If you always have your phone with you while working out, this wonderful new Polar product syncs with a free Polar app and displays your workout data in real time on your phone instead of the watch. Your phone will display your real time heart rate, calories burned, and distance covered. It also can map your route and shows you what zones you are working out in.
It's a great product and very simple to use. The band links to most gym equipment. You can set your phone on a treadmill when you workout or carry it with you when you walk. It's very accurate too.
FYI Pink has been discontinued
