Worry less, sleep better! The Owlet Smart Sock 3 is the first ever baby monitor to track your baby’s oxygen levels and heart rate – the best indication of baby’s health – while they sleep. Ideal for babies from birth to 18 months, the fabric socks fit 5lbs to 30lbs for both left and right feet.

• Innovative design, the Smart Sock is the smartest baby monitor, using pulse-oximetry technology proven to be both safe and accurate.
• Tested pre-set zones, if your baby dips out of these zones you will be notified through the base station and mobile app.
• Free mobile app, accessible on any device. Pair this up with your base station, and you can check on your baby’s live readings anywhere with Wi-Fi!
• Use the sleep history feature on the app to see how well your baby slept, and create new routines as your baby grows.
• No messing around with wires, the sensor can be charged wireless via a convenient drop-and-go on the Base Station. The sensor has a 16 hour battery, and a full charge in 90 mins.
