Instagram, which updates the iPhone application, is now adapting to system-wide, dark mode on devices running iOS 13. This feature is especially necessary for bright applications such as Instagram, which will relax the eyes at night.
Even though the dark mode is beautiful, just like for Android, the iOS version does not include any transition to dark mode. Instagram, which is a system-wide adaptation to dark fashion, is a click away from its competitors.
