CircadiaOS is a software-only sleep optimization app for people who already own a wearableand a smart thermostat. It connects the two devices, builds a personalized overnight temperatureschedule using biometric data from the wearable, and runs the thermostat through that scheduleautomatically every night.What CircadiaOS does● Connects wearables and smart thermostats○ Integrates with Garmin, Apple Watch, Ōura, Whoop wearables and 17 smartthermostat brands.○ Users link their existing devices once and the system handles everything fromthere.● Builds a personalized overnight temperature schedule○ Each night, CircadiaOS reads biometric data from the wearable (HRV, heart rate,sleep staging, skin temperature) and constructs a temperature curve tailored to theuser&amp;#39;s biology.○ The schedule flexes with sleep duration so it works whether the user sleeps sixhours or nine.Adaptive Methodology and Machine LearningThe CircadiaOS system functions as a sequential testing manager running a controlled, per-usertest on your own biology.1. Baseline Calibration: The first 14 nights establish a personal sleep baseline and howyour body responds to temperature changes.2. Controlled Hypothesis Testing: Starting on night 15, the system isolates and adjusts onetemperature variable at a time. This ensures that any measured outcome is causallyattributed to that change.3. Personalized ML Model: After approximately 30 labeled sessions are complete, apersonalized machine learning model proposes optimized temperature setpoints.However, the ongoing testing loop remains the ultimate judge.4. Optimization Score: An internal Sleep Quality Index (SQI) is computed each morningfrom inputs like HRV, sleep efficiency, total sleep time, and REM duration. This score isused to evaluate if the previous night&amp;#39;s schedule produced better sleep.5. Core Defensibility: The true advantage of this system is the clean, longitudinally-labeledsleep data generated under controlled conditions for every user.● Runs the thermostat automatically○ Once a schedule is set, CircadiaOS issues commands to the thermostat throughthe night without user input.○ Nothing to tap, no schedule to manage, no daily decisions to make.● Operates within a research-backed safety range○ All schedules stay within a 63 to 70°F operating range based on published sleepscience.○ No schedule can push outside that range regardless of personalization.Why people use CircadiaOS● To make use of biometric data their wearable already collects, typically unutilized bymost users.● To replace the manual, uninformed overnight thermostat setting most homes default to.● To improve sleep quality through a system grounded in peer-reviewed science rather thanvague wellness claims.● To set up a sleep system once and have it run automatically every night.CircadiaOS fits into existing devices● The wearable is the input. CircadiaOS reads biometric data each morning to evaluate theprevious night.● The smart thermostat is the output. CircadiaOS issues a personalized schedule beforesleep and runs it automatically.● The app sits between them as the analysis and scheduling layer. Users never manuallyadjust either device.Built for● People who already own a wearable and a smart thermostat● Users who want measurable improvements to sleep without buying additional hardware● Perimenopausal and menopausal women, who experience temperature-related sleepdisruption at higher rates and benefit most from adaptive overnight scheduling● Elite athletes who prioritize physiological recovery as a competitive edge● Dedicated fitness enthusiasts who view adaptive temperature as the ultimate recoverytool● Corporate executives navigating demanding schedules who require optimized sleep forpeak cognitive output● People who track their sleep and want a product that acts on the data rather than justreporting itAvailable on iOS. $19.99/month.
