Calorie Counting and Scanning Watch
I love my heart rate monitor watch, but I would love it better if I didn't have to wear anything else, and it alone would be able to monitor my heart rate and calculate calories burnt. But what would really be awesome is, if it also had the capability of scanning products' bar codes and could tally for me how many calories I consumed versus how many I burnt. I think that would really help with weight loss and healthy eating goals.
