I too want to see Vivofit sync with MFP. I had initially ordered Fitbit Force due to the fact that it syncs with MFP but low and behold right before it was to ship it was recalled. I went with the Vivofit because a friend of mine ordered it and then decided to stick with her Fitbit Flex and sold me her Vivofit. I like it so far but if it turns out that they decide not to allow syncing with MFP I will most likely order whatever the next generation of Fitbit is.
Please link somehow to a calorie/food tracker. This is a function I need. Considering returning because of this. Also calorie counter is not at all accurate - 90mins at gym and 8hr into the day and my Vivofit says 260 calories. Even at a sleeping BMR = 480-calories. hummmm....
