Morph

Morph is the fasting app that grows with you. Most people try fasting alone and quit within two weeks. Morph is different. You get a companion — Mito — who starts as an egg and evolves through five stages as you hit milestones. Your transformation is their transformation. FLIP YOUR METABOLIC SWITCH When you fast, your body shifts from burning sugar to burning stored fat. This is the metabolic switch — and it's where the real benefits begin: mental clarity, stable energy, cellular renewal. Morph shows you exactly when you enter each metabolic zone so you know what's happening inside. FASTING ZONES - Digesting (0-4 hrs) - Transition (4-8 hrs) - Entering Fat Burn (8-12 hrs) - Metabolic Switch (12-16 hrs) - Clarity Zone (16-20 hrs) - Deep Renewal (20-24 hrs) - Autophagy Mode (24+ hrs) 11 SCIENCE-BACKED PROTOCOLS From beginner-friendly 16:8 to extended fasts, plus cycle-synced plans for women and Ramadan mode for spiritual fasting. Start where you're comfortable and build your fasting capacity over time. MITO — YOUR FASTING COMPANION Mito evolves as you progress: Egg → Caterpillar → Cocoon → Butterfly → Spirit Animal Every fast you complete helps them grow. Every streak you maintain unlocks new stages. At 100 fasts, you choose your spirit animal from six archetypes. It's the accountability system that actually works. MITOAI COACH Get your fasting questions answered instantly. MitoAI understands your protocol, your history, and your goals — and gives personalized guidance when you need it. TRACK WHAT MATTERS - Daily check-ins for energy, mood, and mental clarity - Clarity Score to measure cognitive performance over time - Glucose and ketone insights (with Apple Health) - Streak tracking and milestone celebrations LEARN WHILE YOU FAST Unlock science-backed lessons during your fasts. Understand what's happening at each stage — BDNF production, autophagy, ketone metabolism — so you know exactly why you're doing this. BUILT FOR WOMEN Cycle-synced protocols that work with your hormones, not against them. Based on the latest research in female fasting physiology. RAMADAN MODE Auto-calculated suhoor and iftar times, spiritual reflections, and real-time tracking for your 30-day journey. WHY MORPH? - No calorie counting - No food logging - No weight-loss gimmicks Just a proven system for flipping your metabolic switch and a companion who grows with you. Start your free trial today.
