How to Keep Track of a Fasting and Eating Window
Use Simple Fast’s timer, plan options, and home screen widget to track a fasting or eating window.

Tracking a fasting and eating window starts with a schedule you can recognize. Simple Fast gives you a live timer for the current window and a weekly summary you can check later. Use the timer to follow the schedule you chose, then use the widget to glance back at your recorded week.
Choose the plan you want to track
Simple Fast offers four plans: 12:12, 16:8, 18:6, and 20:4. Choose the available plan that represents the window you intend to track. The two numbers describe the fasting and eating hours in that schedule. Keeping one plan in view makes it easier to understand what the timer is showing as the cycle progresses.
If you are comparing the options, focus on the timing each one represents. This is a way to organize your tracking, not a recommendation about which plan to follow. Before changing your eating patterns, consult a healthcare professional.
Check the live timer for your current place
The live timer shows elapsed and remaining time, along with your place in the fasting or eating window. When you want to know where you are in the schedule, open the timer and read those details together. Elapsed time tells you how much of the current window has passed; remaining time shows how much is left according to the plan being tracked.
Make the check useful by asking a simple question: “Am I in the fasting window or the eating window?” Then look at the elapsed or remaining time to orient yourself. The timer is a time-tracking reference for the window you record. It does not verify meals or establish what you ate, so use it to understand the schedule rather than as a meal log.
Use the widget to review the week
The Simple Fast home screen widget shows a weekly summary, completed days, your streak, and average fasting hours. It gives you a glanceable view of your tracking when you want to see the week as a whole. Use the live timer when you need the current window’s details, and the widget when you want a brief weekly overview.
The widget is a summary, not a timer control: it does not start or change a session. It also does not verify meals. If a summary looks different from what you expected, return to the timer and review the schedule you are tracking rather than treating the widget as a complete record of meals.
Keep the record easy to understand
Simple Fast’s core tracker works offline and keeps tracking data in local storage. That makes it possible to use the timer and review your tracking without an account or cloud sync. The app presents the schedule and summaries; your own use of the tracker determines what gets recorded.
A practical routine is simple: choose one of the available plans, check the live timer to understand your place in the fasting or eating window, and use the widget for a weekly glance at completed days, streak, and average fasting hours. Keep each view in its role: the timer explains the current schedule, while the widget summarizes tracking over the week.
