Intermittent Fasting Tracker & Timer
Set your own schedule and run a simple browser timer; this tool does not prescribe a plan or assess health.
A QUICK WALKTHROUGH
How to use this tool
- Enter fasting and eating durations.
- Start, pause or reset the local timer.
- Use the phase and remaining-time display as a reminder.
User-configured only
Durations are entered by you. The tool does not recommend fasting, assess suitability, or make weight, nutrition or medical claims.
Local timer
The timer runs in this browser and is not a health record. Keep your own safety and care decisions outside this tool. The countdown advances on browser timer ticks; background throttling or a closed page can interrupt it. It is not a precise elapsed-time measurement.
