F.lux says it is ‘original innovator’ of nighttime display color tech, asks Apple to open Night Shift API

“Developers behind popular screen brightness and color control software f.lux issued a formal statement in response to Apple’s debut of ‘Night Shift’ in the latest iOS 9.3 beta, calling on the tech giant to allow a proper version of f.lux into the iOS App Store and open API access to Night Shift’s display management tools,” Mikey Campbell reports for AppleInsider.

“In its carefully worded response, f.lux lauded Apple’s Night Shift beta launch, an iOS feature that automatically shifts display color temperature towards the warmer end of the spectrum to ease physiological effects of being exposed to cold blue light at night,” Campbell reports. “‘Apple’s involvement in fixing this problem is a big commitment and an important first step,’ writes f.lux cofounder Michael Herf.”

Campbell reports, “‘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,’ Herf says.”

MacDailyNews Take: Good luck, f.lux.

Apple’s iOS 9.3 may save your eyes, help you sleep at night by reducing blue light – January 11, 2016


  1. F.lux didn’t do the original studies about the effects of blue light and sleep.’
    They had a good run by filling in a gap in the Android market, but calming they own warm light is like posting “First!” in a blog post.

  2. I believe F.lux tried to release an iOS version but Apple blocked it because it required access to non-conventional APIs. I have used F.lux on my Mac for years because I used to stay up much later. I set it to slowly warm my display over the course of an hour at night, and you don’t even notice it happens. But it always amazed me how much brighter it was if I turned off F.lux for a few seconds! Wow.

    This day-night adaptive technology should have been built into HDTVs and computers long ago.
