Immuni is the official contact tracing app for Italy with 10mm downloads.

  Which is not "nobody", but it is not even close to the statistical threshold of "enough use, helps prevent the spread of the disease"

    Globally yes, but the thing about contact tracing is that it is inherently local. So getting 1/6:th (if we assume most of those downloads are in Italy) of a single country would probably be helpful in preventing spread.

      It means 1/36 interactions will be recorded by the app, which is almost certainly not enough to move the needle.
