Intermittent fasting
The g tracker market is technically simple, but trust is systemically broken: 23 of 47 apps show rating inflation, the real ceiling in the top 47 is 74 points (), and not one app has crossed 80.
Money here is made on traffic, not product depth: an aggressive 25-30 question onboarding funnels users to a paywall before their first tap, inflated ratings drive installs, and retention rests not on value but on how hard the subscription is to cancel (DoFasting, , ).
The top differs from the bottom on one mechanic: an honest timer with minimal start friction and a visible g-phase display (g Tracker Easy Fast, realScore 71) keeps users without tricks, while every app below 40 points shares the same combination of rating inflation and broken core mechanics: the timer resets, history vanishes, editing is unavailable.
The window for a founder is open: a market with huge traffic and no honest leader above 74 points.
Market overview
The niche is captured by apps with inflated ratings and aggressive subscription onboarding: of the 47 apps analyzed, 23 show signs of manipulation, and the market's real shortage is not the tracker itself but an app that simply does not break, does not lose history, and does not raise a paywall before the user has understood why they would pay.

The market's systemic mistake: every app calls itself some variation of "" with a colon, an exclamation mark, or a trademark tacked on, which makes App Store search navigation nearly impossible: users cannot remember which app they actually installed. and look like volume leaders, but live reviews show decay after monetization: Zero sits at textAvg 1.88 against storeAvg 4.82. FastHabit was a minimalist timer until it moved free features behind a subscription. Users leave citing exactly that wording. Apps that do not inflate win either on cleanliness (, realScore 71) or on the Apple ecosystem ( with iCloud sync, realScore 72). Both are honest, both sit in the top 5 by real score.
Audience
"Intermittent fasting" is not one customer. Inside are different people with different jobs, and they pay very differently. First you choose who you build for.
Where the money is
Where users come from
Channels visible right in the reviews: people say themselves how they found the app and why they installed it. This is the niche's distribution.
Store search: a simple timer without a subscription12
The dominant channel: people look for a fasting app on their own and repeat one request in almost every review, a simple timer without a subscription or extra bloat. The niche is overrun with paywalls, so an honest simple and free in the listing collects installs by itself.
This is the app I’ve been looking for! Function over all the money-making shenanigans. Thank you, thank you, thank you.
I have been looking for weight loss apps for 2 years! Everyone wants a subscription or u can’t use it. Not this on!
TikTok, Instagram, and Twitter ads6
Fasting app quiz funnels run in every feed and genuinely bring people in, but the ads systematically promise free while an expensive subscription waits inside, and reviews record it. An honest ad offer here is a competitive advantage all by itself.
This app was an AD on my tiktok so I tried it, it is one of those where it makes you pay $2.50 PER WEEK!
It mostly works but kept reading about fasting then saw this app on Twitter so installed it and giving it a go.
Moving on after the death of Life app2
The shutdown of the popular tracker Life dumped seasoned loyal fasters onto the market, who cycled through replacements and even paid for duds. Dying competitors in this niche are a ready-made capture moment for a Life replacement page.
I was using the paid version of the Life app, but when they shut down, I had to find a replacement. I tried a bunch of apps and even paid for a few that I will never use
Since the Life app has shut down I've been searching for as good or better replacement for both shorter & longer fasts.
A recommendation at the start of fasting1
A newcomer just starting intermittent fasting gets the app recommended along with the method itself, usually in communities and among friends. The moment of entering the practice is the point where a recommended tracker gets installed sight unseen.
Just started IF and this app was recommended.
Honest rating
The same hundred apps in two scoring systems. Switch and watch the storefront star diverge from what people actually write in reviews.
Intermittent Fasting Tracker:4.9 in store · genuine · 48,362 ratings74our scoreA clean intermittent fasting timer with no clutter. Install it, open it, and the countdown starts immediately, surfacing in Dynamic Island and on the lock screen.
The app lives in Dynamic Island and on the lock screen, giving you fasting status at a glance without unlocking your phone. Users consistently call this system-level integration the app's biggest win.
No way to edit a timer once it's started or after it ends, so a misclick means a lost record. No sync between iPhone and iPad, so your data only exists on one device.
Anyone who wants a single-purpose tool with no extras: tap once, the timer runs, the number is always visible in Dynamic Island.
Easy Fast Tracker: FastMinder4.7 in store · genuine · 330 ratings72our scoreThe best value-for-reliability pick in the category. Includes a Watch app, a Mac app with iCloud sync, Live Activities, widgets, and educational fasting stages. A go-to choice for users who left the Life app. The paid barrier at install hurts conversion.
Mac plus iOS sync over iCloud is unique in this category. Educational content explaining what your body is doing at each fasting stage. A first-class Watch app with detailed on-screen info.
A paywall hits users on the main screen before they can try anything. The custom notification takes up too much space and is not configurable. Problems entering a future fast start time (the date resets).
Experienced IF practitioners who are invested in the Apple ecosystem (Watch, Mac, iPhone) and already know why they need a tracker. Works well for people running varied protocols including extended fasts.
Fasting Tracker • Easy Fast5.0 in store · genuine · 7,832 ratings71our scoreThe cleanest timer in the category. Shows the current metabolic phase (gluconeogenesis, fat burning, ketosis) right on the dial, which genuinely helps you push through. The free version is functional, paid adds programs and extra stats. Main downside: no sync between iPhone and iPad.
A live fasting-phase display tied to elapsed hours. Users say this is exactly what keeps them inside their fasting window until the end.
No automatic schedule repeat: you have to manually start a new fast every day.
Any IF practitioner from beginner to advanced who wants clear visual phase feedback without extra screens.
Daily Fast4.8 in store · genuine · 3,477 ratings71our scoreDaily Fast is a rare minimalist tracker with no subscriptions and no attempt to bloat the feature set. Users come back to it after trying more complex apps. Main weaknesses: notifications can miss and there is no widget.
A built-in schedule means you never have to manually start or stop. The app knows when you are fasting. Zero monetization pressure and no lifestyle questions on launch.
Notifications about the approaching eating window are unreliable. You cannot edit past-day times. Does not support fasts longer than 24 hours.
An experienced 16:8 practitioner who wants a quiet, accurate timer with no upselling and no subscription.
Intermittent Fasting Tracker ⁺4.9 in store · genuine · 939 ratings68our scoreA gamified tracker where a virtual garden grows with your fasting hours. Also tracks water, menstrual cycle, and mood. A lock screen widget with a countdown is one of its key features. A lifetime purchase option lowers the barrier.
The growing virtual garden mechanic creates an engagement loop. Users say they do not want to kill their plant. Toggleable modules let you keep only the trackers you need without a cluttered home screen.
Custom fast durations outside of presets require a paid upgrade. There is no way to transfer data between iOS and Android, so your history and garden are gone if you switch platforms. Widgets show only the timer, not the garden.
People who need game-like motivation to build a fasting habit, especially a younger audience.
Intermittent Fasting Timer4.8 in store · genuine · 800 ratings68our scoreA minimalist timer with no subscriptions. Does one thing honestly. Main flaw: stats are calculated incorrectly. The 7-day average includes all data from the beginning of use, not a rolling week. Weight entries have no year, so data from multiple years gets mixed together.
One start/stop button, an Apple Watch widget, no pushy notifications, and no paid pressure. You can also backdate the start time of a fast.
Statistics use a running total instead of a sliding window, making them misleading. Weight log entries show no year, so multi-year data becomes unreadable. Cannot log more than one fast per day.
Anyone who wants to tap a button and stop thinking. No education, no progress charts, just a clean timer with a weight log.
Cronometer: Calorie Counter4.8 in store · doubtful · 93,564 ratings62our scoreThe most nutritionally detailed free food tracker available, covering micronutrients alongside macros and including a web version. Loosely connected to fasting as a practice.
The only free tracker that breaks down not just macros but micronutrients (vitamins, minerals) with per-meal detail. The barcode scanner recognizes almost everything without a miss.
After a recent update, search surfaces branded products above generic names, turning a simple query like 'banana' into a multi-step hunt. This breaks the core fast-logging use case.
People who want full control over their diet with a focus on nutrients rather than just calories, and who are not looking for a dedicated fasting timer.
Sunrise - Intermittent Fasting4.8 in store · doubtful · 9,656 ratings62our scoreA minimalist free tracker with no subscription pressure. Core feature: a clean timer with manual start and end entry, a monthly calendar view, and basic weight tracking. Breaks after some updates, with the widget failing to reset and sessions not saving on exit.
The ability to log a past fast retroactively and see a color-coded tile for the entire month keeps the feeling of a streak going.
No daily reminders on a set schedule. Users have to remember to start the timer themselves.
An experienced 16:8 or 18:6 practitioner who wants an honest archive without a subscription or extra screens.
