CircadiaOS adjusts your bedroom temperature through the night, automatically. Your body temperature isn't constant while you sleep. It drops as you fall asleep, stays low through your deepest sleep, and rises again before you wake. A thermostat held at one number all night works against that. CircadiaOS builds a temperature curve for your night and drives your smart thermostat to follow it. Connect a wearable and the curve adapts to your own recorded nights instead of a general model. HOW IT WORKS - Connect your thermostat and your wearable - CircadiaOS builds a curve from your profile on night one - As your nights accumulate, the curve shifts to your own data - See exactly which parts come from your sleep and which are still estimates WHAT YOU SEE - Tonight's schedule, phase by phase - Why each setpoint is what it is - Your best and worst nights, side by side, and what differed Requires a compatible smart thermostat. A wearable is optional but unlocks personalization from your own sleep data. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
