BACKGROUND: Mobile apps may encourage a lifestyle that avoids unhealthy behaviors, such as smoking or poor nutrition, which promotes cardiovascular diseases (CVD). Yet, little data is available on the utilization, perception, and long-term effects of such apps to prevent CVD. OBJECTIVES: To develop a mobile app concept to reduce the individual CVD risk and collect information addressing research questions on CVD prevention while preserving data privacy and security. METHODS: To validate the concept, a prototype will be built, and usability studies will be performed. RESULTS: We expect to determine whether it is possible to reach a broad user base and to collect scientific information while protecting user data sufficiently. CONCLUSION: To address CVD prevention, we propose a mobile coaching app. We expect high acceptance rates in validation studies.      «
