Frequently Asked Questions

How do I set my eating hours?

When you first open the app, set when you usually start and stop eating on most days. This becomes your Normal day. To change it later, open Settings and tap "Edit normal day." You can start with a suggested plan or set your own times. Eating hours must last at least four hours and can cover the full day.

Do I need to start or stop a fast?

No. Fast:Protocol checks the plan for the current calendar day. It shows YES during your eating hours and NO before and after them. The next day's plan takes over at midnight.

How does the app choose today's plan?

A one-day change in Schedule has first priority. If there is no one-day change, the app checks your Weekly plans. Your Normal day applies when neither of those exists.

Can I change the plan for one date?

Yes. Open Schedule, select the date, and change its eating hours. That change applies only to the selected date. You can change today or plan a future date without changing your Normal day.

How do notifications work?

You can receive a reminder when eating hours begin and another one hour before eating hours end. Turn either reminder on or off in Settings. The app schedules these notifications on your device.

Is the app free?

Yes. Fast:Protocol is free. It has no ads, paywalls, or premium tiers.

Do I need an account?

No. There is no sign-up, no login, and no email required. Open the app and start fasting.

How do I use the Home Screen widget?

Long-press the Home Screen, tap the add button, and search for "Fast:Protocol." Choose a widget size and add it. You can also add Fast:Protocol to the Lock Screen. The widgets show whether you can eat now and when the answer changes.

Does the app work with night shifts or unusual schedules?

You can place eating hours anywhere within a calendar day and create different plans for selected weekdays. One eating window cannot cross midnight. If you eat on both sides of midnight, set each calendar day's hours to match your routine.

Can I change the app's appearance and time format?

Yes. Settings lets you choose an app background and switch between 12-hour and 24-hour time.

Is my data stored anywhere?

Your eating hours, plans, preferences, and widget status stay on your device. Fast:Protocol does not collect or transmit this information.
