Does the fitbit not keep good enough track of calories

[indian]

I have noticed a lot of people using other tracking devices for calorie count. Does the fitbit not do a good job? Am I missing something? I want to lose weight and maximize my chances, help!!!!

I use a Heart rate Monitor for more Accurate calorie count when Exercising.

Fitbit is not a HRM. I use it for every thing else.

I find them to be different by about 15% and it can go either way
