France approves release of controversial COVID-19 tracking app29 May, 2020
App measures proximity
The tracking app, called StopCovid, uses bluetooth to trace when a phone is in proximity to others who have the application.
Once someone records a positive test for COVID-19, the application sends out an alert to those who have been in contact with that person for more than 15 minutes so they can self-isolate to prevent further spread of the virus.
The phone app does not reveal the identity of the person who tests positive for coronavirus.Click here for reference
