Intermittent fasting app, without the noise

Intermittent fasting is a pattern of eating windows and fasting windows. Stay at Zero is built for that pattern alone: start a timed or open-ended fast, keep an honest history, and see streaks on a calendar — not a full nutrition suite.

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.

Use it as a guest on your device. The rich core (fasting timer, calendar, stats) stays free — without nagging paywall modals in daily use. Account cloud sync is work in progress and is not required to use the app.

What an intermittent fasting app should do

Show whether you are in a fast, how long it has run, and what your weeks look like. Stay at Zero keeps completed and abandoned fasts honest so streaks reflect real ≥14h sessions — not vanity metrics.

If you are looking for meal photos, protein goals, or grocery plans, this is not that app — and that is intentional.
