The best fasting apps
Starting price$69.99 per year
Free planYes
Zero is the fasting app most people should try first. The timer is clear, starting a fast takes one tap, and presets cover common schedules such as 16:8, 18:6, and OMAD, so a beginner does not have to build a schedule from scratch. A fasting history, journal, and mood graph help you see patterns over weeks, such as which days are easiest and when hunger or low energy appears. That history is useful for adjusting a plan, rather than guessing from memory.
The free tier covers the core timer and basic tracking, which is enough for many users who only need a reliable way to mark fasting and eating windows. Zero Plus, listed at $69.99 per year in recent app store research, adds deeper analytics, coaching content, and food logging features, including a protein-focused score on the current homepage. For users who want fasting plus full meal planning, Yazio or MyFitnessPal may be a better fit. For users who want a focused, low-friction fasting timer, Zero is the strongest default on this list.
What we like- Simple one-tap timer with common presets
- Journal, mood tracking, and educational content
- Syncs with Apple Health and Apple Watch
Watch out for- Advanced analytics and coaching sit on the paid plan
- Meal tracking is less deep than a full nutrition app
Starting price$11.99 per month
Free planYes
Fastic pairs a fasting timer with the kind of guidance that helps a beginner stay consistent. The free version includes a timer, basic statistics, and water tracking, so you can start without paying. As you fast, the app shows body-status stages, which give a simple sense of what is happening during a fast, and step counting adds a basic activity view. That combination makes Fastic feel less like a stopwatch and more like a daily companion for a new routine.
The paid plan, listed at $11.99 per month in recent research, adds the full recipe library, daily challenges, and deeper coaching content. Recipes matter for fasting, because what you eat in your eating window affects how you feel during the next fast, and Fastic offers many whole-food recipes to choose from. The main limit is platform support: recent reviews note that Fastic lacks an Apple Watch app, which may matter if you want wrist notifications. For beginners who want hand-holding, recipes, and a friendly timer, Fastic is a strong pick.
What we like- Timer plus water and step tracking
- Large recipe library on the paid plan
- Body-status tracking through fasting stages
Watch out for- Full recipe and challenge features require a paid plan
- No Apple Watch app noted in recent reviews
Starting priceSee website
Free planYes
BodyFast builds a personal weekly plan around your goals, rather than asking you to pick a schedule and stick to it alone. After a short setup, the app creates a plan with fasting windows, coaching tips, and challenges, then adjusts the plan week by week. That structure helps people who have tried fasting before and struggled to stay consistent, since the next week is already planned when the current week ends. Recipes and a community group add support beyond the timer itself.
The free tier covers weekly schedule planning and basic tips, while the coach, full challenges, and deeper plan features sit on a paid plan. Readers should check the current price in the app store, since BodyFast pricing varies by plan and region, and the homepage may load in German or another local language depending on location, though the app itself supports English. For users who want a guided plan with a coach, rather than a simple timer, BodyFast is one of the most structured options here.
What we like- Personal weekly fasting plans
- Daily coaching and challenges
- Recipes and community support
Watch out for- Coach and full plan features require a paid plan
- Homepage may load in a local language depending on region
Starting priceSee website
Free planYes
Simple treats fasting as one part of a wider health plan, not as the whole plan. Alongside a fasting timer, it offers a food scanner, feedback on meals, water and tea tracking, and activity plans including walking, yoga, and Pilates. A coach feature gives proactive, personalized support, and the homepage highlights a personal plan that adapts to progress. That breadth suits users who want help with eating habits, activity, and fasting together, rather than a timer in isolation.
The trade-off is complexity. If you only want to start and stop a fast, Simple has more screens and prompts than Zero or Fastic, and the full coaching experience requires a paid plan, so readers should confirm current pricing in the app store before subscribing. Simple also includes nutrition expert content and meal guidance that can help a beginner learn what to eat in an eating window. For users who want coaching and food logging alongside fasting, Simple is a well-rounded choice.
What we like- Personal plan with food scanner and feedback
- Coaching support and activity plans
- Water, tea, and food tracking in one place
Watch out for- Full coaching features require a paid plan
- Focus is broader than fasting alone, which may feel busy for timer-only users
Starting priceSee website
Free planNo
DoFasting offers a structured program for users who want a clear path, not just a timer. The homepage notes seven popular fasting schedules, a custom daily schedule, and weekly summaries that highlight areas for improvement. That weekly review is useful, because it turns a month of fasting into a set of small, visible steps, rather than a single long effort with no feedback. Guidance is aimed at both beginners and experienced fasters, with challenges and milestones to mark progress.
The main program sits behind a paid plan, so DoFasting is not a free-first pick. Readers should check the current price and trial terms in the app store, since pricing varies by plan length. Food and calorie tracking are included in a basic form, but users who want a large food database or detailed macro tracking will find Yazio or MyFitnessPal more complete. For users who want a structured, program-led approach to fasting, with a schedule and weekly feedback, DoFasting is a solid option.
What we like- Seven popular fasting schedules
- Custom daily fasting schedule
- Weekly summaries and progress tracking
Watch out for- Main program requires a paid plan
- Food tracking is less complete than Yazio or MyFitnessPal
Starting price$6.99 per month
Free planYes
Yazio is the best pick when fasting and nutrition matter equally. The free tier includes a fasting timer for common plans, plus barcode scanning and basic nutrient tracking, so you can see both your fasting window and what you eat inside it. That combined view helps with a common fasting problem: eating too little protein or too few nutrients in a short window, which can leave you tired or hungry the next day. Pro, listed at $6.99 per month or $47.90 per year in recent research, adds advanced fasting plans and full nutrient detail.
The app also offers thousands of recipes tailored to goals and preferences, and syncing with fitness trackers adds steps and activity to the same view. For users who only want a timer, Yazio may feel like more app than needed, and Zero will be simpler. For users who want to track food, fasting, and activity in one place, without switching between three apps, Yazio is the most balanced choice on this list.
What we like- Fasting timer for 16:8, 5:2, and 6:1 plans
- Barcode scanning and nutrient tracking
- Large recipe library
Watch out for- Advanced fasting plans require the Pro plan
- Nutrition tracking can feel detailed for timer-only users
Starting price$19.99 per month
Free planYes
MyFitnessPal is best known as a nutrition app, and fasting tracking sits inside that larger system. The free version covers calorie and macro tracking, barcode scanning, and a huge food database, which helps users who already log meals and want to add fasting windows to the same diary. Premium, listed at $19.99 per month or $79.99 per year in recent research, adds fasting tracking, an AI nutrition coach, meal scanning by photo, and voice logging, among other features.
That Premium price is higher than a fasting-only app, so MyFitnessPal only makes sense if you already use it for food tracking, or if you want the largest food database available. For a user who logs meals daily and wants fasting data layered on top of that log, without switching apps, it is a practical choice. For a user who only wants a fasting timer, Zero, Fastic, or Yazio will be cheaper and simpler. MyFitnessPal also syncs with many fitness apps and devices, which helps keep steps, weight, and workouts in one place.
What we like- Very large food database with barcode scanning
- Fasting tracking on Premium
- Syncs with many apps and devices
Watch out for- Fasting features are Premium-only
- Premium price is higher than most fasting-only apps
How we chose
We compared apps that are available in the United States in 2026, support intermittent fasting tracking, and are actively maintained on iOS and Android or as a companion app. We checked each vendor homepage to confirm the product loads and belongs to the named app, and we reviewed pricing pages, app store listings, and public help material for timer features, plans, coaching, food tracking, and free tiers. We favored a mix of timer-first apps and nutrition-first apps, so readers can choose based on whether they need a simple timer or a full food and fasting system. We did not claim hands-on testing, and readers should confirm current prices in the app store, since subscription prices change often.
How to choose a fasting app safely
This is not medical advice. Fasting can affect blood sugar, medication, energy, and mood, and it is not suitable for everyone. People who are pregnant, breastfeeding, under 18, living with diabetes, an eating disorder, or another medical condition, or taking medication that affects blood sugar or blood pressure, should talk with a clinician before starting a fasting plan. Stop fasting and seek medical advice if you feel faint, dizzy, or unwell.
Start with a gentle schedule
A 12:12 or 14:10 schedule, with a shorter fasting window, is easier to sustain than a long fast, and it lets you learn how your body responds. Move to a longer window only if you feel well, sleep well, and can eat enough protein and nutrients in your eating window.
Pick the app that matches your habit, not the most features
A simple timer you actually open each day beats a complex app you ignore after a week. If you need coaching, choose BodyFast, Simple, or DoFasting. If you need food tracking, choose Yazio or MyFitnessPal. If you need only a timer, choose Zero or Fastic.
Watch protein, water, and sleep
Fasting works best alongside adequate protein, water, and sleep, especially for people who exercise. Use the app to track water and meals, not just fasting hours, and note how sleep and energy change week by week. If a plan leaves you constantly tired or hungry, shorten the fasting window or talk with a clinician.
Check what is free before you pay
Many fasting apps show a free timer, but lock plans, coaching, and recipes behind a subscription. Use the free tier for a week, check which features you actually use, and only then choose a monthly or yearly plan. Yearly plans are cheaper per month, but only if you will use the app for a full year.
Frequently asked questions
What is the best fasting app for beginners?
Zero and Fastic are the best beginner picks. Zero offers a simple timer and presets, while Fastic adds guidance, water tracking, and recipes. Start with a gentle schedule and use the free tier before paying for a plan.
Are fasting apps free?
Many offer a free tier that covers a basic timer, but coaching, advanced plans, and full recipe libraries usually require a paid plan. Zero, Fastic, BodyFast, Simple, Yazio, and MyFitnessPal all have free features, while DoFasting mainly requires a paid plan.
What fasting schedule should I start with?
A common starting point is 16:8, with 16 hours of fasting and an 8-hour eating window, but a shorter window such as 12:12 or 14:10 is easier for many beginners. Choose a schedule you can sustain, eat enough in your window, and adjust based on energy, sleep, and advice from a clinician if needed.
Can a fasting app help with weight loss?
A fasting app can help you track windows, meals, and habits, which may support weight management for some people, but it does not guarantee weight loss. Results depend on overall diet, activity, sleep, and health, and no app should replace medical advice for weight or metabolic conditions.
Do fasting apps work with Apple Watch or fitness trackers?
Yes, in many cases. Zero syncs with Apple Health and Apple Watch, Yazio and MyFitnessPal sync with fitness trackers, and other apps offer step tracking inside the app. Check the app store listing for the exact devices supported before buying.
Is fasting safe for everyone?
No. Fasting is not suitable for everyone, including people who are pregnant, under 18, living with certain medical conditions, or taking certain medications. Talk with a clinician before starting, and stop if you feel unwell. This guide is for general information only and is not medical advice.
