About this app

Parenting is hard. Getting sleep + peace of mind shouldn’t be! Maximize your Happiest Baby devices’ ZZZs-boosting benefits—plus, get expert tips, track activities & more!

The Happiest Baby App is your all-in-one parenting companion. It connects seamlessly with your Happiest Baby devices, including SNOO Smart Sleeper—the world’s first FDA De Novo authorized infant sleep system—and SNOObie Smart Soother—our all-in-one sound machine, nightlight, and sleep trainer, while offering additional features like a free baby tracker and the Timeline, packed with personalized parenting advice.


CUSTOMIZE YOUR SNOO EXPERIENCE

Created by Dr. Harvey Karp, renowned pediatrician and sleep expert, SNOO intelligently responds to your baby’s needs with womb-like soothing to help the whole family get 1-2+ hours more sleep a night. The Happiest Baby App lets caregivers personalize their baby’s sleep journey with advanced SNOO settings, including:

* Log: Track every SNOOze automatically, see sleep-wake patterns at a glance, and keep tabs on sleep successes!

* Alerts: Get notified if your baby needs more than SNOO's soothing (due to hunger or discomfort).

* Remote Control: Quickly respond to your baby's unique needs by adjusting SNOO’s levels up and down.

* Adapt: Pick the best motion and white noise settings for your baby—boost the level of rhythmic sensation to get through sleep disruptions, adjust sensitivity for the just-right response, and more!

* Easy Weaning: Special setting helps babies learn to sleep without motion, to prepare for the transition to the crib.


EASILY TRACK BABY’S ACTIVITIES

Record sleep (in and out of SNOO), feeds, diaper changes, and pumping all in one place so you get a full picture of your baby’s routines!


GET DR. KARP’S ADVICE…AT YOUR FINGERTIPS

Like a pediatrician in your pocket, more than 1,000 articles and expert tips are available in the Timeline to answer your questions and guide you through every little milestone of babyhood...and beyond!

I don't have a previous version to compare to, but I do really love this app for use of the Snoo and for tracking breastfeeding, pumping, diapers, etc. My main gripe is that I can't adjust the Snoo sleep entries (delete or comment or anything). I would like to be able to delete entries where he didn't sleep or comment about his quality, etc. Other tracking categories allow notes which is super nice!

terrible. not helpful. time consuming. I was trying to get help in the app and you only get 3 free messages a day! and 10 total! a limit to the help I get! yeah no, I'm deleting it. not helpful, doesn't even work! if I'm using my phone to use it I shouldn't have to create an account! this is stupid and aggravating! I'm not even able to sync the snoo to the app. and needing to hook up to my Wi-Fi is another weird thing!

You buy a $1500 bassinet, yet you still have to pay a subscription for the features of the app to work. Edit: Snoo claims that anyone who buys from them gets the premium subscription free. If this is true, why did it turn off on my account in the first place? Original account from day one and when my third kid came around, all the features went away. I can't even change the responsiveness without paying a subscription now. Can't find where to activate complementary premium anywhere!

We understand that as a premium product SNOO carries a higher price tag, and we’d like to clarify. Anyone who rents or buys SNOO from an authorized retailer receives complimentary Premium access. The monthly fee applies to secondhand SNOO users who choose to opt in. Everyone has access to the free version which includes features for daily SNOO use.
