The Smart Sock Plus fits babies and children, 5lbs to 55lbs or 0 - 5 years. It tracks your baby’s or child’s oxygen level and heart rate. If the readings leave pre-set zones, you'll receive a notification that lets you know your baby or child really needs you. Empowering parents with a better understanding of their child’s needs as they grow.

The award-winning Smart Sock from Owlet 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. The smart sock comfortably wraps around the baby's foot and connects to a base station which then connects to an app on your smartphone to provide you will all the information in an instant. If your baby's readings leave preset safe zones, you'll receive a notification that lets you know your baby really needs you. Over a million parents around the world trust Owlet every night to help them keep their babies safe while they sleep.

Unlike traditional audio and video baby monitors the Owlet Smart Sock is the first ever monitor to track your baby's heart rate and oxygen levels while they sleep using clinically-proven pulse oximetry and sending you notifications straight to your phone.

Be alerted through the base station which notifies you with lights and sound if something appears to be wrong and monitor your baby's readings directly on your phone. Be alerted instantly if oxygen levels drop below the preset threshold. You can also view total hours slept, number of wakings, and sleep quality. Check your baby’s readings in real time & review a detailed 7-day wellness history.

The battery lasts 16 hours. You can get 8 hours battery life in 20 minutes and a full charge in 90 minutes. In addition, you can charge wirelessly by using a convenient drop-and-go on the base station.
