Meridian is the fasting app for people who are tired of fasting apps. No 15-screen onboarding quiz. No AI coach upselling you a meal plan. No gamification badges. No paywall on the timer. Just a clean, powerful tool that respects your intelligence and your time. START IN SECONDS One tap to start. One tap to stop. Meridian tracks your fasting window, shows what's happening in your body at each metabolic phase, and stays out of your way. Every schedule built in — 14:10, 16:8, 18:6, 20:4, OMAD, or set your own custom window. REAL SCIENCE, NOT SLOGANS Each body phase is grounded in peer-reviewed metabolic research. Know when glycogen depletes. Know when ketosis begins. Know when autophagy ramps up. Meridian tells you what's actually happening — with citations, not marketing copy. YOUR DATA STAYS ON YOUR DEVICE No account required. No cloud sync you didn't ask for. No analytics tracking your behavior. All data lives on your iPhone and stays there. Optional Apple Health integration reads and writes only with your explicit permission. DESIGNED WITH INTENTION Every screen earns its place.
