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 monitor the things that really matter, when it matters most. Our newest Sock is the third of its kind and smarter than ever.

Worn comfortably around your baby’s foot, the Smart Sock proactively tracks your baby’s heart rate and oxygen level—a key indicator of Baby’s health. If your baby’s readings leave designated “safe” zones, the Base Station will notify you with lights and sounds so you know to check on your baby. Track your baby’s wellness in real-time from anywhere using the Owlet mobile app, and gain valuable insights into the length and quality of your baby’s sleep.

Owlet is intended to provide peace of mind. It is not intended to diagnose, treat, mitigate, cure, or prevent any disease or condition.
