I love this app!

Ear plugs never worked for me to drown out external noise when trying to sleep. This app does a fantastic job. Also helps me get to sleep when Im agitated or restless. Soothing, like Im lying beside a waterfall or rushing stream. Much improved sleep for $.99 - one of the best apps Ive bought this year.
