About FitFast - 간헐적 단식, 체중 감량 기록 타이머
■ Timers are free forever
Fasting timers, a 6-step metabolic zone timeline, records and calendars, weekly achievement rates, weight and water tracking, and export and backup features.
FitFast does not lock down any of these features that other apps sell for a fee.
It is a promise that we will not hold your body's records hostage.
■ If a company dinner is scheduled, we will move the window for you.
Try entering "Company dinner tonight at 7:30 PM."
We will tell you where to move the meal window to ensure you can sit there while staying on time,
why we calculated it that way, and even how to get back to your normal rhythm over the next few days.
Overtime, lunch appointments, weekend brunches, travel, workouts—we calculate based on actual schedules.
If the schedule is longer than the meal window, we also suggest alternatives such as "Lower your goal for today" or "Eat only for the latter part of the schedule."
■ It doesn't drop to zero even if you miss a day
FitFast does not have consecutive days. It views achievement rates on a weekly basis.
We recognize it as an achievement even if you only meet 92% of your goal.
If you miss the target the next day, we will show you how to get back on track, such as, "If you delay your first meal by one hour, this week's average will return to normal." This is to ensure you don't overexert yourself trying to stick to the numbers.
■ So, What Should You Eat?
We will tell you what is best to eat first after finishing your fast.
You need to start differently for 16-hour and 24-hour fasts.
We guide you toward foods you actually reach for, such as seaweed soup, porridge, and soft tofu, and we also explain why you should eat slowly after exceeding 24 hours.
■ We Will Show You Why We Make These Suggestions
We will review your records from the past two weeks and suggest whether to raise or lower your goal for the following week.
We will then lay out the basis for that decision—achievement rate, average fasting time, and fluctuations in your start time—exactly as it is.
Please apply it only after you have understood and accepted it.
The weekly report identifies recurring patterns, such as, "Friday is the weak link."
It is often a scheduling issue, not a matter of willpower.
■ Safety First
Fasting isn't good for everyone.
If you are pregnant or breastfeeding, under 18, have a history of eating disorders, Type 1 diabetes, or are underweight
FitFast automatically turns off goal time suggestions and coaching. You can continue using your timer and records.
You can also read about signs to stop and precautions for fasting for more than 24 hours right within the app.
It displays a warning if you lose more than 1% of your body weight in a week.
■ Records Only on This Device
Fasting time, weight, hydration, and health status—they are not sent to a server.
No account is required. All features work perfectly fine even in airplane mode.
You can export your entire record as CSV or JSON at any time. It doesn't prevent you from moving to another app.
You can set your start and end times to past times at any time.
To prevent situations like, "I ate last night, but the timer shows 30 hours,"
the app notifies you first if the timer goes significantly past your goal.
