With THI’s support, MAW Greece will design and launch a child-centered Companion App to enhance the psychosocial support provided throughout the Wish Journey. The project will cover strategic research, educational content development, gamification design, UX/UI prototyping, and full technical development . Developed in collaboration with expert partners, the app will integrate age-appropriate guidance, emotional support tools, and playful interactive features—strengthening communication with families, improving accessibility, and supporting the emotional well-being of children as they await the fulfillment of their wish.
