    Koronavilkku is a contact tracing application developed by the Finnish Institute for Health and Welfare to help mitigate the spread of COVID-19 in Finland. The app was launched in August 2020 and is available for both iOS and Android devices. It uses Bluetooth technology to anonymously track encounters between users and notify them of potential exposure to the virus.

    Development and Launch[edit | edit source]

    The development of Koronavilkku was initiated in response to the COVID-19 pandemic as part of Finland's strategy to control the spread of the virus. The app was developed by the Finnish Institute for Health and Welfare in collaboration with several technology partners. It was officially launched on August 31, 2020, and quickly became one of the most downloaded apps in Finland.

    Functionality[edit | edit source]

    Koronavilkku operates by exchanging anonymous Bluetooth signals with nearby devices that also have the app installed. When two devices are in close proximity for a certain period, they exchange random identifiers. If a user tests positive for COVID-19, they can voluntarily upload their identifiers to a central server. Other users' apps periodically check this server and notify them if they have been in close contact with an infected person.

    Privacy and Security[edit | edit source]

    The app is designed with privacy in mind. It does not collect or store personal data, such as names or locations. All data is stored locally on the user's device and is encrypted. The use of random identifiers ensures that users remain anonymous.

    Adoption and Impact[edit | edit source]

    By October 2020, Koronavilkku had been downloaded over 2 million times, covering a significant portion of Finland's population. The app has been credited with helping to identify and notify individuals who may have been exposed to COVID-19, thereby aiding in the country's contact tracing efforts.

    Criticism and Challenges[edit | edit source]

    Despite its success, Koronavilkku has faced criticism regarding its effectiveness and the potential for false positives. Some users have reported issues with the app's functionality, such as battery drain and connectivity problems. Additionally, the app's reliance on user participation and voluntary reporting of positive test results poses challenges to its overall efficacy.
