Tint meter

★★★★★ Accurate within 3% using my Galaxy S8 measuring my window tint

★★★★★ This app is amazing! Thank you! Tl;dr: Take the highest number. If you can't figure it out the cops probably can't either. I have an LG-H910 with all current updates (2019 11 Aug 5:33 AM central-US on AT&T) The light sensor is EXTREMELY sensitive! I'd have to retake a photography class to be able to operate the camera manually. VLT is complicated by the fact that the glass and any film you put on your windows have two entirely different tint levels. This is further complicated by the fact that legal tint levels vary by state and country and laws change a lot. This is even further complicated by the fact that any tint level is legal (in theory) if it's installed in the factory. This is even further complicated by the fact that VLT is calculated using "industry standards." This is further complicated by the fact that different industries have different standards, and they are changing all the time. This is further complicated by the fact that some light will be reflected and some will be transmitted. This is further complicated by DPI... The sensor value's units don't matter as long as it stays steady when you're holding it steady.

★★☆☆☆ I tried to compare transparency of fabric. Fabric is between camera / sensor and mirror, flat on phone. No useful result, with / out fabric. Would be handy in fabric store / shop.

★★☆☆☆ Not reliable. Used it correctly said my tint allowed 37% light to go through, tint shop its only 10%.

★★☆☆☆ Worthless. Says my device doesn't have a light sensor.

★★☆☆☆ What unit of the number displayed?. I need to know VLT % for my windows. I measured window with no tints on it, and it gives me a reading of 1002.

★★☆☆☆ Didn't readings every time I use it, same place no light difference, and reset it many times. The app doesn't work
