FastGuard: Fasting Coach

FastGuard is a coach for extended fasting. It steps in during Crisis Mode — the moment you're most likely to quit — and helps you get through it. Track your autophagy and ketosis stages as you go.

CRISIS MODE
It's 3am and you want to break the fast. Open Crisis Mode:
- A 3-minute breathing delay before you decide anything
- A look at what you'd give up — the hours and autophagy progress already behind you
- A message from your past self, written right after your last failed fast
- The choice: keep going or stop. Either way, not on impulse.

MADE FOR LONGER FASTS
FastGuard is built for 24-hour fasts and longer. If you're doing 16:8, you probably don't need it yet — this is for when you go further.

7-STAGE FASTING TRACKER
See where you are: digestion, fat burning, ketosis, autophagy, and peak autophagy. Each stage tells you what your body is doing right now.

DANGER ZONE
- Ghrelin wave alerts every 90 minutes, each with a short breathing session
- A checklist to run before the hours you usually struggle
- A craving log — write the craving down instead of acting on it

INSIDE YOUR CELLS
Short, plain explanations of what each fasting stage does inside your body — based on the autophagy research that won the 2016 Nobel Prize in Medicine.

GOOGLE DRIVE BACKUP
Your fasting data backs up to your own Google Drive automatically. Switch phones or reinstall, and your history is still there.

HEALTH NOTICE
FastGuard is not medical advice. Talk to your doctor before doing any fast longer than 24 hours.
