It's basic  and to the point  which is exactly what I was looking for. Many of the other apps on the Playstore  come with a variety of options that I myself just don't need. It's simple  easy to use  very effective  and hasn't failed me yet! Overall  I definitely think I would recommend it to anyone looking to take some of the strain off their eyes at night  from the overwhelming brightness of your screen(s). My only suggestion  would be to find a way  to somehow also dim down the navigation buttons (back arrow  and menu.. ). Oftentimes  it's actually those that are the brightest. Just a thought!
