Yuka is a French app launched in 2017 by Benoit Martin, Francois Martin and Julie Chapon. It is based in Paris.
Users scan the barcode of a food or cosmetic product and get a score out of 100. Food scores look at nutrition, additives and whether the product is organic. Cosmetic scores look at each ingredient and its known risks. When a product scores badly, Yuka suggests similar products that score better.
Yuka takes no money from brands and shows no ads. The app is free, and a paid membership adds offline mode, search and a few extra features.
