Very useful
I like this app very much. Even though at the beginning I hesitated a lot before paying for a white noise app, it turned out to be elementary for a good nap time for my baby. It was very hard for me to find a good routine to help my baby sleep longer, but the market white noise worked like magic, so all in all I do not regret buying this app at all since I've been using it at least twice a day every single day for the last 2 months :)
