California is rolling out a new, voluntary smartphone tool to alert people if they’ve spent time near someone who has tested positive for coronavirus.
Gov. Gavin Newsom announced the tool, CA Notify, on Monday during a press conference, adding people could opt-in to use it starting Thursday, Dec. 10, 2020.
