I've been using LoseIt since my first iPod touch - the iPhone makes it even more effortless by simply bar-code scanning what you put in your mouth, or easily compounding fresh ingredients in recallable recipes then doling out estimated serving size. In this example, I rode my bike for nearly an hour an a half and it calculated 1,299 calories burned based on my estimated average speed. After my meltdown with Fitbit being nothing more than a glorified pedometer (its obtuse intake entry interface aside),
So I'm going to return my Fitbit.
