Digital wellness technologies, such as physical activity applications, are potential solutions in promoting physical activity among young elderly. In this study, we qualitatively analyzed how can a physical activity application enable a more personalized support for physical activity among young elderly. As a result of our thematic analysis, we identified three different categories that represent the central wishes and needs of young elderly for physical activity applications to enable a more personalized support: 1) More holistic data collection that combines physical activity data and health-related data, 2) Sharing the physical activity data with healthcare professionals, and 3) Tracking small acts of everyday life. We suggest that these findings can increase the understanding on the viewpoint of young elderly and provide insights to be used in the design of personalized digital wellness services and products in the future.
