What devices uses @1x, @2x and @3x?

Question

I am curious what iOS devices uses @1x (I know this should be empty), @2x and @3x. When I search on here, I get uncompleted answers like: What should image sizes be at @1x, @2x and @3x in Xcode? Here I do not see the iPhone 7 or every iPad resolutions. I need to know this because my app requires image downloads and I need to know what size that image needs to be, depending on the screensize. I download it from my server and I would like to know what format (1x 2x or 3x) I should use.

Thanks.
