Can Yazio Track Fasting and Calories?

Yes — Yazio tracks both fasting and calories in one app. That's its core selling point. But Nutrola does both too, plus AI photo + verified DB + 100+ nutrients at €2.50/mo.

Yazio built its reputation by combining two of the most-used health tracking features into a single subscription: an intermittent fasting timer and a daily calorie counter. For users juggling a 16:8 window and a calorie deficit, that integration matters. You stop toggling between a fasting app and a nutrition app, and you start seeing both sides of the weight-loss equation in one dashboard. That is a real, repeatable reason Yazio has grown as fast as it has.

The fair follow-up question, though, is whether Yazio's combo is actually the best combo in 2026. Fasting timers are not hard to build — they are essentially a clock — and calorie tracking is a solved problem on the phone. Where apps differ is in nutrition accuracy, database verification, AI-powered logging, micronutrient depth, language support, and subscription price. On all of those fronts, Yazio sits in the middle of the market. This guide answers the core question first, then shows where competitors, particularly Nutrola, have caught up and moved ahead.

How Yazio Handles Fasting + Calories

Yazio's fasting tracker covers every popular protocol: 12:12, 14:10, 16:8, 18:6, 20:4, and custom windows. You set your eating window, start the timer, and the app visualizes your progress as a ring that fills through the fasting period. Notifications alert you when fasting begins, when it ends, and at the halfway point if you want the reinforcement. Historical data is preserved so you can see fasting streaks, average window length, and consistency week over week.

On the calorie side, Yazio maintains a large food database — the exact verified vs crowdsourced ratio is not public — with barcode scanning, recipe import, and daily macro breakdowns for protein, carbs, and fat. The dashboard presents your daily calorie budget, your logged intake, your remaining calories, and your macro split in a clean, colorful layout that has earned the app awards for interface design. Apple Health and Google Fit integration feed activity data into your calorie budget automatically.

The real value is the integration layer between the two systems. When you end a fasting window, the app treats your first meal of the day as the start of the eating window and begins counting calories inside that window specifically. Your fasting hours become context for your calorie logs, and you can see patterns such as "I tend to overeat when I break a 20-hour fast." That linkage — fasting context attached to calorie behavior — is what users pay for, and it is the honest reason Yazio deserves credit in this category.

Where Yazio's Combo Falls Short

The combo works. The question is whether the underlying nutrition tracking is strong enough to anchor a serious weight-loss or body-composition journey, and this is where Yazio's limitations show.

Limited nutrient depth. Yazio tracks calories, protein, carbs, and fat by default, with some additional fields for fiber, sugar, and sodium. For users who care about micronutrients — vitamin D, B12, magnesium, iron, potassium, omega-3 balance, saturated-fat ratios — the data simply is not there. Intermittent fasters are often the same people optimizing for metabolic health, and metabolic health is a micronutrient story as much as a calorie story. Stopping at macros leaves the most nutritionally literate segment of the audience underserved.

Crowdsourced database. Much of Yazio's food database is user-submitted, which means the same item can appear multiple times with different nutrition values, and the "most popular" entry is not necessarily the most accurate. For a quick log of a supermarket product, this is fine. For anyone logging home-cooked meals, restaurant items, or international foods, the variance compounds, and your daily totals can drift 10 to 20 percent from reality without you noticing.

No AI photo logging. Yazio's logging flow is barcode-first and search-first. There is no photo-to-meal AI that identifies a plate, estimates portions, and returns nutrition in seconds. In 2026, this is the feature that separates a ten-second log from a ninety-second log, and it is the single biggest adherence multiplier in calorie tracking. Without it, long fasting days that end with a large meal can feel like a chore to log accurately.

Recipe import is limited. Yazio's recipe-import quality depends on database coverage of the ingredients you paste. If the recipe uses anything outside the most-logged ingredients, manual cleanup is required. For anyone who cooks from a rotation of recipe blogs or Substacks, this shows up as friction every week.

Price creep. Yazio's pricing varies by region but trends toward premium. Year-over-year, the PRO plan has climbed, and the app pushes upsells in the free tier regularly. Users who signed up for the combo at a lower price are steadily paying more for the same feature set.

None of these make Yazio a bad app. They make it a competent mid-tier option in a market where newer entrants have moved faster on nutrition depth, AI, and pricing.

Other Apps That Do Both

If the Yazio combo is exactly what you want but you suspect there is a better version of it, here are the realistic alternatives in 2026.

Nutrola. Built-in fasting timer with eating-window tracking, full calorie and 100+ nutrient tracking, AI photo logging in under three seconds, 1.8 million+ verified database entries, 14 languages, zero ads, and a €2.50/month price point with a free tier. Nutrola is the direct replacement for Yazio when you want both features without trading away nutrition accuracy or modern AI.

MyFitnessPal + manual fasting tracking. MyFitnessPal does not include a dedicated fasting timer, but many users track their eating window manually by logging their first and last meal times. The calorie side is strong (20M+ database, widely used), but the free tier is heavily ad-supported and premium is substantially more expensive than Yazio. If you are already on MFP, adding a free fasting timer app like Zero covers the gap — at the cost of using two apps instead of one.

Simple + MyFitnessPal combo. Simple is a fasting-first app with coaching prompts and a clean timer UI, and users who prefer specialist apps sometimes pair Simple for fasting with MFP for calories. This is the "best of breed" path, but it doubles your subscriptions, splits your data across two platforms, and removes the fasting-calorie integration that made you consider Yazio in the first place. Most users who try this combo eventually consolidate.

Cronometer with manual fasting. Cronometer leads the market on nutrient accuracy and verified data but does not include a native fasting timer. It is the best calorie tracker for nutrition depth, not the best for the Yazio combo. Pairing it with a separate fasting app works but recreates the exact fragmentation Yazio solves.

The takeaway: the only app that genuinely matches Yazio's combo proposition in 2026 — fasting timer plus calorie tracking in a single subscription — while also fixing Yazio's gaps on AI, verified data, micronutrients, and price, is Nutrola.

How Nutrola Handles Fasting + Calories

Nutrola was built calorie-tracking-first, then added fasting as a first-class feature rather than a secondary module. The result is tighter integration, more accurate nutrition data, and modern AI features that Yazio has not yet shipped.

• Fasting timer with every popular protocol. 12:12, 14:10, 16:8, 18:6, 20:4, 23:1 OMAD, and full custom windows. Start, stop, and edit any fast retroactively.
• Eating-window tracking integrated with calorie logs. Your logged meals automatically attach to the current eating window, and the dashboard shows calories consumed inside versus outside the window for honest self-assessment.
• AI photo logging in under three seconds. Snap a plate, the app identifies foods, estimates portions, and logs verified nutrition data. The fastest path from "just ate" to "logged."
• 1.8 million+ verified database entries. Every item reviewed by nutrition professionals. No crowdsourced variance, no five duplicate entries for the same yogurt with different calorie counts.
• 100+ nutrients tracked. Calories, full macros, fiber, sodium, added sugars, vitamins A through K, magnesium, iron, zinc, potassium, omega-3 balance, saturated fat ratios — the depth Yazio lacks.
• Voice logging. Speak your meal naturally: "two eggs, toast, avocado, and coffee." The AI parses and logs in seconds. Especially useful post-fast when you want to log and eat without phone-tapping.
• Barcode scanner with verified pull. Scan any product, receive verified nutrition data from the Nutrola database rather than user-submitted fields.
• Recipe URL import. Paste any recipe URL and receive a per-serving nutritional breakdown using verified ingredient data.
• Apple Health and Google Fit bidirectional sync. Activity, steps, workouts, weight, and sleep flow into your calorie budget. Nutrition data flows back out to your health dashboard.
• 14 languages. Full localization including Spanish, German, French, Italian, Portuguese, Dutch, Danish, and more — strong fit for European users who find Yazio's localization patchy outside core markets.
• Zero ads on every tier. Including the free tier. No interstitials after logging a meal, no banners on the fasting dashboard.
• €2.50 per month with a free tier. A fraction of Yazio PRO's typical monthly rate, with a free tier that actually works rather than a nag-every-screen trial.

The net effect is that users who choose Nutrola over Yazio get the same combo-app convenience, plus modern AI features, verified nutrition data, full micronutrient depth, and a lower monthly bill. Start free. If you love it, €2.50/month after.

Which Combo App Should You Choose?

Best if you want the exact Yazio combo experience at a better price

Nutrola. Same core value — fasting timer plus calorie tracking in one app — with AI photo logging, verified data, 100+ nutrients, 14 languages, zero ads, and €2.50/month. The honest upgrade path for Yazio users who like the combo but want the nutrition and AI to match.

Best if you are already embedded in Yazio and want to stay

Yazio. The app works. The fasting-calorie integration is real. If the interface and ecosystem already fit your routine and you do not need AI photo logging or micronutrient depth, staying put is a defensible choice. Budget for annual billing to soften the premium pricing.

Best if you want specialist apps for each feature

Simple + Cronometer. Simple is the most polished fasting-only app, and Cronometer is the most accurate calorie tracker in the market. Pairing them costs two subscriptions and splits your data, but you get best-in-class on each side. This is the power-user path, not the convenience path.

Frequently Asked Questions

Does Yazio track both fasting and calories?

Yes. Yazio combines an intermittent fasting timer (12:12, 14:10, 16:8, 18:6, 20:4, custom windows) with a daily calorie counter, macro tracking, barcode scanning, and Apple Health / Google Fit integration. The integration between fasting and calorie data is Yazio's core selling point.

Is Yazio better than MyFitnessPal for intermittent fasting?

For fasting specifically, yes — Yazio has a native fasting timer and MyFitnessPal does not. For calorie tracking alone, MyFitnessPal has a larger food database. Many fasters pair MyFitnessPal with a free fasting app like Zero, though using two apps defeats the integration Yazio provides.

What is the best app for tracking both fasting and calories in 2026?

Nutrola is the best combo option in 2026: it matches Yazio's fasting timer and calorie tracking, adds AI photo logging in under three seconds, a 1.8 million+ verified database, 100+ nutrient tracking, 14 languages, and zero ads, all for €2.50 per month plus a free tier. Yazio remains a solid mid-tier option but lags on AI and nutrition depth.

Can I track a 16:8 fasting window and calorie deficit in the same app?

Yes, in Yazio, Nutrola, and Simple (with limited calorie tracking). Setting a 16:8 window and a daily calorie deficit goal in the same app is the most common combo-tracking setup, and all three apps handle it. Nutrola additionally attaches calorie logs to the current eating window for post-hoc analysis.

Does Yazio have AI food recognition from photos?

No. As of 2026, Yazio's logging flow is barcode and search-based. There is no photo-to-meal AI. Nutrola provides AI photo logging that identifies foods and estimates portions in under three seconds, which matters most when breaking a long fast with a complex meal.

Is Yazio's calorie database accurate?

Yazio's database is large but largely crowdsourced, so duplicate entries and value variance exist. For packaged foods, barcode scanning returns reliable data. For home-cooked meals and restaurant items, verified databases like Nutrola's (1.8M+ reviewed entries) or Cronometer's produce more consistent daily totals.

How much does Yazio cost compared to Nutrola?

Yazio PRO is priced at the premium end of the market, typically billed annually for the best per-month rate. Nutrola is €2.50 per month with a free tier, making it one of the lowest-priced verified combo apps in 2026. The price gap widens further when comparing feature parity, because Nutrola includes AI logging and 100+ nutrients that Yazio does not.

Final Verdict

Yes, Yazio tracks both fasting and calories in one app, and the integration between the two is genuinely useful. That combination is the reason the app has earned its user base and the reason it keeps winning design awards. If you only need a fasting timer and a basic calorie counter in a clean interface, Yazio does the job. The honest critique is not that Yazio fails — it is that the category has moved forward, and Yazio has not kept pace on AI photo logging, verified nutrition data, micronutrient depth, or pricing. Nutrola delivers the same combo experience plus AI in under three seconds, a 1.8 million+ verified database, 100+ nutrients, 14 languages, zero ads, and €2.50 per month with a free tier. If you love the idea of fasting and calorie tracking in one app but want the underlying nutrition to be right, Nutrola is the 2026 upgrade. Start free. If you stay, it is the most affordable way to keep tracking both sides of your health equation without compromise.
