Android: For whatever reason, Google has yet to give its Android YouTube app the long-awaited update that finally unlocks dark mode. iOS users can dark mode. Web viewers can dark mode. But Android? It's the light side or nothing (at least, as of when we wrote this article).

Using a "dark mode" on your favourite website, app or operating system feels great. It's perfect for dark rooms or aeroplanes, when you need to conserve your battery a little, or you're just tired of having sore eyes from staring at a screen for hours.

I'm a tremendous fan of dark modes. They're easier on your eyes and your computer's battery, and I think make using sites and apps a lot more pleasant. Unfortunately, not every site offers a dark mode (this one included). However, this week I came across a web extension that can make the magic happen anywhere you want it to.

Dark Mode, a feature that replaces your usual black-on-white display with white-on-black, is easier on the eyes and makes you feel like you own bitcoin. The site Dark Mode List will show you all the macOS apps, iOS apps and websites that support the feature and tells you how to enable each one.

I love using Night Mode for apps and sites whenever possible. Darker colours are easier on your eyes, even during the daytime, and you can even save a little battery power on your laptop or smartphone by trading a bright white screen for something a little more subdued.

Reading your phone in bed is ruining your sleep schedule. But if, like me, you do it anyway, learn to do it without feeling like you're staring into the sun (or annoying your sleeping partner) by enabling "dark mode" on every app that offers it.

A while back we showed off a little trick to enable YouTube's secret dark mode. Now, there's an official way to opt into the new look.
