This week, the commonwealth announced plans to launch a coronavirus exposure-notification app in early Sept. to more quickly break chains of transmission by using the new technology to notify people who may have been exposed. The state has a $1.9 million contract, using federal grant dollars, to deploy and maintain the app with software developer NearForm Ltd, the Ireland-based company whose app there has been downloaded by more than one-fourth of that country’s residents. The app is based on smartphone technology developed by Apple and Google, and will undergo a pilot project next week using state government employees and public health students, staff and faculty. In Sept., you can find the COVID Alert PA app for free to download in the Google Play store or Apple App store. This app is voluntary, but the more Pennsylvanians age 18 and older who adopt the app, the more successful efforts can be. The app does not enable any location services and is designed to be completely anonymous.
