See how it worksTHE APP
Fasting is hard. Fasting Tracker keeps it simple, and stays on your side the whole way.
Start with 13:11, 14:10, 16:8 or 18:6. With Pro, go further: 20:4, one meal a day, 24 or 36 hours, or your own plan from 12 to 72 hours.
The ring shows how far you have come and which of 8 stages you may have reached, from blood sugar to ketosis and autophagy, with a timeline that explains each one.
Every completed fast grows your streak and moves you toward 25 badges. Reminders let you know when your goal is near, at each new stage and before your eating window closes.
YOUR PROGRESS
Look back on every fast with your stats, a 7-day chart and a month calendar. Fasting Tracker Pro adds a 30-day trend.

ALWAYS WITH YOU
Follow your fast on Apple Watch, the Home Screen and the Lock Screen, and start a fast right from a widget.
Your fast stays on the Lock Screen and in the Dynamic Island, and you can complete it from there.
Start a fast, end it, or ask how long you have been fasting.
Your fasts, settings and badges back up to your private iCloud and stay in sync. No account needed.
Fasting Tracker is designed for general wellness and is not a medical device. Fasting is not right for everyone. If you are pregnant, diabetic, have a history of eating disorders or take medication, talk to your doctor first, and before any extended fast.
COMING SOON
Fasting Tracker is getting ready for the App Store, for iPhone and Apple Watch.
