Not worth the money, lacks basic features

I dont remember what I paid, not much. But the paid version of the app doesnt have the basics I would expect, and that I do get from other apps. Namely, the ability to play more than one color noise simultaneously, and to play under other audio app. I would like the oscillation, except instead of modulating itself, it turns my headphone volume up & down! Every other white noise app I have is a better product at a better value.
