    I like this product because it helps me stay on track with my diet goal. Every day I log what i eat and how much I have exercised. You do that, and it really makes you rethink eating a candy bar, because you see how far behind it makes you with your daily goal. For me, the hardest thing about dieting was remembering that I am dieting, and these products help me do that.

    Fitbit is headed in the right direction, just not there yet. Since this not not a pedometer it doesn't really track steps, just arm motion. So it'sdoesn't provide a true step count. I work out hard for at least an hour each day but the dashboard usually shows less than 30 mnutes activity for the entire. Not sure what the measure of activity really means. And since it does not monitor heart rate I can only assume the calories burned is a function of weight (which user enters into the app) and steps taken. I show pretty much the same calories burned each day no matter how active, or inactive, I am that day. I do like the sleep monitor. Based on my movement in bad it shows me how often I am restless during the night. Overall, lots of potential but not robust enough yet.

    The weekly report is a treat. If and when I figure out how to get every thing working, I think it will be a great incentive to my attempts to improve my health. I like the scale that goes along with the fitbit too. I haven't been able to get the sleep tracking part working yet.
