Staring into bright blue lights all night can be bad for your sleep, that’s why I’ve been running F.lux on my Mac for the last couple years. F.lux is a freeware utility that slowly makes your computer screen emitted light less blue and more orange as the sun sets. I don’t have any of my own hard evidence to back up F.lux’s claims, but my Mac screen seems less harsh at night, and falling asleep has been easier since I started using it.
Unfortunately, these days I tend to use my iPad and iPhone more than my Mac before bed, and F.lux (or a utility like it) is not available on iOS due to current App Store restrictions. For a brief time last week, F.lux offered a way to sideload their app on iOS devices through Xcode. However, Apple quickly shut them down. Given the sleep benefits and Apple’s push into health related software, I hope Apple finds a way to open F.lux related APIs in iOS 10 or provide their own solution.
