Check-in
One iPad you set up once and never touch again.
The screen works it out
It always shows the class people are arriving for. There is no input anyone can forget to give it.
A code that changes
The code on screen keeps rolling over, so yesterday's photo of it lets nobody in.
Or from their phone
She scans, or checks herself in from the app inside the window you set.
Who actually came
The register fills in as people arrive, and the teacher sees it from their own screen.
Everything a studio runs
If one of the three costs you money, tell us how much.
The first conversation is questions, not a deck.
