An almanac for everyday eating

AI calorie counter,
thoughtfully German.

Snap a meal, scan a barcode, or speak the bite — YAZIO logs it in seconds with macros, micros, and a 4-million-product database. Then bakes in intermittent fasting plans, weekend allowances, and 2,900+ chef-built recipes the rest of your category forgot.

Three movements

From bite to balanced
in under a minute.

The whole point of a calorie counter is that you actually use it. YAZIO's daily flow stays under 60 seconds even for a three-course meal — barcode for packaged, photo for plated, voice for the rest.

I.

Log the bite.

Open the app, tap +, then snap a photo, scan a barcode, or speak the ingredient. YAZIO matches against a 4-million-product database localized for German, US, UK and 18 other markets.

II.

Read the picture.

Your diary updates with calories, macros, fiber, sugar and your protein/carb/fat split. A nutrition score (A–E, Nutri-Score style) flags what to keep and what to swap on tomorrow's grocery list.

III.

Adjust the plan.

Weekend Calories lets you eat more on chosen days without breaking the plan. Or pair tracking with a 16:8 or 5:2 fasting window, with the timer and ketosis hints baked in.

No. VII · The weekday/weekend pact

Weekend Calories: eat more on Saturday, on purpose.

The honest truth most calorie apps avoid: nobody stays at 1,800 kcal seven days a week. YAZIO's Weekend Calories feature lets you reallocate budget from quieter weekdays to Friday dinner or Sunday brunch. Same weekly total, far less guilt — and it's bundled with full 16:8 and 5:2 fasting plans, a ketosis indicator and a fasting timer that doesn't shame you when you break early.

This is the feature that turned YAZIO from "another calorie tracker" into the default fasting-plus-nutrition app for German-speaking Europe — and a credible alternative everywhere else.

Who reaches for the almanac

Built for the four
kinds of eaters.

Not everyone counting calories wants the same outcome. YAZIO is wide enough to cover all four — even the eaters who hate the word "diet."

α

Steady losers

A real deficit you can hold for months, not weeks. Weekend Calories means weddings don't undo a quarter of work.

β

Fasting practitioners

16:8, 14:10, 5:2 with a clean timer, ketosis indicator and meal-window logging fused into the food diary.

γ

Macro nerds

Protein, fiber and added-sugar targets per day; full micro view if you turn it on. Granular without becoming a spreadsheet.

δ

Recipe-led cooks

2,900+ chef-built recipes filterable by low-carb, vegan, keto and high-protein, with auto-generated grocery lists.

The cabinet, drawer by drawer

Every drawer of the
apothecary, opened.

A calorie counter you'll keep opening means six things working together. Here are YAZIO's six, the order they arrived, and what they actually do.

No. 01 · the headliner

AI photo logging.

Snap a plate, get a parsed list of foods with portion estimates. Honest disclosure: results are roughly two-thirds accurate on first pass — you'll often re-prompt or correct one ingredient. Faster than typing, slower than a barcode.

No. 02

4M-product database.

Localized per market — Brötchen, Quark, Wurst varieties native in DE; supermarket SKUs in US/UK.

No. 03

Barcode scanner.

The fastest log in the app. Aim, beep, done — works on packaged goods worldwide, including most private-label SKUs.

No. 04 · pro moat

Fasting plans.

16:8, 14:10, 18:6, 5:2 — with timer, ketosis indicator and the cleanest fasting UX in the category. Free version covers the basics.

No. 05

2,900+ recipes.

Weekly updates, low-carb / vegan / keto / high-protein filters, auto grocery list, step-by-step cooking mode.

No. 06 · ecosystem

Health-platform sync.

Two-way sync with Apple Health and Google Fit, plus Fitbit and Garmin Connect. Steps and workouts flow in; calories burned flow back out to your tracker without manual entry.

Three honest reads
(one isn't a rave).

We include one mixed review for credibility. Calorie apps are too personal for a wall of five-stars to mean anything.

★★★★★
"The design is so much better than apps like MyFitnessPal that look so plain. It conveniently connects to my Apple Watch, tracks water, gives recipes, runs challenges, and does intermittent fasting — best calorie counter I've used."
Maya R. · App Store review · US
★★★★★
"Good UI, but for €84/year it's twice the price of other apps. The AI gets about two-thirds of ingredients right, so I keep rewriting. Recipes are also a bit basic for paid."

"I've been trying to lose weight for years. With YAZIO I've finally done it — 22 pounds in three months. The synchronization of steps and activities is what keeps me going."

Erfurt, 2009 — Today

A nutrition app
built like a pharmacy.

YAZIO is German engineering applied to nutrition: localized, methodical, and unafraid to ship features the loud Silicon Valley apps skipped.

YAZIO started in 2009 as 6colors, a small Erfurt studio run by Florian Weißenstein and Sebastian Weber. It became YAZIO in 2014 — same founders, same town, sharper focus: build the most localized nutrition app possible for the German, Austrian and Swiss markets, and let the international expansion follow when the product earned it.

That bet worked. By 2024 the app had crossed 100M registered users and 1M paying subscribers in 100+ countries and 20 languages. In late 2023, French consumer-goods group SEB took a majority stake — fuel for international growth without uprooting the team from Erfurt. Florian and Sebastian still lead the company. The team is at ~148 people, 32 nationalities. The full company facts are on the official YAZIO website if you want to dig in.

The honest tradeoff: YAZIO is brilliant inside its strengths and merely OK outside them. The US/UK food database is solid but smaller than MyFitnessPal's. The AI photo recognition shipped in 2023 and still gets about two-thirds of ingredients right on the first try — you'll often re-prompt or correct one. There's no offline mode, which matters for travelers in low-signal zones. Pro pricing varies by region and has crept up; users report up to €84/year, double some competitors. We say all of this on purpose: if you log mostly packaged goods, MyFitnessPal's database may serve you better; if you need 82-nutrient micro tracking for a medical reason, Cronometer is the call.

If you want the cleanest fasting UX in the category, native German-market localization, a usable free tier, and a calorie counter that respects that you sometimes eat cake on a Saturday — that's the YAZIO bet, and it's been the right one for 100M people.

Asked & answered

Frequently asked,
honestly answered.

The questions we'd want answered before downloading a calorie counter — including the ones YAZIO loses on.

Is YAZIO actually free to use?
Yes — the free tier is fully usable on its own. You get calorie and macro tracking, the food diary, the barcode scanner, basic recipes, water and activity logging, body-measurement tracking and basic intermittent-fasting timing. Pro unlocks deeper analysis, advanced fasting plans, AI photo logging in full, the entire recipe library and an ad-free experience. The free version is good enough that millions of users never upgrade.
How accurate is the AI food photo recognition?
Honest answer: roughly two-thirds correct on the first attempt, per user reports and our own testing. It's reliably great on single foods and basic plates, and weaker on mixed dishes, sauces and dim lighting. Treat it as a smart starting point you confirm, not magic. Barcode scanning remains the fastest and most accurate logging method in YAZIO.
How does Weekend Calories actually work?
You tell YAZIO which days are your "weekend" (Sat/Sun by default, configurable). The app reallocates some of your weekly calorie budget from chosen weekdays onto those days. Same weekly total, more flexibility around restaurants and social meals. It's the feature regular calorie counting apps don't have — and the reason many people stop falling off plan on Saturday night.
Which intermittent fasting plans are supported?
All the common ones — 16:8, 14:10, 18:6, 20:4 and 5:2 — with a clean fasting timer, ketosis indicator, and helpful guidance on autophagy and energy use. Fasting windows sync with the food diary so eating and fasting hours stay consistent. Basic fasting is in the free tier; advanced plans are part of Pro.
Does YAZIO sync with Apple Health, Google Fit and wearables?
Yes. Two-way sync with Apple Health and Google Fit comes built in, plus Fitbit and Garmin Connect. Steps, workouts and calories burned flow into YAZIO; logged nutrition flows back out. Apple Watch users get a native app and complications. Note that some users on Garmin have reported sporadic sync delays — usually a logout/login or reconnect resolves it.
How much is YAZIO Pro?
Pricing varies by country and promotional offer. As a guide, yearly Pro has been reported between roughly €40 and €84 depending on region and discount, with monthly pricing also available. That puts it in line with MyFitnessPal Premium at the lower end and notably above Lose It! at the higher end. Always check current pricing in your local App Store or Google Play before subscribing.
Does YAZIO work offline?
This is one of YAZIO's honest weaknesses: full functionality requires an internet connection. The barcode scanner, AI photo logging and database lookups don't work in airplane mode or low-signal areas. If you log meals while traveling in remote regions, Lose It! is better in this single dimension. For everyday use in connected environments, you won't notice.
Is YAZIO good for ketogenic, vegan or low-carb diets?
Yes — the recipe library has dedicated filters for keto, low-carb, vegetarian, vegan, gluten-free, pescatarian and high-protein, and the macro targets can be set to dial in your preferred ratio. The keto plan pairs naturally with intermittent fasting and includes ketosis-window guidance.
Who built YAZIO and where is the company based?
YAZIO GmbH is headquartered in Erfurt, Germany, at Kartäuserstr. 13a. It was founded in 2009 by Florian Weißenstein and Sebastian Weber (originally as 6colors GmbH, renamed YAZIO in 2014). The team is around 148 people from 32 nationalities. In late 2023, French consumer-goods group SEB acquired a majority stake to support international expansion. The founders remain in active leadership roles.
