Run your own league — for any sport

Veterans, over-35s, 7-a-side, a padel ladder or a regional friendly league. Muster handles the schedule, the results and the standings. All via WhatsApp, no separate app.

For all sports

Football, hockey, tennis, padel, volleyball, korfball and more — with the right scoring per sport.

Results via WhatsApp

The home coach reports the result, the opponent confirms. Is there a referee? Then their result is final straight away.

Live standings & schedule

A public page with standings, schedule and results. Share it with a QR code or have players message LEAGUE to Andy.

Fair Play

Afterwards, coaches rate the opponent’s sportsmanship — mutually, so no revenge scores. Optionally counts towards the standings.

Referees

Assign a referee; they get the match details and a reminder via WhatsApp, and can cancel if they can't make it.

Guest clubs free

Only the organising club pays. Participating clubs and guest teams join for free — even without Muster.
