Spark HR has become inaccurate
Is anyone seeing the accuracy of your HR data get worse? Lately my Spark Cardio HR + music is reporting very high heart rates, especially when running. Like it should probably be in the 140's and 150's and it's in the 160's and 170's. My watch is about a year old and this has been happening of late. It is even reporting 150s when I am casually walking my dog. Yes, I have done a few factory resets. Anyone?
