Yesterday, the launch of iOS 9.3 added Night Shift to Apple’s mobile devices. It’s a really cool feature that might help make you healthier. Jailbreakers have enjoyed an app with the same functionality for years, but now it’s legitimate and poses less of a risk of completely jacking up your iPhone or iPad.
Night Shift gives you the option of warming up the light your display emits so that you get less harsh, blue rays before bed. The idea is that your screen’s usual output tricks your body into thinking that it’s still daytime, and that can make it harder to fall and stay asleep. So if you’re used to checking some e-mails or reading some news before you conk out, it might help you rest easier.
Here’s how to activate Night Shift’s soothing beams.
