The present invention relates to an event based tracking, health management, and patient and treatment monitoring system, and, more particularly, to an event based tracking, health management, and patient and treatment monitoring software system including a unique/custom scanable code (e.g., a quick-response (“QR”) code) created for a specific positive/negative event which is tied to at least one specific phone number or other unique identifier of a mobile device, and a software application stored on the mobile device which enables the mobile device to (i) scan the unique QR code (on a card or other item), and (ii) log QR code data indicating the completion (positive) or non-completion (negative) of the event (and related information) in real time into a particular profile in a database (e.g., in a cloud server) for event validation and authentication, health management, and/or patient and treatment monitoring, and for reporting the QR code data (and related information) to authorized clients.
