    F.lux, popular Mac software that adjusts the color of your computer's display to adapt to the time of day, has been released for iPhone and iPad in beta outside of the App Store. The app can be downloaded and side-loaded on iOS 9 devices using Xcode 7 on a Mac running OS X 10.10 Yosemite or later.

    F.lux will adjust your iPhone or iPad display to appear like sunlight during the day, and warm during nighttime hours to avoid looking at a bright screen. The app has settings to adjust the brightness level during the day and night, and you can also configure a time that you normally wake up each day.

    Apple does not allow developers to access the Private APIs that f.lux requires to work on iOS, so the app is unlikely to appear on the App Store unless that policy changes. Since the app is side-loaded, there are no automatic updates, so the beta performs a daily update check and will display a message if a new version is available.

    How to Sideload F.lux on iPhone and iPad

    F.lux has provided step-by-step instructions on how to sideload the app on iPhone or iPad.Download and install Xcode 7 from the Mac App Store
    Download F.lux for iOS, unzip and open the "iflux.xcodeproj" project in Xcode
    Open Xcode > Preferences > Accounts and enter your iCloud or developer credentials
    Under Targets > iflux > General > Identity, give the Bundle Identifier a unique name
    Under the same Identity > Team menu, select your iCloud account or Developer profile
    Next, connect your iPhone or iPad to a Mac using a Lightning cable and follow these steps:
    From the Xcode Product menu, choose Destination and select your iOS device
    Push Cmd-R when you're ready to have f.lux
    When you first run, you'll be prompted to open Settings > General > Profile on your device, and trust your developer account
    Run again, and allow location and notifications -- the app needs to be able to constantly communicate to run well

    F.lux for iOS was developed by Michael Herf and is free for iPhone and iPad. The app was released for jailbroken iOS devices in late 2011.

    As of right now, no-one should have a reason to jailbreak anymore.

    I credit F.lux for helping me get better sleep.

    It hasn't been 100% of the reason, but it's a major factor.

    Is there a way to do this on a Windows machine?

    You're joking right? There are so many reasons to still jailbreak

    yes, you sell it an you get a mac.
    I guess you could do a virtual mac on the windows pc.

    calm down and go home
    more placebo than anything IMO, but is nice not to glare at the screen before bed.

    OK, downloaded the Xcode project and... it's a binary wrapped in enough barebones code to get it to compile.

    Honestly, I'm a little creeped out. I get that the app is patent-pending and they've got some trade secrets to keep secret and all that, but the whole reason I trust Xcode side loading versus jailbreaking is so I can make a cursory audit of the app and make sure it's not phoning home or doing anything creepy. This is especially true for an app that can only exist using private APIs. Call me paranoid, but one of the reasons I use my phone as much as I do is because I have that reasonable expectation of privacy/safety from key loggers and the like.

    All that to say, how safe is installing this? Anyone have any experience?

    I don't think you can do that with the free Xcode dev account since it doesn't let you distribute your app unless you have connected it physically to Xcode before in that free account afaik. You can always use a virtual mac on your pc. There are other ways but they are not free.

    To add to this, if you know someone with a dev account, they can probably put a build up on TestFlight for you.

    Apple could just make a dark mode like on OS X and turn it on based on time of day. Solved.

    Is anyone else having trouble finding the Targets menu or whatever the steps are talking about? I can't seem to find it in Xcode 7.1.1.

    Except the colour cast of the screen in dark mode will still be blue, simulating daylight and will thus still mess with your body.

    I don't understand why this isn't built in to iOS.

    Glad to see this on a non-jailbroken device, finally. I do miss the force-touch feature that GammaThingy has though.

    Brilliant. I’d still pay for that if and when it’s released officially.

    The webpage for f.lux says "Patent Pending" at the bottom, so that'd be my guess. :/

    The f.lux developers have a good reputation and the app has been available for many years without giving problems. 100% security is not there even for app store apps (as recent history have shown). But you are right, from great powers comes great responsibility. In the end everybody will decide for himself. ;)
    That said, I have it on my iOS devices right now,installed via xCode. It's working fine.

    I've been using the open-source GoodNight for this: https://github.com/anthonya1999/GoodNight

    I wonder if f.lux offers anything over GoodNight?

    I'm running f.lux on my Mac, so I at least trust the author of f.lux enough for a non-open-source app on my Mac. However, all other things being equal, I'd prefer to use an open-source app, assuming functionality is the same.

    I wish Apple would incorporate this into iOS, or allow F.lux into the App Store.

    Really great news. Anyone has suggestions for other useful apps that can be sideloaded this way please? For example; a YouTube client to replace one of the great apps that Apple/Google banned lately?

    I was really excited when Apple announced this feature on WWDC last summer, but it turns out no one else is.
