Apple have released the latest software update for their handheld devices range, iOS 9.3. This release introduces Night Shift, an optional mode designed to reduce the potential for sleep disruption when using Apple devices at the end of the day. Further changes include the ability to password-protect individual notes in Apple's stock Notes app, and improvements to the News and Health services.
Regarding Night Shift, Apple published the following on their website:
"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".
iOS 9.3 can be installed now on compatible iPads (second-generation devices and onwards, although the Night Shift feature will only work on fifth-generation devices and onwards). To find out how to upgrade to the latest software release for your iPad, follow our step-by-step guide.
