Hi. I got my banglejs 2 about a week ago. The measured heart rate seems to be very low, approximately 75% of what I measure fingers on pulse. And this is pretty consistent, at rest the watch measures way below 50, when exercising not above 80. I fiddled with the settings also in different apps, pushed the watch on the skin but it's rarely showing the correct rate.
Does anyone have a similar experience? Any ideas what to try out?
