Using the Clock
The timer as a tool: what a fasting clock is for, how to choose one, what this one does, and what it refuses.
A fasting timer counts hours. It does not clear you, sell 16:8 as an identity, or replace a clinician. Forums treat the app as the method: streaks, badges, and a shop. Those extras are not the clock.
These notes are the tool. What a fasting timer is for is the job. Choosing a fasting timer compares other clocks by the job you already have, including this one. We make MyFastingClock. That is a disclosure, not a ranking. Presets on this clock is the hour buttons on this timer. History on this clock is the list of fasts you already finished on this timer. Open on this clock is the button with no finish time. Fundamentals is the main set of notes. How to make fasting easier stays quieter daily hours. Longer fasts stays a stretch past a day. Open-ended and multi-day fasts is why this timer has no cap. What the stages on the timer mean stays the stage names. From clinic to consumer app is the history of the store listing.

- Part 1: What a fasting timer is for: A fasting timer counts hours. It does not clear you, sell a plan, or replace an exit. What a clock has to do, what this one does, and what it will not.
- Part 2: Choosing a fasting timer: Choose a fasting timer by deciding where it has to live, how long you mean to fast, and what you want besides the hours. We make MyFastingClock, and this page includes it with the other clocks.
- Part 3: Presets on this clock: On this timer, 16:8, OMAD, Custom, and Open are hours you pick. A full circle does not mean your body changed. Not a ranking of 16:8 vs OMAD.
- Part 4: History on this clock: History is the list of fasts you already finished on this clock. You can log a missed fast, correct a time, and see counts of those hours. Those counts do not keep a streak of days, and friends cannot see them.
- Part 5: Open on this clock: Open is the hour button with no finish time. The clock counts until you press End Fast. The line under the hours says there is no time cap. A full ring does not mean the fast is finished.
