Mass testing, a critical goal we need to quickly achieve but what's the best digital contact tracing approach? NHSX are looking at a similar model to Singapore's TraceTogether app, privacy should be kept with a decentralised approach.

There'll be other privacy issues but as long as app makers are open these should be addressed.
I did have concerns of the use of Bluetooth but if security is ensured, it's an accurate method to trace contacts.
But how will the majority of the public adopt the app?

Not even half the population of Singapore are using the TraceTogether app so what is the best way for mass adoption?
One way could be for phone operators to include the app into an update but convincing the majority of the public to use it could be hard.

I'll keep adding more to this thread about the UK's app and comparing other countries approaches.
