Screen Filter free

As you may or may not know, using your smartphone or tablet in dark places can harm your vision even if you reduce your screen's brightness. Screen Filter free is an app that helps you adjust the brightness and color temperature quickly and easily.

This app lets you change the color of your screen by applying different tones that you can modify to get the perfect brightness for every situation. For example, you can apply a red tone and then add green or blue to create a contrast that lets you read your screen at night.

All you have to do is adjust the different colors of the app, one by one. In the lower part of the screen, you can see each color bar in a group, making it even more convenient to adjust your screen's color filters and help your eyes relax a little bit.
