The Owlet Smart Sock comfortably wraps around your baby’s foot to track heart rate, oxygen levels and sleep using clinically-proven pulse oximetry. The base station glows green to let you know everything is okay but notifies with lights and sounds if heart rate or oxygen levels leave preset zones. Parents can see live readings using Owlet’s app but can also use trended sleep data and historical heart and oxygen information using the Connected Care app to improve their baby’s overall wellness.

    What’s the difference between Smart Sock (SS) 2 and Smart Sock (SS) 3?
    SS3 has been completely redesigned to accommodate more babies, from 5 to 30 pounds, and continues to track Baby’s heart rate and oxygen through gentle motion. Quick, wireless charging delivers a fully charged SS in just 90 minutes, with a battery life of 16 hours. SS 3 has an improved Bluetooth range and allows parents to snooze Base Station notifications for more controlled monitoring.

    Will the Smart Sock (SS) still work if my Wifi goes out?
    Yes! The SS communicates with the Base Station even in the event of Wi-Fi disruption, and will notify you with lights and sounds if your baby’s heart rate or oxygen drop below the preset levels. The Base Station is your primary notification device.

    Can my baby wear footie pajamas or a swaddle with the Smart Sock (SS)?
    The low-profile design of the SS was designed to be worn under footie pajamas, a sleep sack or a swaddle.

    Does the Smart Sock (SS) work for twins?
    Yes, the SS works for twins and each baby needs their own SS and Base Station unit. Parents can add both devices to the same Owlet app to view live readings of both babies in the same app.

    Does the Smart Sock (SS) work through motion?
    The SS was designed to track during gentle motion and continues to track your baby’s heart rate and oxygen level through the gentle movement of sleep.

    Is the technology used safe for my baby?
    Yes! The SS uses safe and proven pulse-oximetry technology to gather your baby’s heart rate and oxygen levels. Pulse-oximetry is the same technology used at the doctor’s office when they place the little red clip on your finger.
