The public's trust is the key ingredient to a contract tracing app working, experts say. The success of a mobile app to contact trace Covid-19 cases depends on whether its users can trust their data will be protected, privacy and technology experts say. In Singapore, the opt-in smartphone app used Bluetooth for close-range swapping of contact information by smartphones. In Australia, more than a million people downloaded an official contact tracing app within hours of its release last night. Dr Verrall said the ministry urgently needed to work on an app to help with contact tracing.
