An app called NonUSA is surging in popularity in Denmark; it “helps you identify and avoid American products in everyday life”. (Ironically, iOS-only for now…) https://www.the-independent.com/tech/us-boycott-app-nonusa-denmark-greenland-b2905574.html

@kottke I mean there is the ironically named "Made In USA" for android ... lol (link goes to playstore)

EDIT: it might not have the desired functionality but I leave it despite my doubts, because its funny. There is a barcode scanner "Made in from ?" which probably actually does provide the desired feature.
