The Health Index (HI) is an algorithm designed to help give users insights into the quality of their health and lifestyle.
The Health Index is represented by a score on a scale of 100 points, so if your Health Index Score (HIS) is high, you can reasonably assume that your overall health and lifestyle is good and healthy. This index is recalculated every Monday based on data collected over the previous week from your device.
There are 3 main categories included in the scoring: Vitals, Activity, and Well-being. Each of these main categories has a max score value and has subcategories that help determine the main category score.
Each subcategory is weighted to help determine the overall score for the respective main category. The subcategories for each main one, and their weightings are shown below.
*If you would like a comprehensive explanation for the Health Index, please look at our Documentation.
