CircadiaOS — Software‑Only Sleep Optimization

Sleep is one of the most important factors in health and performance, yet most solutions on the market either stop at tracking or require expensive hardware. CircadiaOS takes a different approach. It is a software‑only sleep optimization system that works with devices you already own — no mattress pods, no proprietary sensors, and no new hardware to buy. By bridging two rapidly growing markets — wearables and smart thermostats — CircadiaOS delivers personalized sleep science without the hardware markup.

How It Works

Each night, CircadiaOS reads biometric data from your wearable device — whether it’s a Garmin, Apple Watch, Oura, Whoop, or similar tracker. Using this information, it builds a personalized overnight temperature schedule and automatically runs your smart thermostat (Nest, Ecobee, Honeywell, and others) through it. The methodology is grounded in peer‑reviewed sleep science: a 14‑night baseline calibration followed by one‑variable‑at‑a‑time hypothesis testing, all tailored to your personal biology.

Most sleep apps simply tell you that you slept poorly. CircadiaOS goes further: it intervenes. By adjusting your sleep environment in real time, it actively helps you sleep better instead of just reporting the problem.

Key Features

• Personalized Sleep Optimization — Uses wearable data to improve sleep quality.

• Smart Thermostat Control — Automatically adjusts your thermostat throughout the night.

• No New Hardware Required — Works with devices you already own.

• Science‑Based — Built on established sleep science principles.

• Automated Operation — Set it up once, and it runs every night without manual input.

• Personalized Temperature Schedules — Tailored to your body’s unique needs.

• Intervention, Not Just Tracking — Actively improves sleep instead of just monitoring.

• Adaptive Learning — Gets smarter over time by testing different schedules based on your biology.

Why CircadiaOS Stands Out

Unlike hardware‑based solutions that require costly purchases, CircadiaOS leverages the ecosystem of devices already in millions of homes. This makes it accessible, affordable, and scalable. At just $19.99/month, it provides advanced sleep optimization without the barrier of expensive equipment.

Its adaptive learning system ensures that the longer you use it, the better it gets. By continuously testing and refining temperature schedules, CircadiaOS evolves alongside your biology, delivering increasingly effective results.

Final Thoughts

CircadiaOS is more than another sleep app. It’s a software‑only, adaptive intervention system that transforms how you sleep by combining wearable biometrics with smart thermostat control. No buttons to tap, no schedules to manage, nothing to think about — just better sleep, every night.

Available now on iOS, CircadiaOS is the future of sleep optimization: simple, science‑based, and hardware‑free.
