The most useful thing is to have a single place to store all the allergens that I have. It makes it easier to keep track of all my allergens and makes it easier for me to prepare meals for myself and my family. The software is a little confusing to use especially if you're not used to it. I also don't like that there isn't a way to print the ingredient list of a product. This has made it difficult to look up ingredient lists to make sure I'm not using the allergen-free version of something. It's a great way to store each of my allergens so that it's easier to keep track of them. It makes it easier for me to prepare meals for myself and my family by making it easier to find allergen-free versions of things like flour and sugar.
