    What is the Intermittent Fasting Timer?

    Start your fast with one tap and see exactly how long you have been fasting, when your eating window opens and which stage your body is likely in. Choose a plan such as 16:8, 18:6, 20:4 or OMAD (23:1). Your current fast and recent history are saved on this device, so you can close the page and come back.

    How to use the Intermittent Fasting Timer

    1. Choose your fasting plan.
    2. Press Start fast when you finish your last meal (or set the start time).
    3. Press End fast when you eat. Your fast is saved to history.

    Common plans

    • 16:8 – fast 16 hours, eat within 8 (e.g. 12 pm – 8 pm).
    • 18:6 and 20:4 – longer fasts for experienced fasters.
    • OMAD – one meal a day.

    Important

    Fasting is not suitable for everyone – especially during pregnancy, for people with diabetes or eating disorders, or on certain medicines. Talk to a doctor first. Stay hydrated.

    This Intermittent Fasting Timer is 100% free, needs no signup and runs privately in your browser – on phone, tablet or computer.
