Since that time I’ve used it on all my family weekend getaways, business trip and sometimes even for a Saturday afternoon nap at home.
I personally have three installed on my iPhone. “Sleep Machine” (lite) which let’s you mix a few different relaxing sounds together. “White Noise Lite” and “a pocket Falls – lite” which has a nice waterfall metaphor interface.
But there’s probably at least hundred different apps to try out on your own.
Next time you go on a biz trip or are on a weekend getaway in a hotel with a room right by the elevator – a white noise app can help you sleep like a baby.
