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.

Not sure how this obnoxious app has 5 stars, but every 10 days the app refuses to work until I go online and watch an ad. Fair enough, that would be enough to give a 3 star rating and no detailed review, but this last time it wanted me to watch an ad, it wouldn't show said ad and just refused to work. Saying "please wait for the ad" or something along those lines and never loading, and I was online - my wifi was working just fine on the xbox as I watched youtube. Mostly dim, not red enough.
