"A smartphone app launched by the Canadian government to help slow the spread of COVID-19 could be less effective in the latest wave of the pandemic, says an expert.
The COVID Alert app, launched in July of 2020 by the federal government, works by using a cellphone's Bluetooth signal to detect other app users who come within two metres for at least 15 minutes.
If a user tests positive for COVID-19, they're supposed to receive a code from their local health authority, which they enter into the app."
