i have the go wear fit. i have never used the body bugg so i can not speak to that. what i can say is i love my gowear . i wear it everyday and it is an amazing motivator and i am going to assume the body bugg is the same. when i see my calories in are too close to my calories burned i get my butt moving- i work out every day where before it was more of a once in a while kind of thing. i look for my minutes of physical activity and my goal is to exceed that everyday.
