>The heart rate measurement doesn’t work so well (it fails two times out of three) but it also shows steady downward progress. Look into buying a 3rd party HRM (heart rate monitor). There's a fair chance that a chest strap will broadcast to your device and that you won't need a watch. In my case, my treadmill's metal pads wouldn't read my HR consistently. The strap that came with the Polar FT7* (I think it might be an HR1?) broadcasts to my treadmill, which solves the problem for me, and lets me track even if I forego the watch. The watch (more or less a display unit for the chest strap) is handy for resistance training or exercising outside, though. *Wirecutter has an article covering what are probably better alternatives: http://thewirecutter.com/reviews/best-fitness-tracker/ http://thewirecutter.com/reviews/best-fitness-tracker/.
