Apple released a new tool on Tuesday to show how many people in a region are reducing their movements amid the coronavirus outbreak.

Apple’s tool gathers anonymized data from Apple Maps users to show trends in movement. Google has released a similar tool using Google Maps and Android data, and Facebook has developed a movement tool that it makes available only to health agencies.

Apple’s mobility tracker lets you choose a location and see how well people there are social distancing. Hundreds of millions of people across the globe have been advised by governments to stay home to reduce the spread of COVID-19, the illness caused by the coronavirus.

The tool complements a new contact-tracing technology pioneered by Apple and Google that will use Bluetooth on smartphones to alert people when they’ve come in contact with someone with COVID-19 — however, that technology won’t be available for months.

Here’s a breakdown of how Apple’s new mobility-tracking tool works.
