Anyone else notice that when you want to check your heart rate the apple watch takes up to a 30- 60 seconds to calculate it. I have a fitbit hr as well and its immediate to calculate the heart rate the apple watch is too slow to calculate heart rate i mean you could be done a whole set or a work out by the time it tells you. And its not that accurate because it gives you the rate for 60 seconds ago not the current one. Im curious if anyone else has tested this.
