Night Shift (software)

Night Shift is a built in software feature of iOS and macOS. It was introduced into iOS in iOS 9.3 and into macOS in macOS Sierra 10.12.4.[1] The feature changes the color temperature of the display towards the yellowish part of the color spectrum[2] that reduces some of the blue light from the screen.[3] Apple claims that the feature may help users have a better night's sleep by filtering blue wavelengths from the display.[4] The feature is similar to the functionality f.lux provides.[5][6]

Compatibility

The Night Shift feature is compatible with all 64-bit iOS devices running on iOS 9.3 and above[7] and Macs from 2012 and later running on macOS Sierra 10.12.4 and above.[8]

Functionality

The feature can be turned on in Settings (in iOS)[9] and in System Preferences (in macOS)[8] and can be toggled on or off manually in the Notification Center (in macOS)[10] or in the Control Center (in iOS).[2] The feature can be enabled or disabled with Siri in iOS[7] and macOS.[11] The feature can set so it is enabled at sunset and turn off at sunrise (the default) or turned on and off on a custom schedule.[2] The feature when set to enable at sunset and disable at sunrise relies on the user's approximate location to determine the time of sunset and sunrise.[12] The user can also customize the intensity of Night Shift in Settings (iOS)[2] or System Preferences (macOS).[13]
