The Apple COVID-19 App, built in partnership with the CDC, has up-to-date information from "trusted sources" and a medical diagnostic screening questionnaire. Apple says the answers to the questions get encrypted and never leaves the device, all good. BUT they do not explicitly say whether the APP REPORTS YOU AND YOUR LOCATION? Researchers start tearing it down! We need answers!
I tried out the Website.
I told them I have a cough (I figured I had to say something) and I'm old. I have no other symptoms or risks (no travel or exposure). The site says to self-isolate. Cough is one possible symptom of CoVID-19.
Then I told it I had aching and chills, and vomiting (but no cough). The site says to self-isolate. Aching, chills, and vomiting are not symptoms of CoVID-19.
I'm not terribly impressed.
