Green Screen is a free app to make your Android phone a greenscreen, or a chroma-key device. It is the best and fastest way to create a green screen in your Android device.

To create the effect, just use a solid-colored background (like green), snap a photo, and this will remove the screen color and replace it with a cool background.

This app is a powerful and fast tool to remove the color from the screen and replace it with a different one. It is a very easy-to-use app that works with any background color.

This app includes a built-in eyedropper to click on part of the photo to set the background to any color.
