Yuka is a free mobile app that lets you scan the barcode of a food or cosmetic product and instantly see a health rating on a scale of 0 to 100. Launched in France in 2017, it now covers more than 4 million food products and 2 million cosmetic products across multiple countries. The idea is simple: point your phone at a product in the store, and Yuka tells you whether it’s a good, mediocre, or poor choice for your health.
How Scanning and Scoring Work
When you scan a barcode, Yuka pulls up the product’s ingredient list and nutritional data, then assigns a color-coded score. Green means good, orange means mediocre, and red means poor. For food products, the score draws heavily on a product’s nutritional profile, factoring in things like sugar, salt, saturated fat, calories, fiber, and protein content. The presence of additives also matters. Yuka flags specific additives it considers risky and lowers the score accordingly. Whether a product carries an organic certification can bump the score up slightly as well.
For cosmetics and personal care products, the scoring focuses almost entirely on ingredients. Yuka evaluates each ingredient for potential health concerns, pulling from databases on endocrine disruptors, allergens, and irritants. The app then recommends alternatives if your product scores poorly, suggesting similar items with better ingredient profiles.
Who Built It and Why
Yuka was co-founded by Benoit Martin, François Martin, and Julie Chapon. The trio started development in 2016 and officially launched the app the following year. Their stated goal is straightforward: give people access to more transparent information so they can make better choices for their health. The app started in France, where it became enormously popular, and has since expanded to the United States, Canada, the United Kingdom, Germany, Italy, Spain, Switzerland, and Luxembourg.
How Yuka Makes Money Without Ads
One of the things that sets Yuka apart from many product-rating platforms is its funding model. The app carries no advertisements at all. Brands cannot pay Yuka to promote their products or influence their scores. Revenue comes entirely from users, not manufacturers.
In 2024, premium subscriptions generated about $7.17 million, with smaller amounts coming from book and calendar sales (roughly $138,000) and services ($58,000). This structure is intentional. The company positions its independence from the food and cosmetics industries as central to its credibility. If brands could pay for better scores or ad placement, the entire premise of the app would collapse.
Free vs. Premium Features
The free version of Yuka gives you barcode scanning, health scores, and product recommendations. That’s enough for most casual users who want to check a product while shopping. The premium membership adds several convenience features:
- Offline mode: Scan items even without a cell signal, useful in stores with poor reception.
- Search bar: Look up any product by name without needing to physically scan it.
- Food preference alerts: Set custom notifications for ingredients you want to avoid, like palm oil, gluten, or lactose. You can also filter for vegetarian products.
- Unlimited scan history: Access every product you’ve scanned over the past year.
Privacy and Data Handling
Yuka states it has not sold or shared personal information to third parties for business or commercial purposes. The app does share some data with service providers who help run its infrastructure, but these third parties are bound by contracts restricting how they can use that information. Yuka may also share de-identified (non-personal) data for approved research projects, subject to ethics oversight. For an app that collects information about your dietary habits and product preferences, this is a meaningful distinction. Your scan history is not being packaged and sold to health insurance companies or advertisers.
Legal Battles With the Food Industry
Yuka’s scoring system has not gone unchallenged. In 2021, a major French meat industry trade group sued Yuka for defamation and unfair commercial practices. The group argued that Yuka was unfairly penalizing its members’ products by giving low scores based on the presence of nitrites and nitrates, preservatives commonly used in processed meats. A lower court in Paris initially sided with the industry. But an appellate court reversed that decision, ruling that Yuka functions as a consumer tool designed to help people make better health choices. The case became a significant legal precedent for independent product-rating platforms, essentially affirming that an app can flag ingredients it considers problematic without that constituting defamation.
Limitations Worth Knowing
Yuka is a useful starting point, but it has real limitations. The scoring system is algorithm-driven, meaning it applies the same formula to every product regardless of context. A food that scores poorly because of its fat content might be perfectly fine for someone on a high-fat diet. Conversely, a product with a high score might still not fit your specific nutritional needs. The app treats all users the same and doesn’t account for individual health conditions, medications, or dietary goals.
The cosmetics scoring can also be more conservative than some toxicologists would agree with. Yuka may flag an ingredient as risky based on studies that used concentrations far higher than what you’d encounter in a face cream. This doesn’t mean the warnings are wrong, but the dose matters, and the app doesn’t always communicate that nuance.
Product coverage also varies by country. While the database is large, you’ll occasionally scan something and find no data available, especially for smaller or regional brands. Users can contribute missing product information manually, which helps the database grow but also introduces the possibility of errors from user-submitted data.
