A fill-percentage ring on your Apple Watch shows how many of your session’s participants have checked in, without requiring you to pull out your phone or step away from what you’re doing.
It’s built as a native watch app, not a shrunk-down version of the phone screen — glanceable, wrist-based, meant for the moment mid-session when checking a phone would mean stopping what you’re teaching to do it.
Check-in marks made from the watch — yours or a participant’s, if they’re wearing one too — sync to the same roster in real time, so the number on your wrist and the list on your phone always agree.
For a leader actively running a session with their hands occupied, this is the difference between a two-second glance and a full interruption.
