Sleep monitoring with hospital-grade technology
Owlet Dream Sock is a soft smart sock, which is securely worn on the left or right ankle of the baby. Dream Sock accurately measures your baby's heart rate, oxygen level and sleep rhythm.
The smart sock utilizes the same pulse oximetry technology used in hospitals. This ensures accuracy of measurements with a margin of error of +/- 3%. The information is relayed in real time to the Owlet Dream app and the device's access point, both of which notify parents if the baby's health readings change outside the presets and the baby needs your attention.

Dream Sock started with a shared idea of the father-of-four
Owlet is an American brand founded by fathers of four, with the goal of helping babies and parents with technological solutions that create peace of mind and increase parental security when facing a new and exciting stage of life.
The first product developed by Owlet in 2015 was the Smart Sock, which is a smart sock that measures a child's heart rate and oxygen levels. It allows parents to monitor their child's health very closely.
Launched in 2018 Owlet Cam which, together with Smart Socks, allows parents to hear and see from their own mobile phone that in addition to health readings, that the child is doing well.
In 2024, Owlet will launch the first medically certified stash alarm designed to provide parents with reliable readings and signals of a baby's abnormal heart rate or low oxygen levels.
