Ratings and reviews

Works well for me on my HTC one m8. I have a hard time keeping a regular sleep schedule. Using this app in the evening and at night (I use flux on my laptop, highly recommend flux!) Helps me sleep more at night. I read about how the "blue light" in backlit things and electronics mimic natural bright daylight in the brain somehow. I find it helpful, wish it were a little easier like flux, with its syncing up with your time and adjusting the blue light filter automatically in small increments.

I've loved using blue light filter, and have it on all of my devices. But now it keeps trying to charge me for a subscription which I didn't sign up for. Luckily, I didn't have my card attached to Google anymore. I don't know if it automatically started after a year, or if I accidentally hit the subscribe button. Either way, be careful about what you click in the apps these days. This sort of thing has been happening more lately (never before)...why my card isn't attached to Google anymore.

I, too, purchased the license key for the upgraded version and it is not being honored after an update. The version I have does not allow me to switch to dark mode. I can select it from the drop down menu, but nothing happens and the interface remains white. The white is really jarring in the dark (my eyes are super sensitive to light) and it's the main reason I paid for the license key.
