The app gives a score out of 100 for each product scanned based on how healthy or harmful it may be and offers alternative products which may be healthier. The developers do not sell ads or user data and have a no influence policy which prevents brands from paying to place their products in the app. There is a premium version which is sold on a sliding scale (pay what you want) and it offers the ability to search for products or save the data to search offline and a few other things but the free version is totally functional for checking products at home or at the store.
