Apple and Google today announced they were partnering up on a contact tracing system that works on both iOS and Android that alerts people when they’ve had contact with someone who’s contracted coronavirus. This collaboration between the two big smartphone companies would help health officials effectively track the spread of the disease while (ideally) not violating users’ privacy.
