This document discusses how wearable devices and mobile apps can integrate big data in healthcare to predict diseases and provide early assistance to patients. It proposes a scenario where a wearable device collects a heart patient's real-life data which is analyzed in the cloud using predictive algorithms. This allows alerts to be sent if anomalies are detected, helping ensure therapy adherence and reducing health risks. The solution involves wearables transmitting data to a smartphone app and cloud for storage, with a portal giving clinicians access to monitor multiple patients' data while respecting their privacy.
