Free fasting timer
MyFastingClock is a free unlimited fasting timer for intermittent and extended fasts.
Track elapsed time, educational metabolic stages, and history. No time caps and no
subscriptions. Not medical advice.
Beside the timer is a Fasting Library of original notes: practice, research limits, and
history. Not medical advice.
Before you use this clock
This is a timer and a teaching map, not a clinician. The ring measures elapsed time. It
cannot see your medicines, your last meal, or whether fasting is safe for you.
Do not start unsupervised if
You are pregnant or breastfeeding, under 18, underweight, or living with an eating
disorder (now or in recovery). Diabetes, kidney disease, and medicines that lower blood
sugar or blood pressure also belong with a clinician, not a Start button.
End the fast if
- Dizziness on standing, confusion, fainting, chest pain, or severe weakness
- A tremor or dread that is not ordinary hunger
- You take glucose-lowering medicine and feel low
- Food distress: panic, numbness, or a pull toward bingeing or purging

This timer will not pretend
No time cap is flexibility, not a dare. Stage badges are a map, not a lab. Wrong preset:
change mode, the start stays. No account to start. No scale.
