Late last month, Apple released a free COVID-19 app that includes a screening tool from the CDC that tells you whether you need to self isolate, see a doctor or get tested. If you’re worried about privacy, the CDC says that it does not share the answers you give with Apple. The app also reveals the preventive measures you can take such as scrubbing your hands with soap and hot water for twenty seconds, maintaining social distancing by staying at least six feet away from others, and using a hand sanitizer that contains at least 60% alcohol.
