The only one of this kind, and works well!

That’s true that this is not super low priced, but it is the only app of its kind, it works well, and could have some serious health benefits for those of us who are sometimes forced to work at our computers until close to bedtime. I try not to do that, but some days you can’t avoid it. And, although those orange glasses can also help, I’d prefer not to have to wear funny looking, ill-fitting orange safety goggle glasses inside all night every night… I’d much rather try to improve the screen at night situation by using red/yellow bulbs in the house and a red screen filter at night.

After learning what studies say about how much blue lights disrupt melatonin and interfere with restful REM sleep, and is related to so many bad health conditions over the long run, I thought this seemed like a pretty basic idea for an app, and surely someone must have made one. So I looked for it for my iPhone, iPad, and Macbook. I found nothing for the iPad. For the iPhone, as of today there are a couple of specialty web browsers that red light/blue light filters… but you are stuck using that browser, and I really wanted the filter to wash over everything I was doing on my phone, even across and in between apps! (I imagine that may not be possible due to apple development rules, I don’t know). So this app accomplishes that on my Mac. I really like it and really have nothing to complain about. Recommended if you are concerned about being forced to use a screen at night.
