Works, but two complains 1: Upon starting, my phone asks if I am sure I want to crank the earphone volume up to 100%, indicating that some app tried to do so. 2: It stops when the screen goes to sleep (after 30 seconds in my phone) making it useless for ambient sound continuous blocking.

Great for my tinnitus but... Needs the ability to run in the background with accessible controls on the task bar. There is another app that does this but IMO the pink noise doesn't sound as good as it does with this app. Otherwise nice job!
