Yawn. Produce data to assess its value. I already check my blood pressure and heart rate daily, and when running. Heck, my watch (which I wear only at the gym) gives me feedback -- at the moment but not something I need to record. Why why why? Those exceptions are luxuries without obvious advantages.

And, good lord, a SUBSCRIPTION to access its features. technically unnecessessary but yet another leech on my accessibility to data. (So many sites lately are behind paywalls. But you're receiving this data from my ring, WHY would I pay monthly for you to observe it and report?)
