Tint meter

Worthless. The directions are worthless. No matter what I did I couldn't get it to work. Over two days I tried everything. I tried inside the car, outside the car, windows rolled up, windows rolled down, literally every which way possible, even Google and YouTube, to get this dang thing to work but it's not happening. MAYBE if you have some type of experience using something like this or if by some chance you have a certified mechanic friend who can show you how to use it then just skip it.

The best tint meter app..I have galaxy S10+ and it works like a charm....Highly recommend this app. Only one that actually works!! others who have tried and not work I suggest getting galaxy S10+.. You will not be disappointed. I've been tinting for 31 years and have been using this app over 4 yrs with no problems at all. Your screen needs to be facing towards the window.. if you have different readings then you are facing screen in towards the car. face screen outwards..little tricky to operat

love it! 100% accurate! I'm currently replacing my old tint (with unknown %) and got some new tint samples from different manufacturers to compare and match the good (night) vision of the old one. Was super hard comparing just by eyesight, so I used that app to measure the tint. All samples matched 100% the exact manufacturer specified tint value with this app's results. Keep in mind that if you measure on your window glass, the glass might add some extra % if it's slightly tinted. Also make sure to hold the phone correctly - display towards the glass, since your light sensor is next to your ear speaker.
