Meet Andy
Andy is Muster's digital assistant. He keeps track of what's going on in the team: which trainings and matches are coming up, who's available, and what needs arranging.
He never posts anything in your group himself. He writes the message, gives the coach a nudge, and the coach sends it — from their own WhatsApp, in their own group. So the group stays the team’s, and the coach sees every message before it goes out.
How it works
From first message to a fixed routine, in three steps.
The coach adds the Muster number
To the existing team group — same group, same members, same history. No new group to create, no players to re-invite.
The team sends short commands
PRESENT, ABSENT or MAYBE LATER — players reply just as they already chat. The system tracks the status.
You pick the line-up, with a clear overview
Based on the replies you see at a glance who's coming — the line-up stays your call as coach.
