I have a vivosmart. i view my reports on my laptop browser. In the Active Calories report, my total active calories show 2027, while the active calories in Total calories report shows 3292 (Total calories - BMR). Same 3292 is shown in Calories in / out report. So, basically this figure is mismatching with the figure in Active Calories report.
Besides every morning when i wake up, i see that my vivosmart shows 70-76 steps taken, while i never wake up and walk in my sleep.
