About this app
Free fasting tracker and fasting timer for intermittent fasting, OMAD, and extended water fasts. No ads, no account needed.
Fasting Center is a fasting app built around your numbers, not generic guesses. Start a fast, follow 17 fasting stages on a live ring, and see weight, fat loss, and energy use projected from your own body stats, then measured against what actually happened.
FASTING TIMER AND TRACKER
- Fasting timer with stage markers: fat burning, ketosis, autophagy, and more
- Any schedule: 16:8, 18:6, 20:4, OMAD, multi-day extended fasting, or open-ended
- Ongoing fast notification and home screen widget
- Edit start and end times when life happens
- Projected vs measured weight loss, side by side
TWO FASTING CALCULATORS
- Extended fasting calculator: total weight change, fat, water, glycogen, and protein loss day by day
- Intermittent fasting calculator: daily calorie deficit and expected weight change for your eating window
- Personalized from your sex, age, height, weight, body fat, and activity
MEASURE YOUR PROGRESS
- Log weight, body fat, waist, ketones, glucose, and blood pressure
- Rate energy, hunger, motivation, and stress during a fast
- Health Connect sync: weight and body fat flow in automatically
- Charts over 24h, 7 days, 30 days, 90 days, and a year
- Import your fasting history from Zero and Easy Fast
YOUR DATA, YOURS
- Free fasting tracker, no ads, no subscription
- Works fully as a guest; optional sign-in with Google for cloud backup and sync across devices

Whether you are planning your first water fast, running OMAD, or fine-tuning an intermittent fasting routine you have kept for years, Fasting Center shows you what to expect and what actually happened.
Fasting Center is a planning and estimation tool and does not provide medical advice. Consult a healthcare provider before starting an extended fast, especially if you have any underlying health conditions.
