The web tool will switch the position of latitude and longitude in text. It's a common issue in GIS industry as there's no agreement which order is the correct one (and tools/software want one or the other). The initial Show HN dicussion derailed into which order is the correct one, second-guessing why the tool could be any useful to anybody and it went downhill (well, flagged) from there.
Hitting flip simply takes the entered (or default) coords and displays two columns of info below, maps and data about the location. Hitting it again doesn’t toggle anything further. Slightly confusing at first.
Are you on mobile? There is a second column with flipped coordinates that is offscreen if the phone is in portrait mode. I suggest that you try to browse the page in landscape mode.
