I use something similar and I noticed that I become sleepy faster than without the app. I think it would be interesting to study the effects of a device with low brightness and an app like that (that filters out blue light). It is still a light source directed at your face, but you don't need a bedside lamp.
I use f.lux. The color temp of your screen changes depending on the time of day.
