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.

Verdict
The clearest difference is monetization model: FastingCat at free with in-app purchases against Intermittent Fasting Kit's subscription. FastingCat also leads on update cadence (every 6 days vs every 6 weeks) and ratings volume (56 vs 1). On price, rating, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Intermittent Fasting Kit sells 3 in-app purchases, starting at $2.99 per 7 days and FastingCat sells 10 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for Intermittent Fasting Kit against 4.9 for FastingCat. That said, the two scores are not equally well evidenced: FastingCat has 56 ratings behind it against 1, so its average is the more settled of the two.
Intermittent Fasting Kit ships an update every 6 weeks, FastingCat every 6 days. The most recent releases landed on September 28, 2026 and October 24, 2026 respectively.
