Step By Step Guide Download Happiest Baby, makers of SNOO

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!


PROGRAM SNOOBIE ROUTINES

SNOObie is our all-in-one white noise machine and nightlight system! This portable bedtime buddy features customizable nightlight colors and special soothing sounds that can be controlled

with the App. To program SNOObie routines that signal when it’s time to sleep or when it’s okay to wake, just pick your preferred light color, sound, time, and day(s) of the week. Once you save the routine, set it by tapping your device to SNOObie, and your routine will be ready to play at the scheduled day and time!


A Wi-Fi® connection is required to connect the App to your Happiest Baby products. An NFC-enabled device is required to connect the App to SNOObie. For more info or if you have questions, visit HappiestBaby.com!

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).

AI "assistant" frequently makes mistakes such as using data from the wrong day, stating the wrong time of day, and missing days worth of entries. It is completely unreliable. What is the point? I will be using another app to track daily baby data as this is useless bloat to justify an expensive monthly fee. Edit: The paid app is not just for secondhand users. If you purchase you only get a 9 month free trial. God forbid you have more than one kid and want to use the app for your other kids too.

We’re sorry to hear this. This feature is designed to make things easier for a more seamless experience and we’d like to troubleshoot at happiestbaby.com/contactus. To clarify, the fee applies to those who use SNOO secondhand and choose to opt in, and all families can use the free version of the App.

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!
