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.

The Smart Sock is effective during gentle motion, including with use of products like a motion bassinet. Designed for use anywhere in your home while your baby sleeps, the Smart Sock also includes one-handed, quick wireless charging to deliver a completely charged Sock in just 90 minutes. And when you’re short on time, just drop the Sock on the Base Station and get an eight hour charge in less than 20 minutes. For new parents, expecting parents, or parents who have seen it all, the Smart Sock delivers the right information at the right time to help you keep your baby safe so you can enjoy more of the journey.
