Veš kaj ješ is a free Android app developed by Zveza potrošnikov Slovenije ZPS. The app is designed to help users make informed decisions about their food choices by providing accurate information about the nutritional composition of food items. The app has a simple and user-friendly interface that allows users to scan barcodes of food items and get information about their nutritional value.

The app is connected to an extensive database that contains information about the composition of food items. Users can scan a food item's barcode using their smartphone camera, and the app will display information about its nutritional value, which can help them choose healthier food options. The app also uses a traffic light system to display the amount of sugar, salt, and saturated fats in food items. Lower values are displayed in green, while high values are displayed in red, warning users to limit their consumption of such foods.

Veš kaj ješ also allows users to manually enter information about the nutritional value of food items that are not yet in the app's database. Additionally, users can submit photos of food items that are not recognized by the app, which the developer's team will use to update the database. Overall, Veš kaj ješ is an excellent app for anyone looking to make healthier food choices and lead a healthier lifestyle.
