The most useful part of this app (and it's free!) are its "what-if" analyses - how would my product react if I add or remove ingredients? This helps me predict problems before they happen! And because everything in your shopping cart has been preloaded you can literally check off what needs added/removed as soon as each item comes up during checkout without having first have them uploaded manually through another tool like My Cart Manager etc.. It also gives detailed info about common allergens so when we get home from grocery store there isn't any guessing game trying figure out which items contain problematic additives that will cause allergic reactions at dinner time :) There aren’t many downsides but sometimes certain features don‘ t work correctly such not being able to upload photos via QR code scanner instead requiring manual uploading after scanning image file directly onto.
