Transport Secretary Grant Shapps tells BBC Breakfast that the sensitivity of the NHS Covid-19 app will probably be reviewed as coronavirus restrictions change.
The app detects the space between customers and the size of time spent in shut proximity, however the finish of the 1m-plus rule on 19 July could imply the app’s sensitivity must be decreased.
It comes amid an enormous rise in alerts as infections surge, as those that obtain an alert by way of the app are requested to remain house for as much as 10 days.
