As Im writing this for the second time. This app is stupid, its either dim or way to bright. I have the iPhone 4S and when I installed this so I could read while my daughter goes to sleep its way to bright! I also noticed when I went into my phone settings the brightness was turned all the way up, you might as well just do that turn the brightness all the way up, I like mine low or on auto which its always on. This app is not worth the download
