Nice Background Noise

Nice free content, but much more available with payment. The slection is decent, but I would have been much happier if there were more options available for free.

Lovely App

This is great! I enjoy being able to have these background melodies. I like this lovely app that I can hear soothing sounds to accommodate my moods. Wish the developer could keep updating.

If you want relaxing sounds or white noise in the background, this app does the trick! Would be great if they came out with visual to go with the audio.
