GoFit / Body Media Fit question

Options
I know you can't access all the info w/out the subscription, but will the display be accurate if you don't have a subscription? You put your age and weight in online so if I cancel my subscription and just want to use it as a calorie counter with the display, will it count for someone of average height and weight or my height and weight?

I really love it, but I don't think it's worth $12 a month to access the information. It would be PERFECT if the software was included.
