BabySat is not the same product as Smart Sock, as BabySat is a new FDA-cleared medical device to be prescribed by healthcare providers in the US and Smart Sock is a consumer product offered only outside of the US and Canada. BabySat provides real-time alerts if pulse rate or oxygen saturation level falls outside a prescribed zone. Unlike Smart Sock, BabySat has adjusted reading levels and is a prescription only device that should be used in partnership with your healthcare provider. Owlet does not anticipate marketing Smart Sock within the US or Canada in the future. Dream Sock is the first and only non-prescription baby monitor with FDA-cleared Live Health Readings and Health Notifications for healthy babies between 1 to 18 months. Available to current and new Dream Sock users.
