&gt; If they&#x27;d open source it, users would be able to compile for their own devices just fine.<p>&quot;Just download this repo &amp; compile for your own device&quot; really isn&#x27;t a solution for most people.  There&#x27;s a lot of people who would love to use f.lux on their devices, but wouldn&#x27;t have a clue how to compile something with Xcode.  Even offering the binary to sideload is a poor solution - what about people who don&#x27;t own a Mac to connect their phones to?<p>For the maximum number of people to benefit from this, whether it&#x27;s f.lux or GoodNight or another solution, it needs to be built into the OS (like Samsung has with Reading Mode) or on the App Store behind a big easy button that says &quot;Get&quot;.  That&#x27;s what f.lux is campaigning for.
