Title

Development of mobile application for BMI and fitness information tracking

Abstract

In response to the escalating prevalence of overweight and obesity in Zimbabwe and beyond, this study introduces an innovative mobile application integrated with IoT devices for Body Mass Index (BMI) and fitness information tracking. The primary research problem addressed is the widespread difficulty individual’s face in effectively monitoring health metrics due to fragmented systems and limited access to reliable health technologies. The aim is to offer a user-friendly, automated, and accessible tool that facilitates informed health decisions and promotes sustained lifestyle changes. The system employs a combination of hardware and software components, including Arduino-connected weight and height sensors, integrated into an Android-based mobile application. Key health metrics—BMI, Body Fat Percentage, and Basal Metabolic Rate (BMR)—are computed automatically, and the application delivers personalized recommendations based on real-time sensor data. The research methodology follows an evolutionary prototyping model supported by agile development, ensuring iterative refinement through stakeholder feedback. Initial findings demonstrate that the application not only simplifies the tracking process through automation but also enhances user engagement via data visualization, social features, and secure information sharing. Preliminary testing indicated high reliability in metric calculations and strong user interest in personalized features. The broader implication of this study lies in its potential to support healthcare delivery in resource-limited settings, empower individuals in self-monitoring, and inform digital health policy strategies. This project contributes to the field of software engineering by demonstrating how mobile and IoT integration can produce scalable, ethical, and impactful digital health interventions
