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!

Prior to the paid subscription the app and the snoo itself was great. I loved being able to look at our first's log and comparing to our most recent addition. Since the new app and the additional paid subscription they now offer the app is the most simple thing now. Thus making the app absolutely useless. They've taken access to the old logs away as well as the current log. Trying to make the most profit they can from sleep deprived parents. Bring the old app back.

We’re sorry to hear you’re disappointed and we’d like to clarify. Everyone who gets SNOO from an authorized partner will have Premium access. The fee applies to secondhand SNOO users who choose to opt in. SNOO was designed to give babies all the sleep and safety benefits, whether families are on Free or Premium, or not using the App at all.

We purchased our SNOO in 2022 and it worked smoothly for our first born using the original app. With the newer app, we are incredibly disappointed. On a number of occasions, the SNOO randomly increases the level completely unnecessarily from baseline to level 1 and then 2 almost immediately. Our baby is sound asleep, making no noise at all, and is then startled awake by the sudden change in motion, completely defeating the point. We need a resolution urgently.

I understand charging for premium features, but that's not what's happening here. They're charging a ton for super basic functionality that should be an open API. You can't even turn the sound off, or reduce the maximum sound. Turning down the volume isn't some new special value or "ongoing innovation" that needs a subscription. As is, this bassinet isn't smart. Go up to cradlewise, or down to one of the ones that just rocks all night, snoo is a useless middle ground.

Anyone can use the free version of the App, which includes the Tracker, Volume settings, Motion Limiter, SNOO Alerts, Baby’s Status, Sleep Tips, & more. SNOO’s sleep & safety benefits work without the use of an App at all and is the only bassinet FDA De Novo authorized for keeping sleeping babies safely on the back (see happiestbaby.com/fda).
