About this app

Eyes feel tired during night reading on the phone?

Have trouble in sleeping after long time watching phone screen?

That is due to blue light. Blue light from your phone and tablet screen is the visible light spectrum (380-550nm) for circadian regulation. According to the scientific studies, exposure to blue light imposes serious threats to retinal neurons and inhibits the secretion of melatonin, a hormone that influences circadian rhythms. It is proven that reducing blue light can greatly improve sleep.

Blue light filter is used to reduce blue light by adjusting the screen to natural color. Shifting your screen to night mode can relieve your eyes strain, and your eyes will feel at ease during night reading. Also blue light filter will protect your eyes and help you sleep easily.

Really appreciate that I don't feel intense pain as I look at my screen. Edit: Would help if there could be an additional explanation about how "drawing over apps" refers to the filter going over everything and how we might have to turn it off to allow the play store or other apps to work. I know we turn on the permission first thing upon downloading this, but I misinterpreted the "drawing over" issue from the play store as a minimized screen like YouTube.

The app keeps turning itself back off every time my screen locks. I have the settings to allow it to use background data, and it still does it. I keep having to go back in and turn it on way too often. And sometimes it interferes with my other apps working properly. Please fix this or I will find a different app. My eyes are too sensitive to the blue light and it sometimes causes migraines and seizures, and I need the filter on all the time.

Better than other filters I've tried. It gives you options for how dark or light you want it. Fairly unobtrusive; does the job without a lot of annoying ads. Biggest problem is that I can't update other apps when it's running, and it's also caused some issues in games. But it's easy enough to turn it off and back on again.
