Yazio's app is localized in 20 languages, including Dutch, Polish, Swedish, Danish and Turkish, and the new Performance Marketing Manager is asked for French or Dutch. But www.yazio.com/nl, /pl, /sv, /da, /tr and /ja all serve the English homepage with an /en canonical, and every call to action on /nl opens the English web onboarding. Paid and organic traffic from those countries meets a product in its language in the store and an English website in the browser.

Why it works
Start with Dutch: translate the homepage, the four calculators and the web onboarding into Dutch, publish them at /nl with hreflang (nl, nl-BE) and an x-default, and route Dutch and Flemish campaigns there. Measure onboarding completion and trial starts against the English path, then repeat for the next two languages by traffic. Have native reviewers and legal check all health-related wording in each language before launch.
Visitors complete sign-up flows far more often in their own language, and campaigns in those countries can then use web onboarding as the English, German and French markets already do.

- Your websiteLanguages: the site's language switcher and hreflang tags cover six languages (de, en, es, fr, it, pt) with no x-default. www.yazio.com/nl, /pl, /sv, /da, /tr and /ja all return the English homepage (html lang "en", canonical /en) with a 200 status, and every link on /nl, including the onboarding calls to action, points to /en.Source
- App StoreThe iOS app is localized in 20 languages, including Dutch, Danish, Finnish, Norwegian, Swedish, Polish, Czech, Hungarian, Greek, Turkish, Russian, Japanese, Korean and Chinese. The Dutch store listing ("Yazio: calorieënteller") has 4.6 stars from 28,189 ratings; the US listing ("AI Calorie Tracker by Yazio") has 4.7 stars from 51,393 ratings and was updated October 21, 2026.Source
- HiringPerformance Marketing Manager (remote in Germany, Spain, Portugal or the UK, posted October 7, 2026): runs user acquisition "across DSPs (e.g., Appier, Liftoff, Unity), paid social and search (e.g., Meta, Google Ads, ASA)", gives "actionable insights to the creative team", must "spot measurement gaps and work with product, web and analytics teams to improve tracking and attribution", and "Nice to have: ... fluency in French or Dutch". Every post says Yazio has "millions of users in over 150 countries".Source
- Your websiteHomepage (checked October 22, 2026): page title "Healthy Weight Loss & Eating: Lose Weight Fast with Yazio" and description "...you'll lose weight fast and feel great! 100% free."; the French and German pages say the same ("perdre son poids rapidement", "100% gratuit"; "schnell Gewicht verlieren", "100% kostenlos"). The page itself leads with "Build healthy habits you'll love to keep", goals from losing weight to building muscle and eating mindfully, AI photo tracking, fasting timers, "3,000+ recipes" and "Trusted by 100M and counting". Every call to action opens a web onboarding flow (/en/app/onboarding/welcome?...&trial=1) whose page title is "Upgrade to Yazio Pro and reach your nutrition goals."; the footer has "Cancel subscription". Four calculators: BMI, ideal weight, daily calorie intake and calories burned. No recipe section on the site (/en/recipes returns 404).Source
