Free fasting tracker and timer for intermittent fasting, OMAD, and extended water fasts. No ads, no account needed.
Fasting Center is 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.
TRACK YOUR FAST
- Timer with stage markers: fat burning, ketosis, autophagy, and more

- Live Activity and Dynamic Island on iPhone, home screen widgets
- Edit start and end times when life happens
- Projected vs measured weight loss, side by side
TWO CALCULATORS
- Extended fast: total weight change, fat, water, glycogen, and protein loss day by day
- Intermittent fasting: daily calorie deficit and expected weight change for your 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
- Apple Health sync: weight and body fat flow in automatically
- Charts over 24h, 7 days, 30 days, 90 days, and a year
- Import your history from Zero and Easy Fast
YOUR DATA, YOURS

Whether you are planning your first extended fast or fine-tuning a routine you have run 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.
