CircadiaOS
Sleep optimization, minus the $3,000 mattress pod
What is CircadiaOS?
CircadiaOS is software-only sleep optimization. No mattress pod, no proprietary sensor, no new hardware. It connects the wearable and smart thermostat you already own, builds a personalized overnight temperature schedule from your biometrics, and runs your thermostat through it automatically every night. Most premium sleep tech in this category has been hardware-first: thousand-dollar mattress pods, dedicated sensors, custom firmware. We took the opposite bet.
From the website
CircadiaOS is an iOS app that connects sleep trackers (Oura, Whoop, Apple Watch, Garmin, Fitbit) to smart thermostats and automatically adjusts your bedroom to a personalized nightly temperature curve to improve sleep quality.
