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.

Other blue light filters don't block near enough blue light for my eyes, especially at night. I love the feature that lets me adjust the filter whenever I need it with a quick slide of the indicator. Thank you for creating this filter. I only wish I could use it on my TV.
