Danish apps that help shoppers spot and boycott American goods are gaining popularity after President Trump's plans to buy Greenland. The AI-driven app "Made O'Meter," created by Ian Rosenfeldt, saw 30,000 downloads in just three days at the height of the political tensions. Since its launch in March 2025, it has crossed 100,000 downloads. Rosenfeldt explained, "If you use a bar code scanner, it's difficult to see if a product is actually American or not. And if you don't know that, you can't make a conscious choice." The app uses artificial intelligence to scan multiple products at once, identifying US goods and suggesting similar European alternatives, with over 95% accuracy. After a slow period, usage jumped when Trump's Greenland remarks peaked on January 23, with nearly 40,000 product scans in a single day. Although scans have dipped, about 5,000 daily scans continue. Besides Denmark, users in Germany, Spain, Italy, and Venezuela also use the app. Another Danish app, "NonUSA," also reached 100,000 downloads by early February. Jonas Pipper, one creator, said some users felt "a little bit of the pressure was lifted off them." Shoppers in Copenhagen showed mixed reactions. Retired navy officer Morten Nielsen said, "We do boycott, but we don't know all the American goods. So, it's mostly the well-known trademarks." Meanwhile, retiree Charlotte Fuglsang said, "I love America, I love travelling in America. I don't think we should register protest that way." Rosenfeldt admits boycotts won't hurt the US economy but hopes to influence supermarkets to favor European products. "It's become personal," he said, speaking of "losing an ally and a friend."
