LONDON — An app to help to contain the spread of the coronavirus will finally be launched in England and Wales on Sept. 24, months later than the British government had hoped.

The Department of Health and Social Care said in a statement that trials in the London district of Newham and on the Isle of Wight, off the southern coast of England, had shown that the app is “highly effective when used alongside traditional contact tracing to identify contacts of those who have tested positive for coronavirus.”
