What YAZIO actually does
YAZIO is a food, fitness, and fasting tracker built by YAZIO GmbH, headquartered in Erfurt, Germany. Its free tier is a genuinely usable calorie tracker on its own, with YAZIO PRO layered on top as a paid upgrade rather than a requirement to get basic value.
The core product
The free tier covers manual food logging against a database running into the millions of items, barcode scanning for packaged foods, water and weight tracking, and basic macro breakdowns — enough for most people to start tracking accurately from the first day, since the barcode and photo-based databases mean logging doesn't require manually searching for every item. The app runs on iOS and Android, with a companion web app for browsing recipes and the food database from a desktop.
What's new or notable
YAZIO PRO adds:
- AI-based photo food recognition
- Guided intermittent fasting plans, including 16:8 and 5:2 schedules
- A larger library of trackable recipes
- Integration with fitness wearables such as Fitbit, Garmin, and Apple Watch
- Longer-term trend statistics
- An ad-free interface
YAZIO does not publish one fixed PRO price on a single page; third-party pricing trackers report figures in the range of roughly €29.99 a year (about €2.50 a month) or €4.99–€5.99 billed monthly, with the exact number shifting by country, app store, and whatever promotion is running at the time. The price shown inside the app at checkout is the one that actually applies to a given user.
Who should use YAZIO
Great fit if…
- You want a free calorie tracker that's actually usable — manual logging, barcode scanning, and a multi-million-item database are all free, not locked behind a paywall.
- You want faster day-to-day logging — PRO's AI photo recognition and barcode scanner cut down the time spent searching for foods manually.
- You already do intermittent fasting or want structured fasting plans — PRO's guided 16:8 and 5:2 schedules are built into the same app as your food log.
Skip it if…
- You need individualised dietary or medical advice — YAZIO tracks what you log and turns it into calorie and macro statistics and goal-based suggestions; it is a self-tracking tool, not a dietitian or a source of medical nutrition advice for a specific health condition.
- You want one universal price before committing — PRO's price varies by country, platform, and promotion, so there's no single number that applies to everyone.
- You want wearable sync or AI photo logging without paying — those specific conveniences sit behind PRO; the free tier covers logging basics but not those extras.
Pricing in detail
YAZIO's own site does not display one fixed PRO price; the ranges below come from third-party pricing trackers rather than a single official figure, and should be checked against the in-app price before assuming a number.
| Plan | Price | What's included |
|---|---|---|
| Free | €0 | Manual food logging, multi-million-item food database, barcode scanning, water and weight tracking, basic macro breakdowns |
| YAZIO PRO (yearly) | Roughly €29.99/year (~€2.50/month), per third-party trackers — varies by country and promotion | Everything in Free, plus AI photo food logging, guided intermittent fasting plans, larger recipe library, wearable integrations (Fitbit, Garmin, Apple Watch), longer-term trend statistics, ad-free interface |
| YAZIO PRO (monthly) | Roughly €4.99–€5.99/month, per third-party trackers — varies by country and promotion | Same PRO features as the yearly plan, billed monthly |
Where it falls short
- No fixed PRO price on YAZIO's own site — the numbers that circulate come from third-party pricing trackers rather than one official published figure, so the price at checkout is the only one that can be trusted as current.
- Free tier lacks the faster-logging tools — the free tier is workable for basic tracking but leaves out the AI photo recognition and barcode scanner conveniences that make day-to-day logging quicker.
- Estimates, not medical advice — like any self-logging app, its calorie and nutrition figures are only as accurate as what's entered, scanned, or photographed, and the app does not account for individual medical conditions.
Privacy & data
YAZIO's privacy policy states that all data transmitted between the app and YAZIO's servers, and between YAZIO and third-party providers, is encrypted.
On sharing, the company states health and nutrition data is used solely for its stated purposes and, as a rule, is not visible to third parties, except through opt-in features like the "Buddies" social function; it shares data with service providers such as Google, Apple, and payment processors based on consent or legitimate business interest, and states user data is not combined with other sources for ad targeting without consent — in other words, YAZIO's own policy does not describe selling nutrition data to advertisers.
The company operates under GDPR, with a named data protection officer, and standard rights to access, correct, delete, or export data. On retention, personal data is kept for the period a user is active in the app; deleted accounts have identifying information "definitively and irretrievably deleted," though log files persist for seven days and newsletter records can be kept up to three years for legal-defence purposes.
How we checked this
This review is based on YAZIO's own site (yazio.com) and its published privacy policy (yazio.com/en/privacy), reviewed on 4 September 2026, along with independent third-party pricing trackers used specifically to estimate PRO's current cost since YAZIO does not publish one fixed figure itself. We did not log meals in the app ourselves as part of this review; the description of tracking features and the food database is drawn from YAZIO's own product documentation, not hands-on testing of logging accuracy. Anyone deciding based on price should check the figure shown at checkout in their own app store, since PRO pricing varies by region and promotion.
