizing weekly keiko, tracking individual progress, or building a clearer view of local training performance, Keiko League gives you a sport-specific workflow from first session check-in to confirmed result and updated rankings.
