This latest update takes away the best part of the app: the simple, fixed notification bar shortcut to turn the filter on or off. The notification bar shortcut is now obnoxiously large, the button to actually turn the filter on and off is tiny, and I really, really don't need a giant capture screenshot button. The shortcut now moves around as well so it's harder to just tap the filter on and off. After 4 years of daily use across two phones, I'm uninstalling.

I have eye tissue damage from childhood and I am giving this app three stars because it effectively dims the screen sufficiently and offers a range of shades to tint which I appreciate though I never use more than two. But it is difficult and confusing to set up the schedule option (one of the reasons is because it's in military time) and also the screenshot without the filter button has never worked for me. Being able to take easily readable screenshots for other people is important for me.

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.
