Development and Usability of the “FORTEe Get Strong” App to Promote Physical Activity and Health Awareness in Children and Adolescents With Cancer During Intensive Treatment Using an App-Based Approach: Mixed Methods Study

This study provides novel insights into user experience of children, adolescents, and young adults with cancer with a gamified exercise and health education app. Unlike previous studies focusing on survivorship, this evaluation offers a comprehensive understanding of how digital tools can support patients in maintaining physical activity during intensive treatment. Apps with interactive, gamified elements may complement clinical care by providing low-threshold access to exercise and health education. The findings advance the field by identifying key facilitators and barriers to engagement. Future research should assess adherence, behavioral outcomes, and effectiveness in larger samples to inform clinical implementation.
