I've been using a vivosmart for about 2 weeks and generally like it. I get the inherent inaccuracies and am ok with that. My question relates to the apparent lack of internal consistency in calorie reporting. For example, right now my band says 2507 calories burned today; the GC mobile app in the steps page agrees, but in the active calorie page it says 1099 active calories and 1594 bmr calories for a total of 2693 (I do have a non moving activity that credited 81 calories, but this doesn't account for the difference). The accompanying bar graph has no relation to any of these numbers, showing a total of 1464 (presumably) active calories. What gives? Again, I like other features of the band and understand the limitations, but this is kind of annoying.
