Owners of recent MacBooks Pro and Air can enjoy True Tone, a great technology that uses an ambient light sensor to match the color of the Mac’s display to its surroundings. True Tone mimics a white sheet of paper, which reflects the ambient light. The goal is to avoid a cold-blue screen when you’re in a nice, warmly lit room.

True Tone is a wonderful feature, and really makes everything look better. But it’s only available on new Macs. Today we’ll see how you can fake it on older computers.

Apple may have killed the anti-eyestrain app F.lux on the iPhone, in favor of their own ‘Night Shift’ mode. But fans of F.lux on the Mac and PC will be happy to know it is now coming to Android.

When iOS 9.3 announced Night Shift, a new mode that makes it less likely for your device’s light temperature to disturb your sleep schedule, many noted that it was virtually a carbon copy of F.lux, a Mac and jailbreak iOS app that we’ve previously called a Mac essential.

Now, the developer of F.lux is commenting on Night Shift, and while he’s broadly supportive of Apple’s move, he still wants Apple to allow F.lux on the App Store.

Those who live their lives glued to their computers love f.lux, a cone-saving app that automatically adjusts the color balance of your Mac (or jailbroken iPhone or iPad’s) display at sunset or sunrise so it’s easier to read.

For f.lux lovers, though, the app just got a lot better on the Mac. Previously, F.lux’s only consideration was whether the sun had risen or set, but now, it takes into account your body’s circadian rhtyhm. You can actually train f.lux to take into account when you go to sleep and wake up.
