This company makes health and wellness equipment. Unfortunately, they suggest the consumer use a horrendously clunky app called Beurer HealthCoach. I only use it with the BF70 scale, which calculates your BMI, Body Fat, Muscle % and level of hydration based on your age and height and because you can add other individuals so that you don’t have wildly fluctuating information.

I can’t see any mention of an API, so with no way to access the data, this one isn’t possible.
