What's New in Yuko Scanner for Food Safety

5.0.6

November 12, 2026

Clearer results and more additive names recognized. • Sugars, salt, fats and allergens now appear by name, without Yuko's internal codes. • More additive names are recognized on labels, including US color names such as Yellow 5 and Blue 1, and glaze names such as confectioner's glaze (shellac, E904). • Label matching is more accurate, with fewer mix-ups between similar names. • Two new health conditions: gout and insulin resistance, with their sources. • New Updates area: see Yuko's in-app events and, if you like, turn on Events in Settings to get a notification when a new one starts. • History now keeps up to 50 label scans instead of 10, each with its photo. • Notification fixes: if you've already purchased, you no longer get offer reminders. Thanks for scanning with Yuko!

Response from developer

En japonais, yūkō (有効) veut dire « efficace ». C'est exactement ce que nous voulons que Yuko soit pour vous au moment de choisir un produit. Yuko est conçu pour fonctionner partout dans le monde : l'application est disponible en 40 langues et lit les listes d'ingrédients imprimées sur les emballages dans de nombreuses langues. Il suffit de photographier l'étiquette, sans que le produit ait besoin de figurer dans une base de données, et chaque additif détecté vous est expliqué. Vous pouvez aussi créer un profil de santé, pour vous et pour chaque membre de votre foyer, parmi 17 problèmes de santé : diabète, hypertension, maladie cœliaque, intolérance au lactose, allergies, migraine, grossesse et d'autres. Yuko s'appuie alors sur 137 règles d'alerte pour vous signaler les ingrédients à surveiller selon votre profil. Ces informations vous aident à lire les étiquettes et ne remplacent pas l'avis d'un professionnel de santé. Nous sommes désolés que votre première impression ait été mauvaise. Si vous voulez bien nous dire ce qui n'a pas fonctionné, écrivez-nous à edaburakguner@gmail.com.

Great Guide

This is so useful for the personal information that you need for your particular diet restrictions or just to know how leery we should be about the ingredients that make up what we consume. I look forward to using this site. It’s fun and informative.

Response from developer

Thank you so much for the kind words! Knowing what is actually in packaged food should not feel like guesswork, and we are really glad Yuko makes the ingredient side clearer for you. Two things that may help with your diet restrictions: in Settings, "Allergen Management" lets you pick the additives you need to avoid, and they are called out on every scan result. Under "Your Health Profile" you can also set conditions such as diabetes, celiac disease or pregnancy, and the warnings adjust to them. And whenever a rating is unclear, tap the "i" button on a result and open "How We Score" for a short guide to the ratings and the four additive risk levels. If anything ever looks off, we would love to hear from you at edaburakguner@gmail.com. Happy scanning!

Take Note

This is not the preferred food tracking app know as YUKA not this one YUKO. This app is totally useless and unlike YUKA you have to pay for the use of the app.

Response from developer

Thanks for writing, and sorry for the mix-up. Yuko is a different app, made by a different company. We are not affiliated with the other one and not a version of it. Here is what Yuko does, and where it is strongest. You do not need the product to be in a barcode database. Point the camera at the printed ingredients list and Yuko reads the text on your device, then checks it against the additive catalogue built into the app. A barcode lookup can only find what someone has already typed into a database; the ingredients are printed on the packet in your hand. So imported goods, small local brands, store brands, something you carried home from a trip - all of it can be checked, with no signal and no database entry. That catalogue is 386 entries: 340 E-numbers plus 46 ingredients written out in words, including gluten, milk, eggs, soy, peanuts, sesame, palm oil, partially hydrogenated oil, high-fructose corn syrup and caffeine. Each entry carries its name in 34 languages and the other spellings it gets printed under, so "E102" and "tartrazine" land on the same entry. Labels are read in English, and in Turkish, Spanish, German, French or Dutch when your device is set to one of those. Scanning the barcode works too. Yuko looks it up in Open Food Facts, the community food database, for the product name and photo, nutrition per 100 g, and the Nutri-Score, NOVA and Eco-Score. You can also build a profile from 17 conditions - celiac disease, lactose intolerance, pregnancy and others - with 137 warning rules behind them, and keep a separate profile for each person in your household, so one scan says what matters for each of them. The whole catalogue is browsable in the Additives tab without scanning anything. Risk levels come from EFSA, WHO, FAO and the Turkish Food Codex, all four listed in Settings, About, beside a health disclaimer that says this is general information and not medical advice. Two limits, honestly: the label scan reports what it finds in the ingredients list, so it covers additives and ingredients rather than calories, and if the light is poor or the print too small it tells you the label could not be read instead of producing a verdict anyway. On cost, since that part of your review is fair: Yuko is free to download and the first 3 scans are free - the subscription screen has a close button in the top corner. After that the scanner runs on Pro: $6.99 a week with a 3-day free trial, $19.99 a year, or $49.99 once for lifetime access. Everything above is included in all three. An update is with Apple right now that rebuilds the barcode side: score breakdowns point by point, the full nutrition table per 100 g or per serving, ingredients with allergens highlighted, packaging and recycling, origins and photos. If you give it another look and something is wrong, Settings, Contact Support reaches us. The product that scanned badly is the most useful thing you can send.

No response from “Contact support”

Very poor app. The information is not user friendly and no one responded to me. Do not use.

Response from developer

I'm sorry. You reached out for help and didn't hear back, and that's on us. Our support inbox fell behind, and we've been working through it and replying to the messages that were waiting. If you wrote in, please check your inbox (and spam folder, just in case), or write again at edaburakguner@gmail.com. I'd also really like to know what felt unclear. One thing that may help: on any scan result, tap the "i" button at the top, then "How We Score" for a short guide to what the ratings and the four additive risk levels mean. If it still feels confusing, tell me which part so I can look at making it clearer. Burak

Peace of mind

An easy way to decipher all the unknown ingredients in a favorite product

Response from developer

Thank you, AM3324 — "peace of mind" is exactly what we're going for. One small tip in case it's useful: besides the barcode, you can point the camera at the ingredients list on the back of any pack, and Yuko reads the label itself and grades the additives it finds, so it works even for products that aren't in any database. If anything ever looks off, write to us at edaburakguner@gmail.com; we read every message.
