This smart baby monitor helps you know your baby is okay by using clinically-proven technology to track their heart rate and oxygen levels. The Smart Sock sends this information to a base station which is designed to notify you with lights and sounds if something appears to be wrong. Using Owlet's app, you can view real-time wellness data and receive direct notifications on your phone. Parents who use the Owlet Smart Sock report better sleep and less worry. All new moms and dads can use peace of mind and a little extra help with baby while they sleep.
