Calorie Counter

Options
Hi all,

What is the best way to count all calories burned during the day, miles walked, steps, heart rate and that syncs with my fitness pal? There are so many options. Not sure what is the best. I am looking for a wristband that I can wear all day long which can track all the above and automatically sync with my fitness bal. I know Body Fit has a arm band but that one is too bulky to be worn all day long.

Thank you
