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.

It’s What an App Should Be Like

This app is simple, free, and VERY user friendly. With the other sound apps on the store, this one is my favorite. I don’t need other sounds like frogs croaking or locusts buzzing because let’s be honest, it’s a little hard to fall asleep to that stuff. This app offers what a night’s sleep needs. I appreciate how simple it is, and I also like that the ads aren’t obnoxious and pop up when you’re just trying to use the app.

One small gripe I have is that the brown noise may not do perfect loops, which seem to cause “glitchy” sounds. I’m sure it could be easily fixed, and I hope it does.
Adding a timer would also be handy.

Thank you for this app.

Developer Response ,

We are glad you like our app and are looking into what could be causing these issues on your device!

Soundly Sleeping produces its sound by generating a random pattern according to the sound profile on the fly. As such, it is not a looping issue, but can have to do with the overall process load of the phone.

If you are experiencing sound glitches, please try the following:

* Close other apps running in the background. These might be straining the phones processor to where Soundly Sleeping can't keep up with the generation of the noise.
* Have Soundly Sleeping running in the foreground by turning it on and then locking your screen.
* Put your phone on a charger to ensure it does not go into a low-power mode.

If all else fails, you can try to restart the device. This will stop any competition between Soundly Sleeping and other apps that may be consuming large amounts of background processing power.

We are happy to continue helping you troubleshoot this issue and you can reach us directly at

Thank you!

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!

Best App for Brown Noise

Hands down, best app for brown noise. I have had this app for years and rely on it every single night to sleep. I wouldn’t know what to do without it! Works reliably every single time. I have never had issues. Has been stable across multiple app updates and over multiple phone upgrades year-after-year. Wouldn’t use anything else! A huge thank you to the developers.
