I believe this is incorrect. The app is not some sort of sci fi tracker that will be going off anytime it senses someone with CV-19. It will only notify you if you have been in contact (15-20 mins at 2m) who subsequently notifies the app that they have had a positive test result. There are lots of social media rumours about how it will work, most are incorrect- as usual!
