A SaaS that shows you who is checking you out.

For your body?? What do you mean? Like human body?

Yeah. A single service bundling other services and potentially my doctors into a unified interface and analytics platform.

Does such a service exist?

How about Gyroscope? https://gyrosco.pe/

Sort of right.

I am not looking for a solution that tracks my whole life. Instead I would like to focus on health with Segment.com-like integrations into other services (https://segment.com/integrations) to always know what's going on with me.
