I love my apple watch but the heart rate monitor is poor. Taking a reading every 10 mins is pretty pointless. I walk home look at my HR, it's 70. I run home (without using the activity app) look and it's 70. I sit down, eat my dinner, it's 140. I got a Fitbit Blaze. It records the HR every 5 seconds and 1 sec when recording an activity. The HR is much better in that respect. Using the Blaze at the moment. Anyone else find HR annoying? Apart from that and the lack of sleep tracking. It's awesome!
