You nailed all the limitations of this app (and others like it) on the head :) The reality is that there will probably never be a foolproof way to understand our consumption/nutrition habits 100%, so my goal with this was to make it easier to understand at a high level what was in my groceries (that didn't require individual scans of each product).

I'm sure most chains have the purchase tracking for ads/marketing, but not sure how their data incorporates nutritional/ingredient data (if at all).
