@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.

Wouldn't it be great if your phone could just magically tell you whether the products you want to buy are Canadian or not? Well, now it can — thanks to savvy entrepreneurs across the country who've created apps to meant to help shoppers identify the origin of everyday staples.
@kottke When I moved to Germany in 2010, I saw how germans still had this idea of the US as the nation that liberated them from naziism.
As a Canadian, I knew that that US was looooong gone.
Really obvious they know that too, now.
We have a similar app down here (Australia) called *Bring Back Australia* that, when you scan the UPC, tells you where the product comes from and what company gets the income from it. It also clearly differentiates between Australian *owned* and Australian *made*, the latter frequently indicating that the ingredients come from overseas.
A bit parochial, but it comes in handy when we're particularly annoyed at a country 😁.
