In my country, the government re-skinned the Singaporean open source covid19 app, which appears to be about the same thing as this one. The government didn't install it in every phone, but they made it mandatory for business-owners to check that you have the app enabled if you want to enter their premises. Everyone needs to eat/shop, so most people were forced to install the app. Every grocery store has a greeter at the door to check you have the app running, check your temperature, and squirt sanitiser on your hands. https://www.tracetogether.gov.sg/ https://www.tracetogether.gov.sg/
