I have to give this app so many thumbs up it would be ridiculous. I have been studying for the bar exam (licensing exam for attorney’s) the past few months. I have to have background noise when I study because come the day of the exam, dead silence is non existence. This gives me some background noise without being overly distracting. It is relaxing and calming and helps me get through my day. I love that there are a variety of sounds to pick from and you can mix and match them. I personally love the piano with the rain storm, but the possibilities are endless. Include the concentration and relaxation “brain waves” and you are golden. Love this app to the moon and back. I have it on my phone and my laptop!
