> The question I felt was unanswered by the article is have overseas apps actually delivered significantly better results than that? My country rolled out an app quite early last year. It worked well, didn't drain battery life, didn't need you to "sign up" or provide any personal details. The problem was pretty much nobody installed it, so it was basically useless. They also tried strict contact tracing, requiring people to register whenever they go into a bar or restaurant, but that also didn't work (most outbreaks were from meeting family or in the workplace). Now my country has given up on contact tracing and moved to accepting the virus will be here forever, and is trying to encourage more people to be vaccinated.
