Coronavirus: Crowdsourcing the race to trace

If you thought a global pandemic would end the trite observation that there’s an app for everything, I am about to disappoint you.
Because there are, indeed, already apps for COVID-19.
Specifically, there are apps for intensive contact tracing, which has been credited for keeping the outbreak under control in countries like Singapore.
Though the major work was done early with manual contact tracing, on 20 March, the Singaporean Government launched an app to ensure contacts were not missed.
