I wear a jawbone. It is like a fitbit but does not tell time or anything about you. The jawbone tracks your steps and sleep and other things. When you hold on to the botton and hold it still, then it will vibrate and will chage to day or night. You only do that when you are awake or asleep. You will have to open the app and make sure that it is synced in. It comes with a special charger that you use. You put the jawbone on your left hand. When you do special excercices then you press the botton twice, and press it once when you want to get back. A jawbone can do lots of things than a fitbit.
