An NHS app aimed at limiting a second wave of coronavirus will be trialled on the Isle of Wight this week, according to the transport secretary.

It will be the first place where the new contact-tracing app will be used before being rolled out more widely this month, said Grant Shapps.

The government will be asking the whole of the UK to download it, he told the BBC’s Andrew Marr Show.

“That will help with a lot of the automation of the tracking.”

Epidemiologists advising the NHS say that about 56% of the UK population – equating to about 80% of smartphone owners – need to use the app in order to suppress the virus.

However, they add that the spread of the disease could still be slowed even if the take-up is lower.

The Labour Party’s Nick Thomas-Symonds said there were shortcomings in the government’s plan as not everybody has a smartphone and there are issues around privacy and security.

“There are people for whom location services on their mobile devices are turned off for particular safety reasons,” he told Sophy Ridge on Sky News.

The government has also promised to recruit 18,000 people to do manual contact tracing, as it pursues a track-and-trace strategy with a view to lifting the lockdown.

Using Bluetooth, the free smartphone app will track when its users come into contact with each other, automating the tracing process.

If a user develops coronavirus symptoms, the disclosure could trigger an anonymous alert to users with whom they have recently had contact, enabling those people to go into quarantine or be tested.

It has previously been suggested that areas that trial the contact-tracing app could also have some lockdown measures eased early.

Contact tracing has been credited with helping to lift restrictions in other countries, when combined with other measures.

The app has raised concerns about the government and third parties being given access to people’s data.
