Tint Meter is a free Android app developed by Nextappsgen, under the category of Travel & Navigation. This app is designed to check the transparency of car windows in terms of visible light transmission (vlt) percentage. With the help of the light sensor of your smartphone, Tint Meter determines the transparency of the glass with or without a film.

The app is easy to use, and it does not require an internet connection. Once you open the app, you need to place your phone on the car window and select the external or internal illumination measurement. After the measurement, the app will show the vlt percentage of the car window. Tint Meter is a useful app for car owners, especially those who want to check the legality of their car window tints.
