The Swiss coronavirus contact tracing app looks set to be released later this month after the country’s Parliament gave its approval Monday. SwissCovid is based on the Apple/Google framework.
The SwissCovid app, whose use is voluntary, uses Bluetooth short-range radio and technology from Apple and Google to detect when a user has spent time close to another app user. It stores the data on the user’s mobile phone for 21 days, allowing notification of close encounters with infected people. Around 30% of smartphones in Europe run on Apple’s iOS operating system, with nearly all of the rest using Google’s Android. Together they host 99% of the world’s smartphones.
