Apple recently added Night Shift to macOS, which changes the colour temperature of your screen based on the time of day in the hopes that it will help you sleep better. Before the launch of Night Shift, f.lux was the go-to tool for doing this. Let's see how they compare.

Mac: If you're a fan of Night Shift on your iPhone, or F.lux on your Mac, you'll be happy to know that Apple's rolling out an update to macOS today that adds the time-based colour-shifting feature to your Mac.

Android (root): F.lux is one of our favourite tools for automatically changing the colour temperature of your monitor based on the time of day. Now, it's arrived on Android, but you'll need root to use it.
