Menu wall
Two or three screens side by side, each a section of the menu, kept in one visual system.

What the screen is for
Two or three screens side by side, each a section of the menu, kept in one visual system.
A board you change at the start of service, not one you queue with a designer for.
The information you are obliged to show, legible and current, without a laminated card.
Templates
Landscape, portrait and square, in dark and light, rendered by the app's own engine.
Questions
Yes — build a layout for each screen and register all three. They share your typefaces and colours, so the wall reads as one board.
Open the console on your phone, edit the text widget, publish. The screen swaps within a few seconds without restarting.
That is the intended use. The screen is held awake, the layout is restarted after a power cut, and the app comes back on boot.
One Android device, one install, no account. Nothing to cancel afterwards.
