It would be beneficial if the quantity of the recipe was displayed on the shopping list from the picture. This is an awesome and time-saving app, but without having the quantities, I have to look back and forth at the recipe and shopping list to understand how many pounds of chicken I need to buy. I bet if you gather a vocabulary database for numbers and symbols, Groce could pull that info on products and quantities when the app is scanning a photo.
It would look like this after the scan.
-1lbs chicken
-1 cup of milk
I couldn't find anything like your app, and it's great!
