TAIPEI (Taiwan News) — Taiwan has launched a social distancing app to prevent COVID-19 transmission by tracking the distance between the app's users.

Introduced by Taiwan's Centers for Disease Control (CDC) and Taiwan AI Labs, the social distancing app uses Bluetooth technology and alerts users if they are exposed to confirmed COVID-19 cases.

According to the social distancing guidelines issued by Taiwan's Central Epidemic Command Center (CECC), people are advised to stay at least 1 meter apart outdoors and 1.5 meters apart indoors. The app will notify users if they have been less than 2 meters from a confirmed case for more than two minutes.

The app, which requires users to enter their Bluetooth identification codes, will collect personal data for the government with the stated purpose of improving public health, according to the app's introduction page.

However, the use of the app is completely voluntary. Users of Android and iOS can download it on their phones.
