Material/Methods:

The iterative Software Development Life Cycle framework was used to develop the application [3]. The first stage of the development process involved the use of semi-structured interviews to gauge the perspectives of experts, including healthcare professionals, child psychologists, educators, and game and mobile application developers. We then developed the application's content, architectural framework, and data flow logic based on the feedback obtained. Several wireframes were created to visualize the key concepts and storylines. These wireframes were shared with the stakeholders to gather their valuable insights. After several iterations, we developed a final prototype using the Thunkable platform [4] . Finally, 8 healthcare professionals were asked to rate the satisfaction and usability of the application using the ten-point System Usability Scale (SUS) questionnaire, which spans from 0 (worst imaginable) to 100 (best imaginable) [5].

Results:

Following the first round of semi-structured interviews, 5 key requirements were identified for the mobile application; "an age-appropriate, child-friendly user interface", "elements of personalization", "parental controls", "a reward system to enhance engagement" and "use of storytelling or metaphors to describe sensitive concepts". The first prototype of the mobile application was then developed to address these key requirements. For the user interface, we used a colorful, child-appropriate user interface with simple text written in a large, playful font. The final mobile application workflow is illustrated in Fig.1.
