Let's keep every baby safe.

Parents around the world trust Owlet every night to help them keep their babies safe while they sleep. Our award-winning Smart Sock goes beyond the capabilities of any other baby monitor to tell you the things that really matter, when it really matters.

The Smart Sock is the first baby monitor to track your baby’s oxygen level and heart rate—the best indication of baby’s health—while they sleep. If your baby’s readings leave preset “safe” zones, you'll receive a notification that lets you know your baby really needs you. Now you can feel more confidence, more freedom, and more peace of mind knowing that Owlet is here to help you keep your baby safe.

Our all-new Smart Sock is the third of its kind and it's smarter than ever.
