People often face allergic problems or preferences to specific food ingredients. The app saves you from the hassle of reading through a list of ingredients on the packaging. User is given an option to select for particular preferences in food ingredients and then scan the bar code to check if product meets their expectation. The app also saves the preferences and could be easily modified.

This app is a standalone but the concept can be used in Amazon programs like Amazon pantry, Amazon fresh and Prime Now. Amazon can save user preferences and alert the user of the ingredients.
