(AP) — Rhode Island introduced a smartphone app Tuesday that state officials say could help public health workers trace the contacts of COVID-19 patients and connect them to testing and other resources. > The Crush Covid RI app uses satellite-based GPS technology to track people’s location if they opt into that feature. Someone who then tests positive for the coronavirus can volunteer to share their 20-day location history with the public health department.
