I just received my Neo yesterday and am really liking it. One thing I was hoping it would do (and I found out today that it wouldn't) is track calories burnt while doing Tai Chi. I turned it on to the walking app (closest activity) and the heart rate monitor would change during the practice but it registered zero steps. The pedometer also registered zero steps. I was hoping by the fluctuation in the heart rate that it would register calories burnt but I guess it doesn't. Maybe the Gear 4, 5 or 6 Neo will. It would have been interesting to have the heart rate monitor on for 24 hours and see how many calories were burnt over the course of an average day.
