With Moonscreen, you can adjust the brightness of your smartphone screen in an incredibly easy way by simply sliding the bar until the brightness is as you'd like it. You can even go below your screen's minimum brightness levels, so your eyes won't suffer and you can use your smartphone no matter the circumstances.
Besides adjusting the screen brightness, you can also add color filters with Moonscreen: yellow, blue, red, and green. You can also use your camera's front and back flashes (if you have them) as flashlights, and you can take advantage of shortcuts to lower the brightness to the minimum, activate night mode, or turn on the flashlight with just one movement.
Moonscreen is a very useful app that you can adapt to your smartphone usage, changing your screen's brightness to your preferences in just a few seconds.
