Two screens, two different jobs
The big screen is the show — everything the room shares. Your phone is the controller and the private channel. Neither shows you the other's half, and that is what makes it work.
On the big screen
TV, laptop, projector — anything with a browser and speakers.
On your phone
No app. A browser tab and a four-letter code.
What you can change
Everything here is one switch at setup. Defaults are the ones we play with.

A minute of setup, four letters for everyone else, and the host takes it from there.
