The main issues I see with using this for any type of nutrition insight is that the vast majority of people that buy groceries are:
1 - buying them for more than themselves (e.g. family, partner, etc)
2 - You don't eat all of the groceries you buy every week. 1 bag of sugar may last a year.
3 - grocery receipts are really long and awkward to take pictures of.
4 - It doesn't take into account other food/nutrition you get outside of your home.
5 - The huge rise in curbside grocery orders means far fewer physical receipts
6 - Nutrition is very, very, personalized. There's not an effective way to make meaningful nutrition suggestions.
I suppose this could be useful to scan for any specific allergens, like if any of the groceries you purchased contain nuts or something. I love the idea of gathering stats about what you purchase though, whether it's food or not. I just assumed my regular grocery store (who are basically a tech company) could do a better job at tracking this than I ever could.
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).
