Fitbit From Wikipedia, the free encyclopedia
Fitbit Inc. is a company headquartered in San Francisco, California, United States. Founded and managed by James Park and Eric Friedman, the company is known for its products of the same name, which are activity trackers, wireless-enabled wearable devices that measure data such as the number of steps walked, quality of sleep, and other personal metrics. The first of these was the Fitbit Tracker. The average price of a Fitbit is between $60 and $130, depending on the model. However, data cannot be downloaded off the Fitbit website unless one pays the premium membership price of $49 per year. Intraday data analysis cannot be downloaded at all.

The Fitbit Tracker uses a three-dimensional accelerometer, similar to that in the Wii Remote, to sense user movement. The Tracker measures steps taken, and combines it with user data to calculate distance walked, calories burned, floors climbed, and activity duration and intensity. It uses an OLED display to display this and other information such as the battery level. It also measures sleep quality by tracking periods of restlessness, how long it takes the wearer to fall asleep, and how long they are actually asleep.
A wireless base station is included to receive data from the Tracker and also charge its battery. When connected to a computer the base station will upload data to the Fitbit website, where a number of features are available: seeing an overview of physical activity, setting and tracking goals, keeping food and activity logs, and interacting with friends. Use of the website is free.
The Fitbit Classic tracked only steps taken, distance travelled, calories burned, activity intensity, and sleep. It was designed to be a small black and teal device that could be clipped discreetly onto clothing and worn 24/7.
