COVID Alert App, Canada’s national COVID-19 exposure mobile notification app is now active in Manitoba . The province became the fifth in the country to enable the app on Thursday.
The free app was officially launched in Ontario in July and is also now being used in Newfoundland and Labrador, Saskatchewan and New Brunswick.
The voluntary app works by exchanging random codes between smartphones via Bluetooth every five minutes.. It will notify users if they’ve been in contact with another user who has tested positive for COVID-19.
According to federal government website, the technology estimates how close users are based on the strength of the signals it receives. If a pair of users are assessed to be closer than two metres for more than 15 minutes, the app records it as an exposure.
