This app has great sound. I love all of the different choices you have from gentle rain to big storms. The gentle rain end of the spectrum is nice when you have a quiet room, youre just looking for a little sound to lull you to sleep. The heavy storm end of the spectrum is nice to have when youre trying to work and youre trying to drown out noisy toddler toys. Great for my needs, and the sound quality is better than any of similar apps Ive tried.
