I am using Ruby 3.0 and I would like to know how to check if the users screen is portrait-flipped (or upside down) assuming the user only has 1 screen.

I would say that since Ruby is a server-side language, you will need to rely on a browser-side tech first, such as JavaScript, as getting the size and orientation of a screen would be done browser-side.
There are probably JS libraries for that if you prefer, but here are some docs to detect device orientation on some browsers:
- https://developer.mozilla.org/en-US/docs/Web/Events/Detecting_device_orientation
- https://developer.mozilla.org/en-US/docs/Web/API/Screen/orientation
With the value obtained in JS, you would then do some AJAX call to your ruby code to send the value to the backend. (you would create a API controller that receive orientation data and update your ruby objects, or whatever you want to do with the orientation)
I hope this is helping you go in the right direction!
