BMI Calculator for Wearables: Integration of Health Monitoring in Augmented Bracelets

ABSTRACT: Body Mass Index (BMI) is a widely recognized metric for assessing an individual's health status based on height and weight. With the rise of mobile and wearable technologies, health-related applications have become increasingly accessible. This paper presents the design and implementation of a cross-platform BMI Calculator developed using Flutter SDK, and its integration into an augmented wearable bracelet for real- time health monitoring. The application features a clean user interface, real-time BMI computation, and support for both metric and imperial units. By leveraging Dart for logic processing and Material Design principles for UI, the system ensures consistency across Android and iOS platforms. The wearable version extends this functionality by embedding BMI logic directly into a bracelet, utilizing sensors and Bluetooth modules for minimal user input. This hybrid approach offers a seamless, portable, and automated health evaluation tool, reflecting the potential of Flutter and wearable technology in personal health tracking.
