My Lords, I completely understand the concerns of those who may be struggling to download the app but I reassure the noble Baroness that the current app is supported by iOS versions 13.5 and higher, and by Android Marshmallow version 6.0. That covers by far the vast majority of phones. As I said, 89% of phones should support the app. They include, for instance, Apple iPhone 6S and above—a huge proportion of phones. We are debating a new initiative by Apple to bring in their own protocol that is particularly directed at developing countries which may not be able to support their own app. That initiative is not targeted at the UK. We believe that it may have some relevance in supporting downloads of the NHS app because the alerts created can perhaps be directed to the download site on the iPhone store to encourage those in the UK who have not yet downloaded the NHS app. The Apple initiative is a positive development that will be particularly well used in developing countries.
