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.
