Circadian AI Sleep & Rhythm

Circadian AI reads your body clock — not your data. It turns your Apple Health sleep and your local sunrise into a personal circadian phase, then builds one simple daily plan: when to get morning light, cut caffeine, eat, do NSDR, and wind down for sleep. Everything runs 100% on your iPhone. No account. No logging. Works offline — nothing about your health ever leaves your phone. WHY CIRCADIAN AI • On-device engine — private by design, no servers, no sign-up • Personal circadian phase from real sleep + HRV + sunrise data • A clear daily protocol instead of another dashboard of numbers • Built on published circadian-science principles (light, timing, temperature) YOUR DAILY PLAN • Morning light window — when to step outside for the biggest shift • Caffeine cut-off — timed to protect tonight's sleep • Meal & movement timing aligned to your rhythm • NSDR / wind-down prompts to help you downshift in the evening • Chronotype-aware — early bird or night owl, the plan adapts WORKS WITH APPLE HEALTH Connect Sleep and Heart Rate data (optional) and Circadian AI does the rest — reading trends on-device to fine-tune your timing every day. WHO IT'S FOR • Anyone rebuilding a sleep schedule or fixing a late body clock • Shift workers, travelers, and students out of sync • Biohacking, longevity, and morning-routine fans who want signal, not noise PRIVATE BY DESIGN No email. No cloud profile. No tracking. You can use the full plan without handing your data to anyone. MEMBERSHIP Circadian AI is a subscription with a free trial.
