With the increasing emphasis on personal wellness and preventive healthcare, accessible digital systems that support continuous health monitoring have become an essential component of modern lifestyle management. Traditional health-tracking solutions often depend on cloud-based services or fragmented tools, resulting in higher cost, privacy concerns, and inconsistent user engagement. To address these limitations, this work presents Swasthya, an integrated mobile health-management application designed to operate fully on-device while delivering comprehensive monitoring of nutritional intake, metabolic parameters, vital readings, and medication schedules.

The system incorporates modular components that enable real-time computation of BMI, BMR, and TDEE using user-specific anthropometric data, alongside daily logging of calories, blood pressure, blood sugar, activity duration, and calories burned. A robust medication reminder framework is implemented through exact, device-level scheduling using Android’s AlarmManager to ensure reliable alerts, even under restricted power conditions. All records are persistently stored in a local SQLite database, while a redesigned interface employing a modern, health-centric visual theme provides clear visualization, structured navigation, and intuitive data interpretation.

The proposed application is lightweight, privacy-preserving, and optimized for offline use, making it suitable for individuals seeking consistent self-monitoring without dependency on external medical platforms. Its modularity allows extension into broader digital health ecosystems, including personalized wellness analytics, remote monitoring assistants, and smart healthcare IoT environments.
