Fasting Timer

What is Fasting Timer?

Fasting Timer helps you track intermittent fasting windows with countdown timers for popular protocols like 16:8, 18:6, and 20:4. See elapsed and remaining time at a glance, and get notified when your fasting window ends.

How to use

1. Choose your fasting protocol (16:8, 18:6, 20:4, or custom hours) and tap start when you begin your fast.
2. Watch the countdown timer and progress ring show how far along you are in your fasting window.
3. End your fast manually or let the timer complete, then review your fasting history.

Result

Start a 16:8 fast at 8pm after dinner. The timer counts down 16 hours, showing you can eat again at 12pm noon the next day.
