Why Should I Choose Owlet Smart Sock 3 - Baby Heart Rate & Oxygen Level Monitor?

Owlet Smart Sock 3 - Baby Heart Rate & Oxygen Level Monitor is the third generation of the Smart Sock. The Smart Sock is the first baby monitor that tracks your baby's oxygen level and heart rate - the best indication of baby's health - while they Sleep.

Safe Zones

What's more, this Baby Monitor indicates when your baby's readings leave the preset "safe" zones, by sending you a notification that lets you know when baby really needs you. Then, you can use the sleep history feature to see how long and how well your little one slept. This allows you to use this data to create new routines as baby grows. Now you can feel more confidence, more freedom, and more peace of mind.

Smart Sock Communication

Plus, the Smart Sock communicates with the Base Station even in the event of WiFi disruption, and will notify you with lights and sounds if your baby's heart rate or oxygen drop below the preset levels.
