Germany, Poland, and Saudi Arabia are among the latest countries to implement Apple's and Google's jointly developed Exposure Notification API in their respective COVID-19 contact tracing apps, available on the App Store.
Apple released the Exposure Notification API as part of iOS 13.5 last month. At the time, Apple said that 22 countries had requested and received access to the API, with the U.S. states of Alabama, North Dakota, and South Carolina also committed to using the API. Some other participating countries include Italy, Latvia, and Switzerland.
Apple and Google created this API to allow iPhones and Android smartphones to interface with one another for contact tracing purposes. If and when you happen to be nearby someone who later tests positive for COVID-19, you can receive a notification and take the appropriate steps to self isolate and seek medical help if necessary.
The API relies on Bluetooth, is designed with privacy in mind, and is disabled by default. Read our Exposure Notification guide for more details.
