The design of the app is a cool concept which makes it feel like pressing a button to turn on a fan with 3 different speeds. But the rain sounds are too short because I could hear it loop every 4 seconds by listening to the pattern of the sound. And the app also is unable to mix the audio with other apps in the background. So unfortunately, it is not enjoyable for me.
I love this APP; it is very relaxing and mellow
