The five stations - registration desk, tagging, beach master, tallying and safety lead - and how they fit together.
On the day, WeMuster answers one question: who is still on the water? Tallying is the count of who has gone out and who is back. Everybody taps a band as they launch and again as they land, and the safety lead watches the number still out until it reaches zero.
Each one is a station: a phone, tablet or laptop opened straight into that one job by a link or a QR code, with no sign-in. A small event can have one person holding two, or use only the ones it needs. See Setting up stations.
Every station has a ? button in its top corner that explains it in plain words. A volunteer handed a phone can work out what to do without asking.
WeMuster is an aid to the roll call, not a safety system. It tells you who to go and look for; it never tells you somebody is safe. Keep your usual safety cover, and a paper backup of the count.
