You don't need 200 sounds to choose from! You just need the one that actually puts your baby to sleep (and doesn't annoy you.)

Via physics and musical science we have created a few sound patterns that work like magic and moms can actually enjoy.

And you can even track your baby's sleep!

Also includes a curated compilation of lullabies and classical music to help your baby gradually become calm and transition into sleep.


We are young parents who developed Sound Sleeper to help us stay sane when our first child was born, and are still using it for our family. We invite you to download Sound Sleeper for FREE, and treat the whole family to a good night’s sleep!

8 years of Sound Sleeper and counting

I’ve used sound sleeper with all 3 of my kids over the last 8 years. Mountain River is our favourite. Super responsive customer support if you need help. A must have for white noise for your kids

Love this app 👌

I still cannot believe this worked!!
I went threw 5 noises, then I found 1 my son loves and enjoys, which is cars!! He fell asleep to the sound of a vehicle within 4 minutes 🤗
Love it

Great app for babies!

As a first time Mum this app has really helped our household put baby to sleep and also disguise noises that could wake her. The only downside is the maximum 30min of free continuous play... would be great if it was 1hr or if payment was a one off. I highly recommend the Mountain River!!
