What is the point of watchfaces with a heart rate indicator?
May be I am not understanding something, but what is the point of watchfaces with a heart rate indicator? Unless it is in the continuous measurement mode (which drains the battery) it would show an old measurement and therefore it would be useless?
if its not showing the latest one thats ok for a lot of people who focus on heart rate trends!
I believe they are coded to check your heart rate every so so. I'm not positive. But it is a good thing to have for some. Like @celes.meh mentioned its good for people with a heart condition, which I also have. I have faces with heart rate monitors and faces without and I myself cannot tell a difference in battery usage.
Yes, you can configure your watch to check heart rate continuously. The reason I am asking is that I am thinking to create a version of my AG Outdoor 12K with a heart rate indicator for people who do a lot of walking so they can monitor their heart rate but unless the watch is configured to measure HR frequently it would be misleading.
