Ratings and reviews

This app was great, I used it to correct over-saturation on my screen for almost four years based on a Reddit recommendation. I paid the annual fee to open up all the features. Then within the last 6 month's, I got warnings from my phone that I had to allow its use because it was collecting data. There's no reason for that. Un-installed, subscription cancelled.

This app worked OK for a while, but it always becomes disabled for no reason. Not only that, but you have to watch ads every couple weeks to keep it free, yet the ads almost never load. So I can't even use the blue light filter at all since I can't complete the prompt of watching ads. Uninstalling. Sick of repeatedly having to mess around with my settings to turn it on when it toggles off, and sick of the ads not loading.

The ideas are definitely there but after giving the permission it needs to run in the notifications bar, it doesn't realize it, when it already is approved. Very poor programming for this. Also different GUI that doesn't make a lot of sense. They don't have amber/orange as a color which is the most common blueloght filter. Uninstalled app.
