Exposure Notifications Express overview

Google and Apple created a turnkey solution called Exposure Notifications Express (EN Express), which makes it easier for public health authorities (PHAs) to support COVID-19 digital contact tracing efforts. Instead of building an Exposure Notifications app, PHAs can provide Google and Apple a configuration file that includes instructions and content, including the messaging to users and the risk parameters for triggering an exposure notification. This information is used to generate a custom app for the PHA.

EN Express is based on our open-sourced sample application provided on GitHub. PHAs can still develop custom apps, and existing apps using the Exposure Notifications API are compatible with EN Express. For countries that have already created a custom app on Android, the availability of EN Express does not change how your current application works. EN Express works on all the same devices as before (that is, Android 6.0 and higher).

EN Express provides another option for PHAs to supplement their existing contact tracing operations with technology without compromising the Exposure Notifications project’s core tenets of user privacy and security.
