A formal test on 10 phones (5 iOS, 5 Android) carried out on 31st August 2020 by Adam Fowler of the Herald Protocol development team.
Correction - 2020-11-07
After reviewing the fair efficacy paper it was found that the UK population with mobile phones was double counted for some age groups. This has now been corrected in the below statistics and the paper.
This resulted in the Pcountry value for the UK changing. This doesn’t affect the probability of accurate risk detection but does effect the final Pspec and efficacy scores. The values that have changed are marked with an asterisk below.
