Hi, @Or0213 , could you explain what the bottom picture is?
Are you saying that your phone counts more steps than your Fitbit does? That is not a sync issue. You will find that different trackers count different amounts of steps as they follow different algorithms, may have different equipment, and have different degrees of accuracy. Generally speaking I would have thought that a dedicated tracker, such as the Charge 5, would be more accurate than a phone count.
