Could be great!

I love this app and use it often. I like the waterfall effect, but after a certain time it fades out then starts again. It is not looped and I cannot go to sleep by it. I’m currently using noise and have no problem with the ones I use. if you want to set the timer, it takes 4 touches to set it and get back to the main screen. Should only be 3.5 stars, but they do update it regularly and I expect these are things that will not be an issue in the future.

Great multi-purpose sounds app!

Nice selection of white noise, gray noise, and others. Also includes peaceful nature sounds plus mixes. The only thing that could make it any better would be some relaxing nature videos or animated gifs to go along with the sounds. Recommended!

My custom mix for falling asleep

I have used many different ambient sound apps in the past and really appreciate the quality of sounds included in this app. Not just white noise and gray noise, you have easily design your own favorite combination of these plus blue, light, pink, green noise and more. Plus, excellent nature, rain, and water sounds. Simple, clean interface.
