Social Distancer was taken down from the app store after Apple introduced new policies to prevent the spread of false information of Covid-19. That means no social distancing or Covid-19 related apps are allowed to be published by individuals. The app is available here for download for those of you who want to use it. If anyone who is reading this is part of a recognized institution (hospital, government agency, university) and would be willing to publish it, the developers of both the Apple and Android version would be willing to do so.
