Hi there, I'm thinking of updating my step tracker from a fitbit zip to a vivofit or vivosmart. However I use a Forerunner 610 to track my running. I like to count my steps while running so in theory I would like to use both at the same time. Does anyone do this currently or has anyone done it in the past with out issues? I don't want to spend the money on a fitness band if something screwy like double counting is going to happen. Thanks!
