Helpful #nhsxCOVID19app explainer [Thread] 👇 from @hadleybeeman.
For more technical background, see github.com/nhsx/covid19-a… for, e.g. system architecture (v3) and (predominantly @AWS) infrastructure.
Of course, we're still waiting for the results of the trials...
...and, as the BBC's write-up concludes, evidence that #ExposureNotification works in practice is "scant" - in ALL countries attempting it, not just the UK:
bbc.co.uk/news/technolog…
Efficacy (as in NZ) will most likely come from #QRcheckin, which could've been done months ago.
Bottom line, will I be downloading it? Already have - as I did with the other versions, to see what they did.
Will I be using it? Probably. Not least to avoid having to hand over personal details; combined with regular data deletes/resets.
Will I trust it to keep me safe? No...
...because there is literally no evidence that it will. Plus it's highly dependent on #testing being available, accurate and quick - and we're struggling to get more than 1 out of those 3 right at present.
Meanwhile, #Hands #Face #Space
N.B. Geeks like me may be interested to compare the three #PrivacyNotices:
1) Full notice, updated today (24 Sept):
gov.uk/government/pub…
2) Notice for "young people":
gov.uk/government/pub…
3) "Easy read" notice [PDF]:

Interesting behaviour on the @Android version of #nhsxCOVID19app: it appears you cannot use ANY of the other (non-#ContactTracing) features of the app if you switch off #Bluetooth and/or #Location on your phone - even if you've also switched off 'Contact Tracing' in the app...
...there seems no good reason why this should be, if #Bluetooth and #Location are really only required for #ExposureNotification - why do they have to be switched on (thus, e.g. passing your Location to other apps on your phone) for #QRcheckin, basic advice and #SymptomChecking?
Maybe someone will do us all a favour (and keep @DHSCgovuk honest) by offering a standalone #QRcheckin app?
#FeatureBloat is one thing; denying access to functions on the basis of a feature that is *supposed to be under user control* entirely another!
Six criteria for success for the #nhsxCOVID19app from @AdaLovelaceInst:
#Efficacy!
#Downloads (also regular #use)
#AccessToTesting
#Adherence (to #notifications)
#MeasurableImpact
#AddedValue
