I realize that f.lux has a small and passionate group of users. And if it works for you -- use it!<p>But I find the constant drama around the product to be absurd.<p>A wealthy California couple that previously got famous for refusing to give their fingerprint while attempting to buy a new BMW in cash spends six years making this product? And now their complaint is that you can&#x27;t use your fingerprint to authorize installation of it via the app store?<p>The cherry picked research and weasel word phrasing and the constant bugs and updates -- all so I can get used to it and then lose access every time Apple releases a new OS? I&#x27;m sorry, but I just don&#x27;t believe that running a piece of software is going to prevent acne. Though that&#x27;s what their website says.<p>There are other ways to reduce the amount of blue light entering your skull in the twenty minutes before bedtime. You can turn down the brightness. You can turn on lights in the room. You can turn off the device altogether and make love to your partner, assuming you can get him or her to turn off the damn phone, too.<p>But f.lux -- it&#x27;s time to get real. You&#x27;ve had six years. You haven&#x27;t managed to get a single TV, Device, Platform Vendor or Lighting manufacturer to license this &quot;patented&quot; product of yours. The attention game isn&#x27;t working. Find a dev who can fix the product and find a product manager who can sell it.<p>Edit: I&#x27;d appreciate refutation in lieu of downvotes. Blame Apple all you want but where&#x27;s the Android version? If there were so many significant health benefits to be had, you&#x27;d think they&#x27;d be working on hitting the larger market instead of playing this narcissism game. At least get the damn thing running on a Kindle if you&#x27;re worried about bedtime reading. But nope, just Cydia and constant drama.
