Apple-Google coronavirus app plan by NHS

The UK’s coronavirus contact-tracing app is set to use a different model to the one proposed by Apple and Google, despite concerns raised about privacy and performance.

The NHS says it has a way to make the software work “sufficiently well” on iPhones without users having to keep it active and on-screen.

That limitation has posed problems for similar apps in other countries.

Experts from GCHQ’s National Cyber Security Centre have aided the effort.
