Take the register

One page for marking who turned up, and for seeing how the last four months have gone.

Steps

Open Attendance from the Club group.
Use the Today and This week registers at the top. Each enrolled player is one row.
Tap a player's row to mark them Present. Tap again for Marked absent. Untouched, they read Not marked.
Scroll to Last 120 days for the enrolled, checked-in and present counts per session.
Press Download CSV for the row-level figures.

Only Group sessions appear. One to ones are deliberately left out of the register.
A row marked Self with a time is a player who checked themselves in from their portal. Your mark always wins.
Marking a player present stamps an arrival time if there is not one already. Marking them absent leaves the time alone, because they may well have turned up and left again.
Every tick is written to the audit trail, because attendance drives charging.
The CSV covers the last 120 days, up to 500 sessions, with a row per player per session.
