If Apple introduces a larger iPad Pro with multitasking, this will shine more (blue) light on human eyes and create a need for platform-wide color temperature adjustment in iOS. At present, this is only available in a few apps. On desktops, it is available via fl.ux.
"When subjects read on the iPad as compared to the paper books ... people reported feeling less sleepy at night and less alert the following morning ... empirically, they also took longer to fall asleep on the iPad nights and spent less time in the REM phase of sleep. And the blood tests showed that on average, the brain's melatonin secretion on those nights was delayed by an hour and a half."
Why is this comment downvoted? Flux is the thing that I misses the most on my iPad. Moving from my Mac to my iPad at night is a painful experience due to the sudden influx of blue lights.
Anyone who uses iPad at night would benefit from blue light control in iOS. This is a larger group of people than those who are willing and able to jailbreak their iPad.
