The basis of this project is to empower users to perform a more in-depth analysis of their health metrics. Comprehensive analysis of health metrics will enable individuals to make more health-conscious decisions, leading to better physical longevity and mental health. The end goal of this project is to use a suite of apps from which to extract physical, mental, and nutritional metrics and perform cross correlative analysis in each of these categories. Hopefully, utilizing the Health Tracker API, we can make insightful conclusions regarding an individual's health status leading to better preventative care and overall well-being.

The dictionary illustrated below contains key-value pairs of the following biometrics extracted from the Apple Health App. The intention behind this dictionary is to map concise naming conventions to Apple's naming convention type. The dictionary will make sense shortly when using the more practical naming conventions as arguments in our functions. The following table also contains a description column giving a brief description of the biometric and a link containing either a white paper or article from a reputable institution (Eventually all links will be replaced with peer-reviewed publications).
