Like all the big tech companies, they are following the devil down this rabbit hole* of big data and machine learning trying to invent useful signal from giant piles of noise. Be extremely skeptical of the claims of being able to monitor detailed internal health things based on infrared sensors through your skin. It’s a fundamentally flawed idea that these low resolution, low quality sensors can pull out tiny signals if you just throw enough machine learning at them.
*apologies for that metaphor. What am I even doing.
