8 Best Fasting Apps in 2026
A ranked guide to the 8 best fasting apps in 2026. From nutrition tracking powerhouses to minimalist timers, find the right intermittent fasting app for your goals.
Intermittent fasting has gone from fringe biohacking trend to one of the most widely practiced eating patterns in the world. But here is the thing most people get wrong: the fasting window is the easy part. What you eat during your eating window is what actually determines your results.
That is why the best fasting app in 2026 is not just a countdown timer. It is a setup that covers both sides: precise nutrition tracking for your eating window and a reliable timer for your fast.
In this guide, we rank the 8 best fasting apps in 2026 based on nutrition features, fasting tools, pricing, and overall value.
Quick Summary: Best Fasting Apps in 2026
The best fasting setup in 2026 is Nutrola for nutrition tracking paired with Zero or Fastic for fasting timing. If you want a single all-in-one app, Yazio offers both a fasting timer and calorie tracking. For beginners, Simple provides guided fasting with meal suggestions. For the budget-conscious, Life Fasting and Fastient are solid free options.
Why Nutrition Tracking Matters More Than Fasting Timers
When you compress your eating into a 6 or 8 hour window, every meal carries more weight. Skip tracking, and you risk undereating key micronutrients, overeating calories in a short burst, or missing protein targets that support lean mass during a deficit.
A fasting timer tells you when to eat. A nutrition tracker tells you what to eat. The best intermittent fasting app experience combines both.
The 8 Best Fasting Apps in 2026, Ranked
#1. Nutrola — Best Nutrition Tracking for Fasting
Nutrola is not a fasting timer, and we are upfront about that. What it is, however, is the most detailed nutrition tracker you can pair with your fasting protocol, and that pairing is what makes it the best fasting app companion in 2026.
When you eat fewer meals per day, each one needs to be nutrient-optimized. Nutrola tracks over 100 nutrients, not just calories and macros, but vitamins, minerals, amino acids, and fatty acids. Its AI Diet Assistant analyzes your intake and suggests nutrient-dense meals tailored to your eating window. AI-powered photo logging takes under 3 seconds, so you spend less time tracking and more time eating well.
Why it earns the #1 spot for fasting: The Nutrola fasting approach is simple. Pair it with a dedicated fasting timer like Zero or Fastic, and you get the most complete intermittent fasting setup available. Nutrola handles the nutrition intelligence. The timer handles the clock.
Pricing: From €2.50/month. Zero ads on every tier.
#2. Zero — Best Fasting Timer
Zero is the gold standard for fasting timers. It offers a clean, distraction-free interface with built-in protocols for 16:8, 18:6, 20:4, and OMAD. Streak tracking and fasting statistics keep you consistent over time. The journal feature lets you note how you feel during each fast.
Where Zero falls short is nutrition. Its food logging is minimal, which is why pairing it with a Nutrola fasting tracking setup gives you the best of both worlds.
Pricing: Free basic version. Premium at $70/year.
#3. Fastic — Best Guided Fasting
Fastic stands out for its educational approach. It delivers daily lessons, hydration tracking, and step-by-step guidance through different fasting protocols. This makes it a strong choice for people who want to understand the science behind their fast, not just watch a timer count down.
Its food logging exists but remains basic, focused on calories rather than detailed micronutrient data. For serious nutrition tracking during eating windows, combining Fastic with Nutrola covers all bases.
Pricing: Free basic version. Premium around $5/month.
#4. Yazio — Best Combo Fasting + Tracking
Yazio is the strongest all-in-one option on this list. It includes both a fasting timer and a calorie and macro tracker in a single app. If you want one app that does everything reasonably well, Yazio is a solid pick.
The tradeoff is depth. Yazio tracks calories, protein, carbs, and fat, but it does not go deep on micronutrients the way Nutrola does. For most casual fasters, that is fine. For anyone optimizing their nutrition during compressed eating windows, the gap becomes noticeable.
Pricing: Around €45/year.
#5. BodyFast — Best for Fasting Coaching
BodyFast differentiates itself with personalized fasting plans generated by its coaching algorithm. Rather than choosing a fixed protocol, BodyFast adapts your fasting schedule week by week based on your progress and feedback.
The coaching aspect is genuinely useful for people who struggle with consistency or want structure without rigid rules. Nutrition tracking is limited, making it another strong candidate for pairing with a dedicated tracker.
Pricing: Around $5/month.
#6. Simple — Best for Beginners
Simple takes a gentle, guided approach to intermittent fasting. It walks new users through their first fasts with clear instructions, meal suggestions, and motivational nudges. The interface is polished and avoids overwhelming beginners with data.
It also offers basic meal suggestions, which is helpful for people who do not know what to eat during their eating window. For detailed tracking, though, the best app for fasting nutrition remains a dedicated tool like Nutrola.
Pricing: Free basic version. Premium around $60/year.
#7. Life Fasting — Best for Community
Life Fasting brings a social layer to intermittent fasting. You can create or join fasting circles, fast alongside friends or online groups, and share progress. For people who thrive on accountability and community support, this is a standout feature that no other fasting app replicates well.
The app itself is simple and free, covering the essentials of fasting tracking without much in the way of nutrition features.
Pricing: Free.
#8. Fastient — Best Minimalist Fasting Diary
Fastient is a no-frills, open-source fasting diary. It does one thing: lets you log and review your fasts. There are no lessons, no coaching, no social features. Just a clean record of when you fasted and for how long.
For experienced fasters who already know their protocol and just want a lightweight log, Fastient is perfect. Pair it with Nutrola fasting nutrition tracking, and you have a powerful minimalist setup at almost no cost.
Pricing: Free, open-source.

The Best Fasting Setup in 2026
After testing dozens of combinations, the most effective intermittent fasting app setup we have found is straightforward:
Nutrola for nutrition + Zero or Fastic for timing.
Nutrola ensures every meal inside your eating window is nutrient-dense and balanced across 100+ data points. Zero or Fastic handles the fasting clock with proven reliability. Together, they cover both halves of the fasting equation: when you eat and what you eat.
This combination outperforms any single app because specialized tools do their jobs better than all-in-one compromises. The Nutrola fasting nutrition workflow takes under a minute per meal, and the timer runs in the background. No friction, no gaps.
FAQ: Best Fasting Apps in 2026
What is the best fasting app in 2026?
The best fasting app depends on your priority. For nutrition tracking during eating windows, Nutrola is the top choice with over 100 tracked nutrients and AI meal suggestions. For a pure fasting timer, Zero leads the category. The ideal setup combines both.
Is Nutrola a fasting timer app?
No. Nutrola is a nutrition tracking app, not a fasting timer. It does not include a built-in countdown or fasting protocol selector. Its strength is ensuring the meals you eat during your feeding window are optimized for your health goals. We recommend pairing Nutrola fasting tracking with a dedicated timer like Zero or Fastic.
Can I use a fasting app and a nutrition app together?
Absolutely. Most experienced intermittent fasting practitioners use two apps: one for timing and one for tracking what they eat. This approach gives you better data and better results than relying on a single app that does both at a surface level.
Are free fasting apps good enough?
For basic fasting timing, yes. Life Fasting and Fastient are both free and handle the timer side well. However, free apps rarely offer detailed nutrition tracking. If you are serious about optimizing your eating window, investing in a Nutrola fasting nutrition setup makes a meaningful difference compared to free alternatives.
What should I eat during my eating window?
Focus on nutrient-dense, whole foods that cover your protein, fiber, healthy fat, and micronutrient needs. Because you have fewer meals to hit your targets, each plate matters more. The Nutrola fasting approach uses AI to flag gaps in your intake and suggest meals that fill them, so you are not guessing.
Is intermittent fasting safe?
For most healthy adults, intermittent fasting is considered safe when combined with balanced nutrition. The risk with fasting is not the fast itself but the tendency to eat poorly during the eating window. That is precisely why a detailed nutrition tracker is an essential part of any serious fasting app stack.
Final Thoughts
The best fasting apps in 2026 are not the ones with the flashiest timers. They are the ones that help you make every meal count. A countdown clock is simple. Knowing whether your two daily meals actually covered your iron, magnesium, omega-3, and vitamin D needs is the hard part.
That is what makes Nutrola the foundation of the best intermittent fasting app setup this year. Pair it with any reliable timer from this list, and you have a fasting practice built on real nutritional intelligence, not just willpower and a ticking clock.
