The NHS Covid-19 App Has Only Had Half The Downloads NHS Advisors Say It Needs To Help Stop the Coronavirus Pandemic

The official NHS Covid-19 app has only been downloaded by 40% of adults with eligible smartphones—half the number researchers say is needed to effectively halt the spread of the virus.
Experts from the University of Oxford claimed in April that 56% of the general population, or 80% of current smartphone owners, would need to use a contact-tracing app for it to be effective in helping stop the coronavirus.
Speaking to the BBC earlier this year, Professor Christophe Fraser, a member of the modelling team which advised the NHS on the contact tracing app, said this was “a very ambitious target”.
But he added that the app would still have an effect if fewer people downloading it, with his team estimating that one infection could be averted for every one to two users.
The app, which tracks who a user has been in contact with using anonymous bluetooth data, has now been downloaded 19 million times since it went live on 24 September, according to the Department of Health and Social Care (DHSC).
These latest figures came alongside an announcement of the latest updates to the app, which included improvements to its accuracy and fixes to prevent incorrect exposure notifications.
Following its launch, some users complained that they had received notifications from the app telling them to self-isolated which later disappeared.
But, a DHSC spokesperson insisted such messages were "default privacy notifications from Apple and Google, who provide the underlying framework on which this and many other countries' Bluetooth contact tracing apps are based."
The most recent update has reportedly improved the app’s ability to judge the distance between users and so better estimate when there is a risk of infection.
Gaby Appleton, director of product for NHS Test and Trace, said she hoped these changes would “make it as simple as possible to keep users and their loved ones safe”.
“We are thrilled that over 19 million people have chosen to download the app to help protect their loved ones while preserving their privacy, and that over 680,000 QR codes have been created by businesses to support digital contact tracing,” she continued.
The DHSC also announced that the NHS Covid-19 app, which currently only operates in England and Wales, will soon become interoperable with contact tracing apps in Scotland, Northern Ireland, Jersey and Gibraltar.
Under a proposed system set to be launched in November, users who test positive on any of the apps can choose to upload their anonymous Bluetooth key to all app users across the UK.
