You can allow proper dark mode across the device with iOS 13, and it’s really easy to do so. The famous light background colors used across iOS turn dark with dark mode switched on. Apple’s own suite of apps support dark mode out of the box, and most popular developers of third-party apps will also upgrade their apps to support this as iOS 13 comes out. Dark mode is available for Apple devices running iOS 13.
