They took place at the localities of the different Healthy Life centers, at the University campus, or in the home or workplace of the participants. Participants were given a test phone being either an iOS or Android, depending on which operative system they had on their own smartphone. Each session started with a short introduction of Plunde and an explanation of the aim of the research project. Further, the procedure for testing the usability of Plunde was explained. The participants were instructed to TA (verbalization of thoughts) while performing the problem-solving activities and it was emphasized that the purpose of these tasks was not to measure their digital skills but to test the usability of Plunde.The TA-sessions were recorded. Further, field notes were taken during the problem-solving tasks to record any observed technical difficulties encountered, ease of use, and learning as well as nonverbal behaviors related to the task management. The observer or interviewer (GS) reminded the participants to continue thinking aloud when they stopped doing so. If a participant was not able to solve a task after several attempts, the observer or interviewer provided a cue, in order to see whether and in what way, the task was solvable. After completing the TA-session, the participants received a cinema gift card valued 400 Norwegian kroner (US $40).
