NHS open-sources contract tracing iOS and Android apps
Did the NHS have any good reasons why they weren&#x27;t going to work with Google and Apple (who surely have more expertise for this)?<p>Why not work on a single open source iOS + Android app that is shared and used in all countries so we can get cross border tracing?<p>If governments are concerned about Google and Apple getting access to data, what&#x27;s the argument against the above where each country uses their own servers to store tracing data?
