How is Dream Sock different than BabySat?

June 16, 2023

We recently announced clearance from the U.S. Food and Drug Administration (“FDA”) of BabySat™, Owlet’s first medical pulse-oximetry device featuring its advanced, wire-free sock design. As a leader in infant health and monitoring, the addition of BabySat combines our consumer-first expertise with hospital-grade monitoring accuracy.

We know one of the most important questions you may have is, “What is the difference between BabySat and Dream Sock?” The main difference to keep in mind is that BabySat is a prescription only, medical device intended for babies that a healthcare provider determines could benefit from additional monitoring at-home under the supervision of a physician. Dream Sock is our award-winning consumer product, intended to assist caregivers in tracking their child’s well-being by monitoring sleep patterns, quality and duration of sleep. We also submitted Owlet’s Health Notifications software as a medical device technology for regulatory clearance by the FDA (see announcement here), and we are hopeful that this software will be available as a medical device function for our Dream Sock product line in the future. These distinct product lines all contribute to Owlet’s mission to bring our innovative technologies to help every parent provide at-home care.
