I'm hoping that you can revive some of the fitness tracking features of the Basis B1/Peak smart watches. I especially loved the galvanic skin response and skin temperature monitoring with the air temperature sensing. It was amazing to be able to identify stress by comparing these values.
I could literally identify when I was in an job interview or going dancing without just relying on my heart rate. My heart rate during the interview was relatively flat but elevated; however, my galvanic skin response spiked hard (sweating) and my skin temperature dipped without a similar air temperature change. On the other hand while dancing, I had reactive heart rate, varying galvanic, and rising skin/air temperature (lots of warm bodies).
