Fitbit
Fitbit is a small device to track your physical activity or sleep. You can wear the device all day because it easily clips in your pocket, pants, shirt, bra, or to your wrist when you are sleeping. The data collected is automatically synched online when the device is near the base station. After uploading, you can explore visualizations of your physical activity and sleep quality on the web site. You can also view your data using their new mobile web site. You can also track what you eat, other exercises that you do, and your weight.
