White Noise Lite
White Noise Lite is a great app that provides everything you need to listen to or create the perfect sounds.
For starters, the app comes with a large catalog with many options. You can listen to anything from frogs at night to a grandfather clock and even a heartbeat. All these sounds are perfectly looped, and you can even find and download more sounds for free.
Of course, if you’re feeling a bit more creative, you can record your own sounds or use the Mix Pad editor to combine all your favorite sounds however you want.
