Oh my goodness. For me, this is the perfect blue light filter. It doesn't have the strange washed out look that every other app I've tried has (I've tried a ton. I used to use Twilight, which for a while did what this one does, but it changed. Qhats great about this us that the filter just changes color which you can choose along with brightness and intensity. This app does what it says, it blocks blue light. Its great.

Simple easy to use blue light filter app. Sometimes I have to shut it off in order to make selections or click on links on certain web pages that's really annoying. It would be better if it filtered the pull-down options bar too. Going from the screen being really dark to that super bright screen portion is not pleasant. Otherwise the app is easy to use and works great.

I've noticed a change in how much faster I fall asleep at night almost instantly after using this app. I like getting to choose a filter color. Being able to switch it on and off from the top of my phone without opening the app is a major plus. I only knocked a star off because on some apps the screen will flicker, namely on discord. Otherwise its perfect and I've seen no drain on my battery from it running.
