Trump’s Greenland crisis triggered a surge in apps designed to help shoppers boycott U.S. goods, though few American imports are on store shelves

The makers of mobile apps designed to help shoppers identify and boycott American goods say they saw a surge of interest in Denmark and beyond after the recent flare-up in tensions over U.S. President Donald Trump’s designs on Greenland.

The creator of the “Made O’Meter” app, Ian Rosenfeldt, said he saw around 30,000 downloads of the free app in just three days at the height of the trans-Atlantic diplomatic crisis in late January out of more than 100,000 since it was launched in March.
