An eco-system for tracking a user's physiological parameters comprises a central sensor and at least one remote sensor in wireless communication with the central sensor, a portable device readily accessible to the user, and a cloud platform. Each sensor may be worn by the user and measure data indicative of one or more of the physiological parameters. The central sensor may receive and process the measured data from each remote sensor and processes its own measured data. The portable device comprises a receiver wirelessly receiving the processed data and instructions from the central sensor； a processor running a mobile application handling the processed data and instructions； and a transmitter transmitting the processed data. The cloud platform receives the processed data from the transmitter； analyzes the received processed data； and transmits the results of the analysis to at least one of the portable device and an authorized healthcare entity.
