It's probably not a good idea for a long run, but my daughter for a few years now is put into sleep with noise generated from the app. It was a life saver for us, to help her get to sleep. Otherwise we are too loud for her, or neighbors. I put the preset to a triangle starting high on red and low on violet. Also options to a delicate amplitude pulsing.

It is also very helpful to go to sleep if it is too loud also for adults.

It is a perfect app for me.
