A:AnswerI 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.
A:AnswerYes, I think it can. I only have the regular service because it is free, but you can purchase a "premium" service and I think the GPS is a part of that
A:AnswerYes. To get the sleep stages graph, just wear it to bed and,in the morning, open your Fitbit app on your phone, give it a little time to sync up with your watch and then push the sleep icon button.If,when you go to bed, you push the button in the app on your phone telling it that you are going to sleep, it will not give you the graph. That is only to be used when you don’t have your Fitbit on you.
A:AnswerI don't know about playing tennis. My versa lite smartwatch fits snuggly, but comfortable on my wrist, I do wear it at the gym, just not sure about tennis.
