What it does
Why schools trust it
Guest access works from a phone, with nothing to install and nothing to remember.
A substitute can leave notes on specific students that surface as a banner the teacher sees on return.
Every attendance change is logged with who, what, and when. Never silently overwritten.
One session can cover multiple teachers with their own time windows, for a substitute juggling a split day.
