Bands for tracking calories

Which ones are super great to use? I want to wear it all day and just got the nike fuel band but have noticed it doesn't show my heart rate to know if i am pushing my hardest in the workout and also the calories it shows for that workout are not even close to what they were with my chest strap/watch HRM.

and the nike fuel band doesn't show total calories for the day only during times the heart rate goes up enough to get it to count them, which is good if i only wore it for the workout but i want to see a whole day burn.

I have seen the bodybugg and bodymedia but i think you have to pay monthly to use them or maybe i misread.
