Nouri vs YAZIO: Which Calorie Tracker Fits You in 2026?

YAZIO bets on breadth: a free food diary with a stated four-million-item database, fasting timers, and recipes, on iPhone and Android. Nouri bets on speed and insight: type, say, photograph, or tell Siri what you ate, and a weekly Nouri Report tells you what to change, for $39.99/year. We make Nouri; every YAZIO fact below is cited with the date checked.

Nouri: log in seconds, then get a report that tells you what to change

Nouri wins on:

• Speed: type what you ate like a note ("two eggs, toast with butter, oat milk latte"), say it, or snap a photo. A photo becomes a sentence first, so you see what Nouri read before anything is counted
• Estimates you can check: calories, protein, carbs, and fat item by item with visible reasoning, plus "large portion" or "cooked in oil" and a recalculate when something looks off
• The best Siri logging of any calorie tracking app: say "Hey Siri, track food in Nouri" from the lock screen, answer in one sentence, and the calories and macros card appears right away with what you have left for the day, without opening the app
• Nouri writes your nutrition totals to Apple Health and brings in calories burned, workouts, and steps, so what you eat sits next to what you burn
• A Health Score on every meal, Nouri Coach for questions about your own eating, and smart reminders for busy days
• One subscription, no tiers: photo logging, Coach, and a Nouri Report every Sunday evening for weeks with 4 or more logged days

Weaknesses:

• iPhone only, so Android users should look elsewhere
• No barcode scanner: packaged food is typed, said, or photographed
• No free tier beyond the 3-day free trial
• No recipe library or fasting timers, micronutrients are limited to fiber, sugar, sodium, and a vitamin scorecard, and targets come from a published formula at onboarding

Best for: anyone who wants logging to take seconds and wants to learn from it every week: busy people, home cooks, restaurant regulars, and everyone who quit a tracker before.

Pricing: $9.99/month or $39.99/year (USD), with a 3-day free trial on the yearly plan (try Nouri free)

YAZIO: the free diary with fasting and recipes bundled in

Everything below comes from YAZIO's own published materials, checked September 27, 2026.

YAZIO wins on:

• A genuine free tier: food diary, calorie and macro goals, barcode scanner, water tracker, and the 16:8 fasting plan, with instant access and no signup required per its store listing
• A stated database of over four million items, plus custom foods, meals, and recipes
• Fasting: about 20 plans, and its tutorial states "16:8 is available in the free version, all other fasting trackers can only be used in Yazio Pro"
• Breadth: more than 3,000 recipes created and tested by its nutrition experts (2,900+ on its App Store listing), meal planning, grocery lists, its own food rating system, and mood and symptom tracking
• Android and iPhone, a standalone Apple Watch app, and free Apple Health and Health Connect sync
• Scale: it states it is "Trusted by 100M and counting"

Weaknesses:

• No web version. Its website handles accounts and purchases only
• Pricing is not published on its own site. The App Store shows PRO purchases from $11.90 to $47.90 with duplicate product names; Google Play lists $6.99 to $299.99 per item. Its help center states "A monthly payment is not possible," and the 7-day trial is website-only: "it is not possible to subscribe to it directly in the app"
• A lot sits behind PRO: AI photo tracking, recipes, weekly and monthly analyses, micronutrient detail, most fasting plans, manual step entry, and Fitbit, Garmin, Samsung Health, and Polar integrations
• Its free tier carries ads

Best for: people who want to start free, use Android, or want fasting timers, recipes, and meal planning in the same app as their food diary.

Pricing: free tier with ads; PRO via in-app purchase, with no single price published on its site. Check the current offer in-app (yazio.com)

The real difference: YAZIO adds features, Nouri removes friction

YAZIO is trying to be the whole health app: diary, fasting, recipes, meal plans, mood, water. But every feature depends on a meal actually getting logged, and in a database-first diary a normal dinner still means searching, picking an entry, and guessing a portion, item by item. Nouri attacks that step, so the meals that usually go missing, the Tuesday dinner, the drive-thru, the snack at your desk, actually get logged. A longer feature list does not fix friction, which is the argument in The Most Frictionless Calorie Tracker in the World.

Both apps read meal photos. In YAZIO, AI photo tracking moved from free to PRO, per its own help center. In Nouri, photo is one of four equal ways to log, all in one plan, and you can correct "rice" to "fried rice" before a single calorie is counted.

Nouri Reports: most calorie apps give you numbers, Nouri gives you answers

YAZIO lists weekly and monthly analyses among its PRO features. A Nouri Report answers a different question: what actually happened this week and what to do about it.

When you get them: log on 3 days within your first week and Nouri builds your first personal report. After that, a fresh report arrives every Sunday evening for any week with 4 or more logged days.

What is inside:

• Health Score with "Why this score?", so you see exactly what drove it
• The numbers: average calories, protein, carbs, and fat against your targets, with progress bars
• Days on target, judged by your goal, whether that is losing, maintaining, or gaining, not by a generic number
• Wins, slips, and one clear focus for the week ahead
• Your MVP food of the week, protein equivalents, and a personality badge for your eating style
• Apple Health: calories burned against calories eaten, plus your workouts

Reports live under Progress, then Reports, and are part of Nouri Premium.

What I learned trying to log a homemade dinner

My mother's arroz con pollo is not in any food database. It is a recipe that exists in one kitchen. In a database-first app, logging it means building a custom recipe from a dozen ingredients, which I did exactly once, or accepting a stranger's entry with the same name.

In Nouri the log is "mom's arroz con pollo, medium plate, chicken thigh and rice, cooked in oil." It comes back itemized in seconds, with the reasoning visible, and if the plate was bigger I add "large portion" and recalculate. It is not more precise than a carefully built custom recipe. It is far more likely to actually happen on a Tuesday, and a log that happens beats a log that is precise, as we argue in Why Calorie Tracking Apps Are Inaccurate. Then on Sunday evening the report shows my Health Score and why, the days I hit my goal, the slip that cost me, and one thing to focus on next. Seconds to log and one clear answer a week is what keeps people tracking long enough to see results.

How to choose

Pick Nouri if you are on iPhone and want the fastest logging available, cook food no database contains, want Siri from the lock screen, or want a weekly report that tells you what to change. Pick YAZIO if you want a free tier, use Android, or want fasting timers, recipes, and meal planning bundled with your food diary. Either way, use the test from Best Calorie Tracker App in 2026: log everything for two weeks, then count the gaps.

FAQ

Is Nouri or YAZIO better?

For fast logging and real insight, Nouri: it logs a meal in seconds, shows the reasoning behind every estimate, and turns your week into a Nouri Report with one clear focus. YAZIO is the better fit if you want a free tier, use Android, or want fasting timers and a recipe library in the same app.

What makes Nouri different from other calorie trackers?

Speed and answers. You log by typing, voice, photo, or Siri, and the AI returns calories and macros instantly with its reasoning visible. Then Nouri Reports tell you what drove your Health Score and what to change next week.

What is a Nouri Report?

A personal weekly report built from your own logs: your Health Score with "Why this score?", macros against targets, days on target judged by your goal, wins, slips, and one clear focus. Your first one arrives after 3 logged days in your first week, then every Sunday evening when you log 4 or more days.

Is Nouri worth it?

If you have quit a tracker before because logging took too long, yes. At $39.99/year you get every way to log, Nouri Coach, and weekly Nouri Reports in one plan, and the 3-day free trial is enough to feel the difference.

Is YAZIO free?

Yes, there is a free version with ads, which includes the food diary, calorie and macro goals, barcode scanning, water tracking, and the 16:8 fasting plan. Its AI photo tracking, recipes, weekly and monthly analyses, most fasting plans, and micronutrient detail require PRO.

How much does YAZIO PRO cost?

YAZIO does not publish a price on its own website. Its App Store listing shows PRO in-app purchases from $11.90 to $47.90, and Google Play states $6.99 to $299.99 per item, so check the offer in your own app. Nouri is $9.99/month or $39.99/year.

Is YAZIO's AI photo tracking free?

Not anymore. Its help center states the feature "was initially available to all users for free and is now part of Yazio Pro." In Nouri, photo logging is part of the single plan.

Does YAZIO have a web version?

No. Its help center states: "We currently do not offer a web version or versions for Windows or Mac. Yazio can only be used on your Android or iOS device."

Which app is better for intermittent fasting?

YAZIO. It publishes around 20 fasting trackers, with 16:8 free and the rest in PRO. Nouri has no fasting timer, so if fasting windows are central to your plan, YAZIO is the pick.

Which is better for home cooking?

Nouri, because "mom's arroz con pollo, medium plate" is a complete log, itemized with its reasoning in seconds; YAZIO's answer is a custom recipe builder that pays off if you cook the same dishes often. Nouri also lets you log by voice: say "Hey Siri, track food in Nouri" from the lock screen, answer in one sentence, and the calories and macros card appears right away with what you have left for the day, without opening the app.

Does Nouri work on Android?

No, Nouri is iPhone (iOS only). YAZIO covers both iPhone and Android, so Android users should pick YAZIO in this comparison.

Which app is more accurate?

Nouri now publishes one: in our 100-meal accuracy benchmark, it averaged 92.1 out of 100 against USDA and official restaurant data. We have not tested YAZIO, and every tracker inherits the same label and portion error, as we document in Why Calorie Tracking Apps Are Inaccurate. YAZIO's own documentation says its AI photo feature "only provides a rough estimate," which is the honest position for any estimate-based tracker, ours included. Nouri adds transparency: every estimate shows its reasoning item by item, so you can fix a wrong portion in a tap.

Bottom line

YAZIO is a broad, free-to-start diary with fasting and recipes, and the right call if you want a free tier or Android, at the cost of ads, a heavy PRO paywall, and no published price. Nouri is built for the part that decides whether tracking works at all: fast logging, visible reasoning, and a weekly Nouri Report that tells you what to change, at $39.99/year. Set an honest target from Calorie Counting 101 or our free TDEE calculator, then start the 3-day free trial.
