Fasting timer for timed and open-ended fasts

Set a goal in hours that matches your intermittent fasting window, or run an open-ended timer for longer fasts. Stay at Zero keeps the screen focused on the clock and your next action — start, end, or adjust — without burying you in side features.

Goals are hours, not a meal plan: 16h is 16:8, 18h is 18:6, 20h is 20:4. 14h is 14:10; 36h and open-ended are for longer fasts. You track the fast — the eating window stays yours.

History lands on the calendar and in statistics so the timer is part of a habit view, not a disposable stopwatch. Guest mode works today; account sync is work in progress. No nagging paywall modals in daily use.
