Yuka is an application designed to display practical product information directly to the consumer. Specifically, Yuka allows you to scan the labels of the food and cosmetics that you buy, such as food and cosmetics, and quickly know what they are made of and what their effects on your health and the environment are.
One of the advantages of this app is that, in addition to evaluating the quality and impact of the products that you want to buy, it also provides similar, but healthier and less polluting, suggestions. (However, its developers ensure that the criteria to define the level of a product are completely independent, without influence from any company or brand.)
Yuka is a free application that is also available for iOS.
