About Circadian AI - Biohack Coach
Circadian AI is the science-based wellness protocol tracker and AI coach designed around circadian biology, evidence-backed morning routines, sleep optimization, and daily habit stacking. Built for people who take their health seriously. THE PROTOCOLS The research is clear. What you do - and when you do it - determines your energy, cognition, sleep quality, and long-term health. Circadian AI puts the most effective science-backed protocols into a single, structured daily system. Morning sunlight exposure. Cortisol pulse timing. Cold exposure. Physiological sigh breathwork. NSDR (Non-Sleep Deep Rest). Time-restricted eating and fasting windows. Heat exposure. Exercise timing. Sleep anchoring and wind-down protocols. Each one is grounded in peer-reviewed research on circadian biology and neuroscience. Each one is trackable, stackable, and optimized for your schedule. YOUR AI COACH Most health apps give you data. Circadian AI tells you what to do with it. After tracking your protocols, your built-in AI coach analyzes your compliance patterns, identifies what's working, and surfaces personalized recommendations based on your actual behavior — not generic advice. If your sleep quality drops when you skip your evening wind-down, Circadian AI sees it. If your energy scores improve on days you hit your morning light window, Circadian AI tells you. WHAT YOU GET Track every major wellness protocol in one place — morning light, NSDR, cold exposure, breathwork, fasting, sleep anchoring, and more AI coaching overview that analyzes your data and tells you what's actually moving the needle Circadian-aware scheduling that times your protocols to your biology, not just your calendar Daily compliance scoring so you know exactly where you stand Sleep optimization tracking linked to your daytime protocol behavior Clean, distraction-free interface built for daily use — not for screenshots Your protocols. Your data. Your AI coach. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
