Techniques for implementing a platform configured to interact with a plurality of applications on a computing device to provide health information of an individual. The platform may be implemented by receiving information representative of a health state of an individual. The information may be provided by a sensor associated with the individual and provide data indicating the individual's physiological and/or emotional state. An indication of the individual's health state may be generated by selecting a value from a set of values representative of different health states. The indication may be provided through a programming interface to one or more applications. An application may provide context information associated with the individual at a time associated with the individual's health state, and the context information may be used to generate the indication.
