Night Shift in iOS 9.3


Many studies have shown that exposure to bright blue light in the evening can affect your circadian rhythms and make it harder to fall asleep. Night Shift uses your iOS device’s clock and geolocation to determine when it’s sunset in your location. Then it automatically shifts the colors in your display to the warmer end of the spectrum, making it easier on your eyes. In the morning, it returns the display to its regular settings. Pleasant dreams.

Surprisingly, it is configurable.

Juli Clover:

The Night Shift feature appears to be limited to iOS devices that have a 64-bit processor.

Previously: Sideloading f.lux on iOS.

Update (2016-01-15): f.lux (via Hacker News):

Rather than suggest simple answers, our mission is to enable f.lux to advance the science, while providing customized solutions for each person. We intend to make f.lux better in every way than the app we designed back in 2009.

Today we call on Apple to allow us to release f.lux on iOS, to open up access to the features announced this week, and to support our goal of furthering research in sleep and chronobiology.

Update (2016-02-18): Steven Aquino:

Night Shift strikes me as one of those technologies that isn’t intentionally built for accessibility’s sake, but works well enough that it also has relevance to people with disabilities.


Secondly, all the consideration I’ve put into the brightness and contrast of an iOS device’s screen leaves me longing for a system-wide dark mode.
