Unexpected
I had rather frayed nerves and was looking for a nature sounds app when I stumbled on this. I would never have expected listening to some guy with an Essex accent to work, and I felt silly once or twice at first, but Ive now used it 4 times and it really does work to make you calmer and refreshed. Its more effective than a power-nap!
