Danish shoppers boycott US products via app

Danish people are upset with the US because the US president said something about Greenland, which is part of Denmark.

To show their anger, they are using an app called UdenUSA to find and avoid buying products made in the US.

The app scans the barcode of products and tells them if it's from the US.

If it is, the app shows a red 'X' to tell them not to buy it.

Many people in Denmark are downloading this app, and it's becoming popular.

Some politicians in Denmark are also talking about not buying US government bonds.

The US government says that Europe won't do this together, but the app is still growing and can now be used in many languages across Europe.
