The Australian government launched a COVID-19 contract-tracing app on Sunday to help slow the spread of the coronavirus.
COVIDSafes uses bluetooth-tracing technology to find people who have been in contact with COVID-19 cases. Local health officials can then contact those who may have been exposed.
The app is the only contract-trace app approved by the Australian government. Participation is voluntary.
Digital contract tracing has been used in China, Singapore and South Korea.
Apple and Google plan to release their contact-tracing apps in May.
