What it does
Why schools trust it
Autosave and a live status indicator, so no layout ever needs to be manually exported or re-sent.
The random student picker won't repeat a name until everyone present has had a turn.
A cold-covering substitute gets the identical chart a teacher would use, with attendance built in.
Marking a seat absent updates dismissal status automatically. No separate attendance step.
