SmartSpark is a comprehensive health monitoring mobile application built with Flutter, designed to help caregivers monitor elderly users' health status in real-time through various sensors and smart notifications. The application leverages IoT (Internet of Things) technology to connect wearable devices and smart sensors for continuous health data collection and analysis.
SmartSpark provides a dual-user system connecting caregivers with elderly users to ensure continuous health monitoring and emergency response capabilities. The application integrates with IoT sensors and devices to track vital signs, medication schedules, physical activity, and provides real-time alerts for health emergencies through connected smart home systems.
