circady — Your Personal Longevity Protocol Longevity is not one habit. It is the science of keeping every system in your body performing at its best — sleep, movement, nutrition, mindfulness, social connection, and the molecules that support them all. circady tracks all six domains in one place, shows you where you stand right now, and tells you exactly when each routine is ready to be repeated. No questionnaire to fill out. HOW IT WORKS Every routine has a personal recovery window. After you log it, circady tracks the cycle: • Recovering — your body is still processing the last session • Ready — the optimal window to repeat • Needs attention — overdue; this domain is falling behind A Longevity Index score (0–100) summarizes your overall protocol coverage. The higher the score, the more domains you are actively maintaining within their ideal windows. This is supercompensation: come back when you are stronger, not on a fixed calendar date. BUILD YOUR PROTOCOL Start from expert blueprints or build from scratch: • Protocols distilled from leading longevity researchers and evidence-based guidelines • New frameworks added regularly via server-side updates — no app update needed • Fully customizable: rename, adjust recovery windows, set duration, and link to HealthKit • Up to 300 active routines across all domains SIX LONGEVITY DOMAINS • Movement — strength, HIIT, Zone 2 cardio, flexibility • Mental — meditation, journaling, breathwork, learning • Sleep — sleep schedule, no-screen wind-down, naps • Social — quality time, community, nature • Nutrition — fasting, meal timing, specific diets • Molecules — supplements, vitamins, peptides KEY FEATURES • Longevity Index — a single score (0–100) for your overall protocol health • Category tiles — per-category scores with Excellent / Very Good / Good / Fair / Needs Work labels • Daily Coach — surfaces the weakest domain each day with a targeted action tip • Streak tracking — a visual that grows through levels at 7, 14, and 21 consecutive optimal days • Timeline calendar view — see your full history at a glance • HealthKit integration — auto-complete routines from Workouts, sleep data, and more; write back to Health • Apple Watch companion — log and view your protocol from your wrist • iCloud sync — your protocol stays in sync across all your devices • Sign in with Apple — private, fast, secure account • 8 visual themes — personalize the look of your protocol tracker • Export — download your full history as CSV PRIVACY • Sign in with Apple (no password, no third-party login) • All data stored in your private iCloud container • Analytics are minimal and can be disabled in Settings • No advertising, no data selling DISCLAIMER circady is for general informational and educational purposes only.
