Dark mode is, quite literally, a skin you can apply to your entire phone that will turn most app backgrounds from white to black -- or at least dark gray. More specifically, dark mode essentially inverts the usual white background and black text to apply a black background and white text in apps and menus throughout your phone.
Reducing eye strain and making screens easier to read, especially at night, are two reasons why dark mode has become so popular, but it's also been hailed for looking cool.
You'll turn on dark mode by swiping into the Control Center (either up from the bottom or down from the top right corner, depending on which iPhone you have). Then just tap the button to toggle on the control.
You'll also be able to schedule dark mode to turn on only at night, and turn off again during the day. You'll be able to set those hours, as you can with night mode for Samsung Galaxy phones and Wind Down, Google's greyscale app for getting sleepy.

Will dark mode automatically work with all my apps?
Dark mode will work with systemwide apps on your iPhone, including Messages, Safari, the camera and photo gallery, the calendar, internal menus and Maps. Every app that Apple controls itself should support Dark Mode. However, third-party apps might not all work with dark mode immediately.
As with dark mode in Android 10, it's possible that iPhone apps that don't have a dedicated night mode or dark theme can get in on the feature automatically when you turn on dark mode in the settings, by inverting the colors.
Will it work for iPad?
For the first time ever, this year's iOS release won't power the iPad. Instead, Apple broke off iPadOS, a dedicated version of its operating system to work with the iPad's signature tablet features. However, iPadOS is based on iOS and will also feature systemwide dark mode.
Dark themes have certainly been around for years as third-party apps and themes. Unlike Google, Apple didn't say why it's looking into dark mode, though we're sure high demand was certainly part of it.
Apple doesn't have a track record of being terribly concerned about trends, often bringing out features years after competitors. It's always been much more concerned about getting things right than getting them first. It's also possible that Apple used MacOS Mojave as a test bed before moving on to the highly scrutinized iOS.
Apple didn't respond to a request for comment.
