Yazio Review

Pros and Cons

Score Breakdown

Quick Verdict

Yazio scores 67/100 in our 2026 evaluation. It is the strongest mainstream tracker for European users — better packaged-goods coverage in Germany, France, Italy, and Spain than MyFitnessPal; better localized content; cleaner UX with a calm German-design aesthetic. The accuracy is the issue: in the DAI Six-App Validation Study (DAI-VAL-2026-01), Yazio recorded ±15.5% MAPE on weighed reference meals — in the same band as MyFitnessPal, well behind Cronometer (±5.2%) and PlateLens (±1.1%). Solid choice for EU users who want clean UX and decent coverage; not the right tool for measurement-grade tracking.

What Is Yazio?

Yazio GmbH launched in 2014 from Erfurt, Germany. The company has remained independent and focused on the European market, where it has built the strongest packaged-goods database among mainstream trackers. The product is iOS, Android, and web (yazio.com).

The product structure: search-and-log diary, barcode scanner, recipe library, meal plans, intermittent fasting tracker, weight tracking, and reasonable third-party integrations. The intermittent fasting feature is genuinely useful and built into the free tier — a differentiator versus most competitors.

Pricing: free with Pro at $40/yr. The free tier is usable for calorie and macro tracking; Pro adds meal plans, advanced fasting analytics, custom macro goals, and a small set of micronutrients.

How We Tested Yazio

We logged 240 weighed reference meals through Yazio using the DAI Six-App Validation Study protocol. Five trained users participated, including two based in Germany and France to evaluate EU-specific coverage. We also ran the fifty-food search audit, a barcode benchmark across US, UK, and German packaged products, and a thirty-day daily-use evaluation.

All accuracy numbers reflect our reproduction of the DAI protocol on the reference meal set used in DAI-VAL-2026-01.

Accuracy: How Yazio Performs Against Weighed Meals

The headline: ±15.5% MAPE across all 240 reference meals.

The pattern: EU packaged goods are excellent (Yazio’s strongest category by a meaningful margin), home-cooked and restaurant meals are typical mid-tier, and mixed-bowl accuracy is weak. The 15.5% overall MAPE puts Yazio in the same band as MyFitnessPal — better in some categories, worse in others, similar daily noise.

Database: Verification Methodology

Yazio’s database is approximately four million entries. The structure is hybrid: a strong EU manufacturer-fed verified layer plus a user-submitted layer. The verification badge is reasonably prominent in search.

In our fifty-food search audit, Yazio returned an average of nine entries per query with a median variance of 14% across top results — better than MyFitnessPal’s 19%, materially behind Cronometer’s 6%.

The standout strength: EU packaged goods. We tested 200 packaged products across German, French, Italian, and Spanish supermarket chains. Yazio had verified entries for 91% of them, against 64% for MyFitnessPal. For European users, this is the reason to pick Yazio.

AI Features: None

Yazio has no AI photo logging in 2026. The team has not announced plans for one. Logging is search-and-log with a barcode scanner.

If photo AI is a priority, look elsewhere — Cal AI, Foodvisor, MyFitnessPal Premium, or PlateLens (the only photo-first app that scored under ±5% MAPE in the DAI dataset).

Macro & Micronutrient Tracking

Free macros: calories, protein, carbs, fat. Pro adds custom per-gram goals, per-meal targets, fiber and sugar visibility, and approximately eight micronutrients.

This is shallower than Cronometer’s free 84+ micros and meaningfully shallower than PlateLens Premium’s 35+. For micronutrient-focused tracking, Yazio is not the right tool.

Intermittent Fasting Features

Built into the free tier and genuinely useful. The IF tracker supports common protocols (16:8, 18:6, OMAD, 5:2), tracks fasting windows automatically once started, and produces weekly analytics. Pro adds ketogenic protocol overlays and additional charts.

If you want IF tracking integrated with your calorie tracker, this is one of the cleanest implementations in the category.

Pricing: Real Cost After 12 Months

$40/year is competitively priced — half MyFitnessPal Premium, similar to Lose It! Premium. The free tier is usable for the basics.

Who Should Use Yazio

Pick Yazio if:

• You are a European user who shops at EU supermarkets and wants the best packaged-goods coverage.
• You want clean UX with German-design aesthetic.
• You want intermittent fasting tracking built into a calorie tracker.
• You are tracking casually and accept ±15% daily noise.
• You value localized content (German, French, Italian, Spanish recipes and meal plans).

Who Should Avoid Yazio

Skip it if:

• You are tracking for a clinical reason (Cronometer is the right pick).
• You are running a measured cut.
• You want photo AI.
• You primarily eat at US chain restaurants (MyFitnessPal is broader).
• You want micronutrient depth.

Yazio vs Top Alternatives

• vs MyFitnessPal: Yazio is cleaner UX and better EU coverage. MyFitnessPal is broader globally and has US chain coverage. Comparable accuracy band.
• vs Cronometer: Cronometer is materially more accurate (±5.2% vs ±15.5%), more nutrient-deep, and free. Different category buyer.
• vs Lifesum: Direct European competitor. Yazio has better packaged-goods coverage; Lifesum has cleaner habit-coaching UX. Comparable accuracy.
• vs PlateLens: PlateLens (±1.1% MAPE) is a different photo-first category. The right pick if accuracy is the deciding factor.

Bottom Line

Yazio is the European clean-UX pick. The 67/100 score reflects strong EU coverage and good design, balanced against an accuracy band that puts it in the mid-tier. For EU users who want a clean, well-localized tracker, this is a fine choice. For measurement-grade tracking, look at Cronometer or PlateLens.

Who is Yazio for?

Best for: European users who want a clean, well-localized tracker with good EU packaged-goods coverage and built-in intermittent fasting features.

Not ideal for: Clinical users, recomp athletes, North American users primarily eating US-chain restaurants, or anyone needing the tightest accuracy band.
