CircadiaOS

Adaptive sleep optimization without expensive mattress pods

CircadiaOS is software-only sleep optimization. No mattress pod, proprietary sensor, or new hardware required. It connects wearables like Garmin, Apple Watch, Oura, and Whoop with smart thermostats like Nest, Ecobee, and Honeywell to deliver personalized sleep science using devices people already own.

Each night, CircadiaOS reads your biometrics, builds a personalized overnight temperature schedule, and automatically runs your thermostat through it. Most sleep apps tell you that you slept badly. CircadiaOS actually does something about it.

Software-only. Adaptive. $19.99/month. Available on iOS.
