Creators of f.lux respond to Apple's Night Shift in iOS 9.3
Submitted by Frank Macey on
One of the key new features previewed in last week's iOS 9.3 beta is Night Shift. The basic premise is that blocking blue wavelengths of light after the sun has set improves sleep. This blue light is normally generated by iPhone, iPad and other mobile device screens, simulating sunlight. By reading iBooks in the evening or playing video games late into the night, circadian rhythms are disrupted. Night Shift addresses this problem, however it's by no means the first software to tackle the issue.
