Someone finally gets it! It doesn't time out. It has no white bits. It doesn't strobe. The settings are black. Even from 100% brightness, it safely closes to your home screen without blinding you. It's simple perfection for all your therapy, circadian rhythm, and night light needs without the glaring mistakes of the others! Highly recommend!

Works beautifully with one exception. The adjustment bar defaults to fully expanded. This has the detrimental effect of dimming the screen randomly. As you move your phone around the app it will, of course, occasionally switch from portrait to landscape (& vice versa). As this happens the adjustment bar adjusts as well, & in landscape mode blocks much more of the screen, dimming the usable light. I want to like this app, but find that this design flaw keeps me using the "Red Light" app.

Good red light for paperwork when you don't feel like blinding yourself with the light on the inside of your car. For what it is and it not having any ads makes this a 5 star app. Yes they could tweak the app to improve it, but it is free and they make no money from this app. So all things considered this app is by far the best red light app on Google play.
