Signapore has an app that is free from the Ministry of Health. It is a voluntary download and tracks anonymous movement and contact with others. Can choose to report if you have the virus and the app notifies the recent contacts. Takes some trust in government, but it's clearly working for them. Not sure it could pass in this country...
