Apps and phones do all manner of fancy things right now but sometimes its the simple features which can be the most pleasant to use.
For example, we really like night modes and dark themes which reduce the glare in apps. So many screens are composed of a lot of white space or bright colours which can be a strain on the eyes, or especially troublesome in a dark room or at night. We're not suggesting you use your phone in the cinema though, that's always a bad idea.
Night modes are very useful and it was great to see Twitter adding an option to Android users a few weeks back. Now that same update has come to those on Apple's platform, for more darkness to spread around the world.
It's right there in the menu any time you want it and should be available as an update now.
