Apple approves f.lux-like app ‘FlexBright’ [u]

By , Mar 7, 2016


Apple has approved a new app called FlexBright, which allows you to manually adjust the display temperature of your iPhone or iPad. That makes this one of the first third-party apps to make it into the App Store that provides a feature similar to iOS 9.3’s Night Shift mode.

It’s interesting that Apple would green-light a title like FlexBright, given its history. For those who aren’t familiar with the story, last fall the iPhone-maker asked the developers of f.lux—a long-running app with similar functionality to FlexBright—to shutdown their iOS work.

Update: the app has been pulled from the App Store. The developer mentioned on Twitter that Apple hasn’t provided any reason for removing the app.

The way FlexBright works is a little bit different, though. The application runs in the background on your iOS device, and sends you a notification prompting you to change the temperature settings on your display based on either the time of day, or by custom times you assign.

FlexBright has a smart calculator that monitors your exposure to blue light throughout the day and will alert if you if eye fatigue is detected. Put in your bedtime and FlexBright will monitor your exposure to blue light and alert you to reduce brightness when it gets closer to your bedtime to minimize blue light effect on your sleep cycle.

It would seem that FlexBright has been in the App Store for a while now, but only recently received its Blue Light Filter and Dark mode features via a 2.0 update. It’ll be interesting to see if Apple allows the app to stick around now that we’re getting very close to an iOS 9.3 release.

If you want to check it out, FlexBright is available in the App Store for $2.99.

    So they shut down side loaded f.lux for iPhone, make their own version of it, and then approve some random app that does the same thing? Ok Apple.

      The difference being, f.lux uses private API’s which FlexBright doesn’t in favor of a native Objective-C library.

    Seems a bit much to pay for when ios9.3 is just right around the conner.

      It supports iOS 7 & 8 not only iOS 9.3, and non 64bit devices.

        Yeah that may all be true but if i was on an older firmware id jailbreak. However, i suppose if your not jailbroken buy the app. But im jailbroke and on ios 9, so that just iant for me.

    Sunrise app icon? What a shame..

  • Mr_Coldharbour

    Not sure if this post mentioned it, or maybe I missed something, but does this provide a system-wide effect in light warmth/temperature?

  • Please tell me that’s not the actual layout of the app. It’s like a five year old designed it.

    • My thoughts exactly ha

      There are lots of talented coders that know nothing about good design. And talented Designers that know nothing about Code. In my case, I’m an iDB reader…

    What’s the point pay for an app when in a two weeks are for free in a OS 9.3?
