Now more and more people are trying the new dietary method of intermittent fasting. As a dietary method, intermittent fasting has rapidly become popular worldwide in recent years, attracting a large number of people to try it. This dietary pattern is not only considered an effective weight loss method, but also believed to bring benefits to physical and mental health. What is intermittent fasting? Intermittent fasting is a dietary pattern that cycles between fasting and a normal diet. It doesn't specify which foods you should eat, but when you should eat them. Intermittent fasting does not involve tracking calories. This dietary approach is mainly achieved by limiting the daily eating time, rather than by accurately calculating the amount of calories or protein, fat, and carbohydrates consumed. HealthKit: We import your exercise data from Apple Health to help you understand your daily exercise routine. The intermittent fasting app will provide you with: Fasting Tracking: Intermittent fasting is tracked according to your fasting plan, and you can check your fasting progress at any time to see which stage of intermittent fasting your body is currently in. Weight Tracking: Record the trend of weight changes through daily weight check ins. Drinking water tracking: Set daily drinking water goals and track completion status.

Fasting made simple, not a second job. If you have downloaded a fasting tracker only to find it nagging you with pop-ups, pushing premium meal plans, and treating every missed window as a moral failure, Intermittent Fasting Kit is the calm alternative. It is built for people who want the benefits of time-restricted eating without the obsession — a quiet fasting timer that runs the clock, then steps out of your way. The philosophy is simple: a fasting app should give you the science and the schedule, and let you live your life around it. It is designed for adults running 16:8 around busy weekdays, the long 20:4 or OMAD on slower ones, 5:2 around a night-shift rota, or 14:10 as a gentle entry into intermittent fasting and weight loss. Every feature described below is unlocked only with an auto-renewable subscription purchased inside the app. New users receive a 3 day free trial; you may cancel anytime during the trial to avoid being charged. Open the app and start a fasting window with one tap. A clean progress ring shows where you are in the fast, while a stage indicator marks the shifts from glycogen depletion into ketosis, autophagy and growth hormone release, so the eating window stops being abstract and starts feeling like a guided fasting clock. Gentle notifications open and close the window at the right time, the Live Activity keeps the countdown alive in the Dynamic Island and on the Lock Screen, and Apple Watch complications let you check in from your wrist without unlocking the phone. Weight tracking syncs with Apple Health, water intake sits alongside the fast, and streaks and milestones live in your history without punishing the days you broke a window early. Custom fasting protocols stretch beyond the presets, so a 24-hour reset, a one-meal-a-day rhythm or a personal 17:7 schedule fit just as cleanly as the classics. A fast tracker history shows the longest fasts, the average duration and the patterns across weeks. The fasting journal layer lets you note mood, sleep, hunger and energy alongside each fast, so the meal timing experiments you run on yourself are visible later rather than lost to memory. Edge cases are handled with care — accidental early breaks, paused fasts during travel, time-zone shifts and missed start taps all stay editable without lecturing. The app ships in 39 languages with full accessibility, VoiceOver, Dynamic Type and high-contrast support. Your fasting log stays on this device — no account, no cloud upload, no third-party server in the loop. Everything works offline, including notifications, widgets and the timer itself. Whether you are using it as a fasting coach, a fasting journal or simply a quiet fasting schedule that lives in your pocket, it stays calm — a tool for time-restricted eating rather than a streak-shaming game. Unlock with Pro: • Unlimited fasting history (free tier: last 14 days) • All widgets, themes and StandBy layouts • Advanced analytics — weekly averages, longest fasts, patterns • Custom fasting protocols beyond the presets • Data export in CSV and JSON Subscription Pricing & Terms Features require a subscription.

Verdict
The clearest difference is monetization model: 16 at free with in-app purchases against Intermittent Fasting Kit's subscription. 16 also leads on update cadence (every 9 days vs every 6 weeks) and ratings volume (54 vs 1). Intermittent Fasting Kit's advantage is rating (5.0 vs 4.7). On price, ads, in-app purchases and device support there is nothing between them.
