What you need to know
- The UK government has changed its contact tracing plans.
- It will now rebuild its app using Apple and Google's API.
- It is abandoning its own, failed centralized system.
After weeks of testing, bugs, and issues, the UK's contact tracing app is being abandoned in favor of an app built on Apple and Google's contact tracing API.
As reported by the BBC:
Despite the obvious drawbacks, the UK pressed on with a centralized tracking app that would store user data in central databases, even though it was made clear Apple and Google did not support this method, and that the app would be less effective as a result.
FAQ: What is the Google-Apple COVID-19 (coronavirus) Exposure Notifications system?
Without support for background Bluetooth usage, particularly on iOS, other apps using this method have run into catastrophic problems with the basic functionality of the app. Essentially, they are useless.
The BBC says the government is expected to announce the change today, and there is no indication as to when the new app might be rolled out, either for testing or to the general public. A British health minister yesterday admitted that a contact tracing app may not be ready until the winter, however, it's not clear if this was on account of the switch.
Apple and Google's contact tracing API allows health authorities to build an app that can trace who a person has had contact with, completely anonymously. The data can be used to identify people who may have had contact with COVID-19 so that they can isolate themselves, preventing further spread.
