Ratings and reviews

Verizon S22 Ultra. Android 14. One UI 6. January Google Play. March security update. I don't open the app everyday so I don't know exactly when this started, but every time I open the app it says that the application was built for an older version of Android. When I click on "Look for Update", there is no update available through the Play Store. Please fix this. I love your app. I've been using it for the better part of a decade, but I'll have to find a different one if it's gonna keep doing it

I downloaded based on an online article and was expecting a text with displayed results. That's not what this does. It displays colors and patterns so you can find issues yourself. It is actually fantastic for that, And I will probably use it instead of trying to find bright images online to test with. I took one star away though because there is no communication to explain how the testing is supposed to work. A readme or 1st use splash screens with instructions would really help your ratings.

Exactly what I need to see if my screen had anything burned into it. Fortunately most of it isn't noticeable during my normal use. Thanks for making it as easy as possible with little hassle. Though the point of there being no instructions or info for those unfamiliar with testing is a downside. No ads is a massive plus.
