How do I turn on dark mode in the Reddit app on iPhone?

Reddit has a mode for viewing in low light environments, how do I activate it?

Reddit does have a Night theme for low-light situations. Turn it on in Settings (tap the Reddit icon in the top left corner of screen, then look for Settings at the bottom of the menu that comes up). In the Theme section you can set your theme to Night all the time, or you can have Night theme automatically turn on when it is actually nighttime with the toggle below.
