About Meridian: Circadian Body Clock
Your body has a natural rhythm. Meridian shows it to you. The 2,000-year-old circadian clock from the Huangdi Neijing, on your phone. One-time purchase. No subscription. No account. No cloud. Meridian divides your day into twelve two-hour "hours" — each governed by a different organ system, each with clear "good for" and "avoid" guidance. It's the ancient precursor to modern circadian science, turned into a simple daily tool that keeps you in tune with your own biology. WHY MERIDIAN • Know your natural schedule — Twelve two-hour windows tell you the best time to sleep, focus, eat, exercise and wind down. Stop guessing; your body already has a plan. • Voice reminders that teach — At each hour, Meridian speaks the guidance aloud: what your body is best at, what to avoid. It repeats the rhythm gently until you know it by heart — not nagging, but teaching. • Check-ins & rhythm tracking — Log your day hour by hour and watch your 7 / 14 / 30-day rhythm on a simple dashboard. • Works with your schedule — A time-offset slides the whole clock to match your real day. Night shift? Late chronotype? Shift the hours to fit you, not a one-size-fits-all 9-to-5. • Share your schedule — Generate a beautiful personalized schedule poster and share it in one tap. PRIVATE BY DESIGN No account. No cloud sync. No tracking. No analytics. No ads. Your plans and check-ins never leave your phone. ONE-TIME PURCHASE Pay once, own it forever. No subscription, no in-app purchases, no hidden fees. No "free trial" that quietly becomes a yearly charge. One price, yours forever. DISCLAIMER Meridian provides general wellness guidance based on traditional Chinese medicine. It is not medical advice and is not intended to diagnose, treat, cure, or prevent any condition.
