The Yuka app is an independent tool for checking food and cosmetic ingredients, known for its strict, ad-free rating system based on nutritional quality, additives, and organic standards. However, experts suggest using it as a guide rather than a rule, noting that its scoring can be inconsistent and sometimes oversimplifies nutritional science.  It is best used to see the additives in food and cosmetics when they are too tiny to read on the label.  Some dieticians do not like the Yuka app, as they believe it unfairly rates certain food that should be in your diet.  It's free to use so check it out for yourself.
