SwissCovid is the official contact tracing app of Switzerland. The app can be installed from the Google Play Store. The SwissCovid 2.0 app uses two types of contact tracing to prevent the spread of COVID-19.
With proximity tracing close contacts are detected using the bluetooth technology. For this the DP3T Android SDK is used that builds on top of the Google & Apple Exposure Notifications. This feature is called SwissCovid encounters.
With presence tracing people that are at the same venue at the same time are detected. For this the CrowdNotifier Android SDK is used that provides a secure, decentralized, privacy-preserving presence tracing system. This feature is called SwissCovid Check-in.
Please see the SwissCovid documentation repository for more details.
