Color Filter is a free screen-dimming tool for users who have the habit of using their devices in the dark. Not only does the app reduce eye strain, it also helps conserve battery life. However, take note that using this program can cause unresponsiveness or crashes.

Helps protect your eyes

Frostnerd.com’s Color Filter includes several screen color overlays or filters and provides the option to adjust the opacity of your selected overlay. These filters can be enabled or disabled by tapping the eye icon on the top right corner of the screen.

If you want, you can even apply your selected overlay on your lock screen or upon boot up. While the app’s strengths lie in its intuitive usage, its weaknesses revolve around stability problems, lagging, and other technical issues. Taking screenshots is not recommended, too, as images will appear darker.

Problems with stability

Overall, Color Filter is a great app for minimizing eye strain without it putting a heavy toll on your device’s battery life. Here, you can choose your preferred color overlay and adjust its opacity to your liking. Unfortunately, this app is known for its stability issues and unresponsiveness.
