Who is in, and what they are drilling
A board that shows, live, who is on the mat, grouped by belt — and beside it what that belt is learning today.

The app in use, recorded.
The Active attendees page is not a list but a board: every session running right now is a section, inside it the people present by belt, and next to each belt what the training plan has set for it today. What happens at the door shows up here seconds later.
One tap on a member
Tap someone on the board and you get what they have actually trained over a period of your choosing — counted across every group they belong to, because the question is about the person. If one of the bars is too short, tap it and that exercise goes straight into today’s session, for the member’s belt or for everyone.
Why attendance is the truth
The board reads the arrivals, not the timetable. A group is active when somebody has actually signed in — if a session is cancelled, the board stays empty and shows nothing that is not there.
