Soundly Sleeping helps your sleep by reducing the amount of external noise you will be subject to.

It produces continuous, uninterrupted random noise that effectively cancels out other sounds. All you have to do is pick between the exact randomness that suits your audio source best: white, pink, or brown. Essentially the sound gets lower from first to last - simply try out what works best for you. Set your volume - not too loud, we don't want to hurt your ears - and have a good night's sleep!

You might also try the app in the following situations:

* On a plane and you want to relax or sleep undisturbed
* When repetitive sounds (like clock ticking or gentle snoring) keep you awake
* To mask out street noises if you live in a loud neighborhood

Give Soundly Sleeping a try if you have a headache, a migraine, tinnitus, insomnia, or you simply are looking for some privacy.

Try playing it for your kids if they won't fall asleep or your baby if it is crying.

Brown noise!

This is my go-to app to use whenever I don’t have the sound machine I use at home. The brown noise is perfect for canceling out low frequencies, like people driving or starting their cars. Other apps use recordings of noise that wake me up every time the loop is restarted, but Soundly Sleeping generates the noise based on an algorithm, so there are no disruptions to my sleep. The noise quality, along with a beautifully simple interface, makes Soundly Sleeping deserving of five stars!


Can’t sleep without it!

I love this app and brown noise is my go-to! I literally can’t fall asleep without it! I’ve also used it while traveling (planes & trains) and it blocks out a lot of background noise, letting me relax a bit more than otherwise - kinda like noise-canceling headphones, I suspect. Anyway - thank you for making this app - it has really helped me out!


Easy to use, does what it says

I didn’t have the glitch issue that other users mentioned, the brown noise seems to work fine for me. I go to sleep with it every night now. This is a great app that is really simple and easy to use. It’s been perfect for drowning out street noise now that I have my windows open again!
