About 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.
