SINGAPORE -- With over 10,000 deaths already reported in the COVID-19 pandemic, a mobile app is being rolled out in Singapore, one of Asia’s most tech-savvy nations, that will enable the government to identify possible cases more effectively and help curb the spread of the virus. 

The TraceTogether app works by exchanging bluetooth signals between mobile phones in close proximity. Records of these encounters are stored locally on the user’s phone for 21 days -- more than covering the normal incubation period of the virus.
