A friend has recently showed me his fitness tracker. I was shocked to find his was able to "measure" BP, while my FR935 cannot - nor can the newly introduced FR945 or Fenix 6. Mind you: the FR/Fenix are 10x the price of that fitness tracker - but lacking when it comes to such features (and abundantly rich is other features...)
Now, I know BP values displayed by the fitness tracker are only an estimate (but a pretty decent one - I have read some articles; apparently, this is nothing new - same as my ignorance.) Continuous PPG (Photoplethysmogram) monitoring allows for a number of interesting physiological indicators to be estimated. Diving into the SDK (I was actually exploring the option of developing such widget myself...) , it would appear as if Monkey C does not provide an application with enough data to be able to estimate these indicators (possibly, the H/W itself does not support providing this data to the app, "simply" converting the HR signal to simple 1/0 sequence rather than providing a DAC converted value; I don't really know the FR internals...)
Surly, I don't expect the FR to function as a medical device. However, having such indicators available would be interesting, and of great value.
Should I wait for FR955/Fenix 7? Is this something that might be of interest to other users?
