mHealth services are becoming common all over the world. However, the acceptance and use of mHealth services are not always as expected. In this paper, we discuss the lessons learned from our recently finished research project “Health in Hand”. Based on the Swedish case study on using mHealth services to support patients with Type 2 Diabetes (T2D) in living a healthy life, we propose strategies for engaging the end-users in mHealth services. These strategies include moving user-driven participation from the margin to the center, building up a professional education team to support both patients and healthcare providers, strengthening user motivation through gamification and supporting the sharing of knowledge within and between different user groups. We believe that these strategies could improve the design of mHealth services through higher user engagement.
