A:Answer I answered previously but just now realized I was partly incorrect in my answer. Before you begin using your Fitbit device, you must connect it to your Fitbit account with a phone, tablet, or computer. Connecting your device allows it to transfer (or sync) data back and forth with Fitbit. Your data syncs to your Fitbit account, which is where you can see your stats, analyze historical trends, set goals, log food and water, connect with friends, and more.
