A coronavirus contact-tracing app for England has edged a step closer with the launch of a new public trial, after months of delays. From 13 August, the Isle of Wight will be in the trial forefront once again, alongside NHS volunteer responders across England, followed shortly by the London borough of Newham. It comes after the government ditched efforts to develop its own technology in June amid accuracy issues and concerns about privacy. Despite initial hype, officials have warned that contact-tracing apps are not a ‘silver bullet’ for coronavirus, but could support the NHS test and trace effort.
