Night Shift’s blue light reduction levels A color intensity chart shows that Night Shift barely reduces the blue light levels right before a user’s typical bedtime. In the morning it returns the display to its regular settings.Īccording to f.lux, the problem with Night Shift’s implementation is that they are not reducing the blue light levels enough. It then automatically shifts the colors in your display to the warmer end of the spectrum. Night Shift uses your computer’s clock and geolocation to determine when it’s sunset in your location. Studies have shown that exposure to bright blue light in the evening can affect your circadian rhythms and make it harder to fall asleep. In the post shared today, a member of the f.lux team shared some data to show why. While at first glance it appeared Apple’s take on adjusting the display’s color and lighting would ‘ sherlock‘ f.lux, that doesn’t appear to be the case. Specifically, lowering the output of blue light from a digital display to help make it easier for your body to fall back into a natural circadian rhythm. The general idea behind both systems is to alter the colors your display is outputting. Night Shift is Apple’s answer to the f.lux app. Both systems set out to enhance your sleep cycle by reducing blue light appearances on-screen, but f.lux may be the option that truly succeeds. In a new post shared on f.lux’s forum, a member of the team broke down why f.lux may be the better option over Apple’s similar offering. I’m going to give Night Shift a try, but I bet the ability to set apps to be excluded from the warmer tones will lure me back to f.lux pretty quickly.Released yesterday with the macOS 10.12.4 update, Apple’s Night Shift may not be having the impact on your display that it aims to. It will be fine for millions of users, but for those of us who want more control, f.lux will continue to be a good option. Night Shift, like many other macOS or iOS features, is much simpler than its third-party competition. You can adjust the warmth of things manually, for instance, in both, but f.lux also exposes a setting for what the temperature should be during the day. F.lux can be disabled for an hour or longer from its menu bar app, while Night Shift can be toggled on and off via Notification Center. 1 Both can be manually turned on before the appointed time. However, f.lux generally gives deeper customization options.īoth Night Shift and f.lux can run automatically between sunset and sunrise, based on your location. Customization & ScheduleĪt first glance, f.lux and Night Shift offer pretty similar options. If the screen is warmer, it’s warmer for all applications. as f.lux changing the color temperature of my display could cause me problems while editing photographs.Īpple’s Night Shift has no concept of exceptions. For example, I have Adobe Photoshop marked as an exception. One of my favorite features of f.lux is the ability to disable it based on what application is in the foreground. It’s also available for Windows and Linux. Update: A bunch of people on Twitter are saying Night Shift works on third-party external displays, so I’m not sure what this is about.į.lux, on the other hand, can run on a wider range of machines, virtually any external displays and older operating systems. If you are using an external display, it must be one of these to be work with Night Shift: Night Shift is available on the following Macs running macOS 10.12.4 or later: However, there are some pretty big differences between the two that may allow f.lux to stick around for many users. I’ve used it for years, and I find it hard to remember it doesn’t actually ship with a clean install of macOS.Īs is the case with any Sherlocked application, f.lux will have a battle on its hands now. Of course, savvy Mac users have enjoyed a similar effect for years by way of f.lux, a free Mac app that adjusts the color temperature of the Mac’s display based on time. With today’s release of macOS Sierra, Apple has added Night Shift to the Mac. It may be the placebo effect, but using up a device without - ahem, watchOS team - is jarring. I often am wrapping up the day one of these two devices pretty close to bedtime, and I find the warmer tones pleasing. I don’t know if it actually doing anything helpful, but I’ve enjoyed Night Shift on my iPhone and iPad over the last year. Some claim that this may help you sleep better, as blue light is harsher and can disrupt your sleep cycle, but the science is out on that. First released as part of iOS 9.3, Night Shift slowly shifts the color temperature of your screen to be warmer as the evening goes on.
