Causally Linking Health Application Data and Personal Information Management Tools

no code implementations11 Aug 2023 Saturnino Luz, Masood Masoodian

The proliferation of consumer health devices such as smart watches, sleep monitors, smart scales, etc, in many countries, has not only led to growing interest in health monitoring, but also to the development of a countless number of ``smart'' applications to support the exploration of such data by members of the general public, sometimes with integration into professional health services.
