Designing and Developing a Mobile Application for Monitoring & Visualizing Blood Pressure Data

High blood pressure is one of the major causes of cardiovascular diseases, renal failure, and even sudden death. To avoid developing these health issues, it is important to consistently monitor blood pressure levels. Monitoring blood pressure levels regularly allows people to observe changes in their blood pressure measurements and contact their healthcare providers for guidance if needed. The aim of this paper is designing and developing a mobile application that can assist individuals to better understand the changes in their blood pressure levels by introducing a novel approach to visualizing blood pressure data and managing missing data. Employing a user-centered design approach, we designed and developed an app. To complete this study, we conducted a literature review to identify key design requirements for such apps and then, designed our low-fidelity prototype based on these design requirements. Next, we consulted with two experts to obtain their feedback on the content, presentation, and usability of our initial low-fidelity prototype. Based on these experts' feedback we designed our mid-fidelity and high-fidelity prototype. Eventually, we conducted a user evaluation study to evaluate our high-fidelity prototype. The results demonstrated this app provides a clear visual representation of blood pressure measurements over time.
