Read our privacy policy The troubled contact-tracing phone app to curb coronavirus will not be ready for use in crowded tower blocks until at least the autumn, a local authority leader has warned. “We can all imagine what will happen if you have a tower block where you are reliant on Bluetooth,” Fiona Twycross told a London Assembly meeting “You might get inaccurate readings from people who haven’t actually been in contact with people.” Ms Twycross added: “It is more important that we get the app right for when we need it in the autumn, than rush it out before we’re ready.” Arguing the physical contacting of people suspected to have been in contact with coronavirus carriers was more important, she said: “The test-and-trace and isolate programme is not reliant on the app – nor should it be “We can’t have a system which it is entirely reliant on people having the right technology and downloading an app to protect the public.” The criticism comes as the department of health and social care finally unveils the first statistics from the trial of the app on the Isle of Wight, after criticism of the delay. Ms Twycross questioned whether the app would work in London, “although it might work on an island”, also suggesting the entire scheme was further delayed by adding: “I understand that is it is due to come out in the autumn.” Ms Twycross questioned whether the app would work in London, “although it might work on an island”, also suggesting the entire scheme was further delayed by adding: “I understand that is it is due to come out in the autumn.” In the Commons, there was further criticism that the Isle of Wight was chosen for the app trial, when the island has an “overwhelmingly white population”. But Michael Gove, the cabinet office minister, said the island was the right place because it was “geographically secure”, enabling the government to learn lessons “rapidly” about the app’s operation.
