Questionss
Jason,
My experiences with watches/fitness trackers is that they guess high on heart rate. Manually checking it sounds like a good idea though, interested to see how that turns our. My guess is your heart rate is more in the 170-180 range.
With the music, where are you downloading the music from? I stream all my music via spotify or apple music, and if I have to buy the music before downloading it that may be a dealbreaker for me on this watch.
