Yawn vs CircadiaOS

You know that feeling — waking up and actually feeling rested. Clear-headed. Like yourself again. Yawn helps you get there. Most sleep advice stops at "get 8 hours." Your body never read that memo. Yawn learns what your body actually needs from your own sleep history, then shows you the one number that matters: your sleep debt — how much rest you owe yourself, and exactly how to pay it back. THE NUMBERS THAT MATTER • Sleep score — a clear rating every morning, so you know what kind of day you're walking into • Sleep debt — the rest you owe your body, tracked night over night • Your sleep need — how much sleep you personally need, learned from your history, not a generic 8 hours • Regularity — how steady your sleep and wake times really are • Energy curve — your predicted highs and lulls through the day, so you can plan around them A PLAN, NOT A LECTURE • Ideal schedule — your personal bedtime, wind-down window, and morning-light window • Smart alarm — wakes you at the right time and rings through silent mode and Focus • Gentle reminders — wind-down, last coffee, morning light, bedtime, all timed to you • Wind-down tools — guided breathing and calming sounds for the nights sleep won't come MEET YOUR SLEEP COACH Ask it anything. Yawn's coach knows your real numbers, your goals, and what's keeping you up — and talks you through it like someone who's actually read your chart, not a chatbot reading a script. SCAN YOUR ROOM Point your camera at your bedroom and Yawn flags what might be quietly costing you sleep — light, heat, clutter — with simple fixes. The photo is analyzed and never stored. HOW IT WORKS Yawn reads your sleep from Apple Health — no wearable required; it can even estimate your nights from your phone alone. A short quiz personalizes everything to your goals. From there it's simple: sleep, check your score, pay down your debt. — Subscription details: Yawn requires a subscription for full access. Payment is charged to your Apple ID at confirmation.

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/
