ELCIES Health Data Aggregator API

The intelligent connector for health data

The Health Data Aggregator API is a bridge between lifestyle service providers and their health-conscious clients. Clients all wear different devices for monitoring health. This API helps to organize and personalize clients’ fitness, health and lifestyle data. You can also use user health and physical activity data to build your own intervention or prevention campaigns and more.
