What is White Noise?
White noise is made up of many different frequencies of sound combined together at equal intensity. Its name is analagous to white light which is a combination of all of the different colors of light in the visible spectrum.
What is Pink Noise?
Pink noise is a variation of white noise that places emphasis on bass, or the lower frequencies of sound. Its called pink noise, because if you were to do the same with the visible light spectrum you would get a pinkish color.
What is Brown Noise?
Brown noise is a variation of white noise that places stronger emphasis on the lower frequencies of sound than Pink noise. In the light analogy this would yield a deep red color. But since the noise coincides with a mathematical model called Brownian motion it is instead called Brown noise after the physicist Robert Brown.

Ratings and Reviews
Great app for years deleting today
My husband and I have use this app for years with great luck. Today after an update it is completely changed will not stay on after the power goes off and you try to purchase it and it tells you your ID is incorrect when it is correct. You've turned a great app into a piece of crap. Too bad.
What happened?
I bought this app a couple years ago and now today all of a sudden it says I have the free version and I have to buy it. Wtf? It shows ads and won't let me use it with the screen off. What a scam!!!
