Product rating applications are designed to help consumers decipher product labels. Each application uses its own rating system, based on categories chosen by its developers (presence of food additives, nutritional information, organic label, etc.). These applications complement the Nutri-Score, but it should be noted that only the Nutri-Score is based on scientific studies and validated by national and European health authorities.
