From governments to big tech companies—everyone has a system, and no one’s happy about it

The Trouble With Tracing Apps

Contact-tracing apps seemed like they might turn out to be technological saviors when they made their debut in March. The hope was that some semblance of normal life could return if people knew when they came into contact with someone carrying the novel coronavirus. Yet as the weeks go by, that’s not happening. The apps, most of which work by using Bluetooth to connect phones to each other and ultimately let people know if they’ve been exposed to the virus, have instead raised hackles about privacy and surveillance. And there are worries about whether the technology is even effective.

People from Singapore to San Francisco say they don’t want to use them, citing technical problems and skepticism that privacy protections are for real. A system developed by Google and Apple Inc. isn’t being widely adopted because of limitations it imposes on governments using its technology. Instead, many countries have decided to come up with their own solutions, which are usually incompatible with apps used elsewhere, making them useless for travelers. And in India, Southeast Asia, and much of Africa, smartphone ownership is too low to reach the threshold for contact tracing to be effective, which is at least 60% of a population.
