That way there is no need to memorize the address and the app is more easily accessible by clicking the icon.

The app can also be used on a computer desktop browser together with a web cam. Below are some detailed instructions on how to use the app on a phone and how to “install” it to the home screen:

  3. After the camera is activated, scan a QR code: aim the camera at the code and wait for the camera to focus. If the code is detected, the identifier will become visible in the identifier field in the bottom left and the specimen data view page opens.
  4. In the bottom right you can change between viewer and edit pages by clicking the text “Kotka viewer” (default view).
  5. “Installation”: When you go to the address, Chrome may prompt you to add the app to the home screen (aloitusnäyttö). Click Install or choose from the top right menu “Install Kotka” (“lisää aloitusnäyttöön”) and click "Install" ("lisää"). Close your browser and the Kotka icon should be on your home screen. After this you get to use the app via the icon without the need to memorize the address.
