Do I really need an app for intermittent fasting?

While you can track manually, apps offer structured plans, accurate timers, helpful reminders, progress visualization, and motivational insights. They significantly simplify the process, especially for beginners, making it easier to stay consistent and understand your body's fasting stages.

Are the free versions of intermittent fasting apps good enough?

Yes, many free versions provide excellent basic functionality like fasting timers, simple tracking, and reminders. Premium versions typically unlock personalized plans, advanced statistics, recipes, educational content, or coaching, which can be valuable but aren't essential to start.

What key features should I look for when choosing an intermittent fasting app?

Look for a reliable and easy-to-use timer, the ability to customize fasting schedules, progress tracking (like weight and streaks), clear reminders, and potentially educational resources. Added features like water tracking, recipe libraries, or community support depend on your personal preferences.

Can using an intermittent fasting app guarantee weight loss?

No app can guarantee weight loss on its own. These apps are tools to help you effectively implement and track intermittent fasting. Your results will ultimately depend on your consistency, overall diet during eating windows, lifestyle choices, and individual body response.

Is it safe to start intermittent fasting just by using an intermittent fasting app?

While these apps provide guidance, they are not a substitute for professional medical advice. It's always best to consult with your doctor before starting any new fasting regimen, especially if you have pre-existing health conditions, are pregnant or nursing, or have a history of eating disorders.

Best Intermittent Fasting Apps (Free & Paid)

We are not biased. We test and review every product. Here’s our Methodology.

I was tired of counting calories, eating sad salads, and still not seeing results. So when I heard people raving about intermittent fasting, I thought, “Why not? Skipping breakfast sounds easier than skipping dessert.”

And… it actually works, but only if you can truly stick to it. That’s where the intermittent fasting apps saved me. No guesswork, no forgetting when to eat (or not eat), and way fewer hangry-induced breakdowns.

If you're thinking of trying intermittent fasting, or are already in the game but struggling to stay consistent, these apps are the real MVPs. I tried a bunch, deleted some, and kept only the best. Here's what’s actually worth your time (and hunger).

How I Chose the Best Intermittent Fasting Apps

To ensure this list only includes apps that actually help you fast smarter, I evaluated each one based on:

Fasting Features & Flexibility — Support for popular fasting plans like 16:8, 18:6, OMAD, and the ability to customize your own schedule.
User Experience — Clean, intuitive design that makes tracking easy, even when you're hangry and half-asleep.
Motivation & Guidance — Daily reminders, progress charts, coaching tips, and community features that keep you going when willpower fades.
Education & Insights — Science-backed articles, expert tips, and health data integration to help you understand what’s happening in your body.
Free vs. Paid Value — What’s offered in the free version vs. what’s locked behind a paywall—and whether the upgrade is actually worth it.
Privacy & Data Security — Transparent data policies and secure handling of personal health info, because your progress is yours alone.

Zero is the world's most popular fasting app, perfect for data-lovers who want to see when their body enters 'Fat-Burning Mode' with its unique, science-backed tracker.
More about product
Zero is the perfect guide for anyone ditching calorie counting for metabolic health. I was hesitant about fasting, but the app's one-tap timer made starting my first 16:8 fast incredibly simple. What really impressed me was the Fat-Burning Mode.

Seeing the app show me, in real-time, when my body likely shifted into ketosis was a huge motivator. It wasn't just a passive timer; it felt like a personalized guide. I also loved the expert content, which explained why I was feeling more energetic.

The app is free to download and use; however, for more advanced features like fat burning mode, a premium content library, custom fasting plans, and others, you can buy a Plus subscription. The Zero Plus subscription starts at $9.99.

The daily Streaks and Badges became a fun obsession that genuinely helped me build a consistent habit and see transformative results. A quick note: while it's an iOS superstar, I noticed the Android ratings are lower. Most complaints seem to be about a clunky UI, but the core tracking features I love are all there!

More about product
Fastic is a personalized health experience for anyone who feels that other fasting apps are just glorified timers. I was immediately drawn to its new Protein Fasting mode, which isn't just about when you eat, but what you eat.

The app provided high-protein recipes that helped me feel full and energized, a game-changer compared to just watching a clock. What really impressed me was the Fastic Food Scanner. Curious about my lunch, I snapped a quick photo, and the app instantly analyzed its nutritional content. It was incredibly insightful.

This, combined with my personalized Fastic Score, which tracked my fasting, hydration, sleep, and steps, made me feel like I had a complete picture of my health. It wasn't just about avoiding the yo-yo effect; it felt like building a genuinely healthier, sustainable lifestyle from the ground up.

Fastic operates on a freemium model. The free version provides the core tools needed for intermittent fasting. With Factic Plus available for $14.99 for a month, you get a recipe book, interaction with Fasty (AI chatbot), advanced stats, and more.

Instead of just sticking to one plan, the ‘Coach’ (a premium feature, available at $13.49 for a month) gave me a new, simple fasting schedule every week, which kept things from getting boring. What really set it apart for me were the 100+ recipes tailored for fasting.

It's not just about not eating; the app helps you eat well, too. I also loved the ‘Fasting Stages’ feature, which shows you what's happening in your body as the hours tick by. It’s incredibly motivating to see you've entered the fat-burning or detox phase.

More about product
Window acts as your personal guide, combining a science-based approach with expert guidance. For me, the free version was a great start, with its simple timer, weight journal, and helpful blog. But upgrading to Premium is what made the difference.

I received a personalized fasting program and, most impressively, an individual meal plan. This solved my biggest problem: what to eat when my window opened. The app didn't just track my food; it gave me nutritionist-approved ideas for breakfast, lunch, and dinner.

I also loved the ‘Healthy Challenges’ feature. With this feature, I was able to manage and reduce my sugar intake. It also helped me build a new habit (a healthier one). You can also opt for Window’s Premiu,m which unlocks nutrition and mood tracker, individual meal plans, healthy challenges, and much more.

All these features and much more are available with the premium plans starting at $4.99 for a week. This is one of the best apps for intermittent fasting, offering a complete system that connects your fasts, nutrition, and mood.

More about product
Sunrise Fasting is a beautifully simple and effective guide for your fasting journey. As someone who has tried other apps, I appreciated its clean, to-the-point interface. I set up a custom 18:6 fast, and the live hourglass timer on my home screen widget was surprisingly motivating.

While Sunrise is a beautifully simple tracker for any IF plan, its standout feature is its ability to track location-based fasts. For anyone observing a religious or cultural fast (like Ramadan), it can automatically set your windows based on your local sunrise and sunset.

It’s one of the best free intermittent fasting apps for iPhone, a perfect, uncomplicated companion for both beginners and experienced fasters. You can use the app for free or opt for a subscription plan to access full features.

With a premium plan, you can unlock fasting presets, an ad-free experience, and much more. If you are someone who just wants a reliable tool to track their fasts, earn badges, and stay motivated, Sunrise is for you!

More about product
The DoFasting Intermittent Fasting app starts with a comprehensive quiz to understand your goals, which I found made the process feel very personalized. The app then provides a customized fasting plan, but it doesn't stop there. What truly sets it apart is the integration of workout routines and a 5,000+ recipe library.

More about product
Fastin is a powerful weight-loss tool that guides you on your intermittent fasting journey. It’s built on the idea that you don't need to exercise for 3 hours a day, just control when you eat.

GoFasting is the perfect app for those who want a simple, free, and effective way to start fasting without the complexity. It’s a straightforward tool focused on helping you lose weight and get healthy without needing a specific diet plan or exercise.
More about product
GoFasting is a professional and free fasting tracker designed to make weight loss easy and accessible. I found it to be one of the most straightforward apps available. I used it for a few days and loved the simplicity. All I had to do was pick a plan (I started with 16:8) and tap to start the timer.

The app sent a notification when my eating window opened, taking all the guesswork out of it. It’s not just a timer; it also has a great section with professional articles that helped me understand why fasting works.

This is my top pick for Apple Watch users. FastHabit’s standout feature is its seamless watch integration, letting you track everything from your wrist. It's the clean, no-frills tool for the faster who values convenience above all.
More about product
FastHabit is the perfect app if you find other fasting trackers overly complicated. I was looking for something simple, and FastHabit delivered. Setting my 16-hour fast was effortless, and I loved how easy it was to adjust the timer if my eating window shifted slightly – something other apps often make difficult.

The Apple Watch integration is a standout feature; I could start, stop, and check my progress right from my wrist, which was incredibly convenient during busy days.

What kept me going was the 10-day snapshot showing my fasting 'streak.' Seeing those consecutive days built up was surprisingly motivating. The FastHabit Pro upgrade is typically a one-time purchase (priced at $2.99) rather than a recurring subscription.

It unlocks unlimited stat tracking (the free version often limits history), enhanced reminders (including start/stop alerts and early warnings), and the ability to export your data for personal analysis. All-in-all, the FastHabit Intermittent Fasting app is a clean, efficient app that focuses on the core task of tracking your fasts consistently.

Why Choose Intermittent Fasting Apps Over General Diet Tracking Methods?

While general diet tracking apps focus primarily on what and how much you eat (calories, macros), Intermittent Fasting (IF) is uniquely centered around when you eat. Specialized IF apps are designed specifically for this time-based approach, offering distinct advantages over generic methods.

Here's why you should choose an IF app:

1. Dedicated Fasting Timers

IF apps provide precise timers specifically for tracking fasting and eating windows, often with visual progress bars and reminders for start/end times. General apps lack this core functionality or require manual workarounds.

2. Structured Plans & Guidance

These apps offer various popular fasting protocols (like 16:8, 5:2, OMAD) and guide you through them, simplifying the process, especially for beginners. General diet apps focus on meal logging, not timed eating structures.

3. Targeted Motivation & Insights

Many apps provide motivating features like tracking fasting streaks, showing estimated body stages (like ketosis or autophagy). These apps offer insights specifically related to the benefits of fasting, which general trackers don't provide.

4. Streamlined Focus

Paid and free intermittent fasting apps keep the primary focus on timing. While some offer food logging, their core design simplifies the time-tracking aspect, avoiding the potential overwhelm of detailed calorie/macro tracking unless you specifically want both.

5. Tailored Education

Most apps often include articles, tips, and resources specifically about intermittent fasting science, benefits, and best practices, unlike the broader nutritional focus of general diet apps.

Final Verdict!

So, there you have it – a tour through the intermittent fasting apps ready to transform your health journey from a maybe-someday idea into a daily reality. We've seen apps packed with science, buzzing with community, streamlined for simplicity, and loaded with features to track everything but your cat's nap schedule!

Intermittent fasting isn't about deprivation; it's about harnessing your body's natural rhythms. And with these apps, you're no longer navigating blind.

Pick the app that resonates most, dive in, and start tapping that timer. Your journey to a healthier, more energized you isn't on the horizon – it's ready to start now!
