Great! Tinnitus reliever :o)

Update:
Great new update. I use it for tinnitus, it helps me get to sleep, and the extra field plus the micro adjustments are excellent. Finally works on my iPhone 6s+ with iOS 9x.

This app definitely provides the customizable background noises that help me get to sleep. Ive been suffering with tinnitus over the last few years and this application helps alleviate the symptoms when I try to go to sleep.
