No.
A tool has to serve a strategy. The bleedin' obvious problem is that it is not.
If you want to test and trace to reduce infection rate you need to notify all suspected case.
If you want everybody to catch it you should notify nobody.
The middle is just theatre.
again the obvious, it is too senstive
Last week and the 2 weeks before over 500,000 pw were pinged
Did we see ANYTHING like that number of cases - NO
An app that had no false positives or negatives would be wonderful, but would be so far beyond what is possible that it would be magic.
The best an app can do is to identify people who are at an elevate risk of becoming cases. This will be far more than actual cases.
What you do then depends on what your goals are. If you want to reduce the number of cases you ping and isolate everybody with an elevated risk.
If your goal is not to reduce the number of cases, but rather to be annoying, but not too annoying, you ping the top 10,000 or whatever you decide is the appropriate level of annoyance.
