Autophagy is a minimalist fasting timer that tracks your body's metabolic phases in real time — from digestion through glycogen depletion to autophagy and beyond. SCIENCE-BASED FASTING PHASES Follow your progress through 7 distinct metabolic phases, each backed by research: • 0–4h: Digestion — insulin active, nutrient absorption • 4–12h: Glycogen depletion — blood sugar stabilizes, insulin drops • 12–16h: Fat burning — glycogen depleted, switching to fat • 16–24h: Early autophagy — cellular cleansing begins, growth hormone rises • 24–48h: Active autophagy — significant cell cleansing, deep ketosis • 48–72h: Peak autophagy — immune system renewal, IGF-1 drops • 72h+: Deep autophagy — advanced cell regeneration REAL-TIME TIMELINE See exactly where you are in the fasting process. Each phase shows key biological processes, active markers, and how far you've progressed. Completed phases are marked, upcoming ones give you something to work toward. FLEXIBLE START Start fasting now or set a custom time for when your last meal was — the timer adjusts automatically. OPTIONAL GOALS Set a target duration to see your remaining time and track goal completion in your history. FASTING HISTORY & STREAKS Review past fasts with duration, phase reached, and goal status. Track your current and longest streaks to stay motivated. APPLE WATCH A full companion app for your wrist. Track your fast, see your current phase, and stop your timer — all without reaching for your phone. NOTIFICATIONS Choose between no notifications, reduced (start and end only), or all phase transition alerts. Stay informed without being overwhelmed. EXTENDED MODE Continue tracking beyond 72 hours for advanced fasting protocols. PRIVACY FIRST All data stays on your device. No accounts, no cloud sync, no tracking. Autophagy was inspired by Nobel Prize-winning research on cellular self-renewal. The app is designed with a Dieter Rams-inspired aesthetic: minimal, typographic, and functional — so you can focus entirely on your fast.
