TraceTogether

TraceTogether was a digital system implemented by the Government of Singapore to facilitate contact tracing efforts in response to the COVID-19 pandemic in Singapore. The main goal was a quick identification of persons who may have come into close contact with anyone who has tested positive for COVID-19. The system helps in identifying contacts such as strangers encountered in public one would not otherwise be able to identify or remember. Together with SafeEntry, it allows the identification of specific locations where a spread between close contacts may occur.

Released on 20 March 2020, the system initially consisted only of an app by the same name. However, this was later supplemented by a physical token mainly intended for elderly and children who may not own a smartphone, or those who prefer not to use the app. The app was the first main COVID-19 tracking app released in the world and its development encouraged the development of similar apps in other countries.
