Fasting Tracker
Monitor intermittent and extended fasting with precision—track eating windows, metabolic phases, and autophagy milestones in real-time.
What it does
- Fast Timer: Start a fast and get real-time elapsed tracking with countdown to key metabolic milestones
- Eating Window Tracking: Log when you break your fast and automatically calculate your eating window duration
- Metabolic Milestones: Receive alerts at ketosis (12h), fat adaptation (16h), autophagy (24h), and deeper cellular renewal thresholds
- Smart History: Review past fasts with duration, eating windows, and consistency metrics
Usage
Start Fast
"Start a fast" or "begin fasting"
- Logs the fast start time
- Displays current time and target milestones
- Sets background tracking (runs even when you close the app)
Break Fast
"Break my fast" or "I'm eating now"
- Records the end time
- Calculates total fast duration
- Shows eating window recommendation and next fast opportunity
Check Timer
"How long have I been fasting?" or "fasting status"
- Displays elapsed time
- Shows next metabolic milestone and time remaining
- Displays current autophagy phase if applicable
Fast History
"My fasting stats" or "fasting progress"
- Lists recent fasts with duration
- Shows weekly consistency
- Displays longest streak and average fast length
Set Schedule
"Schedule my fasts" or "fasting protocol"
- Configure preferred fasting protocol (16:8, OMAD, etc.)
- Set daily reminders for fast start/end times
- Customize notifications for key milestones
Metabolic Timeline
| Duration | Milestone | Status |
|---|---|---|
| 12 hours | Ketosis Begins | Glycogen depletes; body shifts to fat burning |
| 16 hours | Fat Adaptation | Insulin drops further; metabolic efficiency improves |
| 24 hours | Autophagy Activation | Cellular cleanup intensifies; damaged proteins recycled |
| 36 hours | Deep Autophagy | Mitochondrial renewal accelerates; immune reset begins |
| 48 hours | Cellular Regeneration | Growth hormone peaks; stem cell activation (rodent studies) |
| 72+ hours | Extended Benefits | Sustained autophagy; metabolic recalibration; requires medical oversight |
Fasting Protocols
- 16:8 Intermittent: 16-hour fast, 8-hour eating window (most beginner-friendly)
- 18:6 Intermediate: 18-hour fast, 6-hour eating window (moderate difficulty)
- 20:4 Warrior: 20-hour fast, 4-hour eating window (lean gains focus)
- OMAD (One Meal A Day): 23-hour fast, 1-hour eating window (advanced)
- 24-Hour Fast: Full day fast (once or twice weekly)
- Extended Fast: 36–72+ hours (consult healthcare provider; requires electrolyte management)
Tips
- Electrolytes Matter: Extended fasts deplete sodium, potassium, and magnesium. Supplement or drink bone broth to prevent cramping and fatigue.
- Hydration is Essential: Water, herbal tea, black coffee, and green tea are fasting-friendly; any calorie breaks the fast.
- Listen to Your Body: Fatigue, dizziness, or intense hunger warrants eating—fasting should enhance, not impair, daily function.
- Consistency Beats Intensity: A sustainable 16:8 protocol done for months outpaces sporadic 72-hour fasts; build the habit first.
- All data stays local on your machine: Your fasting logs, schedules, and metrics never leave your device—complete privacy, no cloud sync required.
