Founded by James Park and Eric Friedman in 2007, Fitbit is a consumer electronics company known for its activity trackers. Fitbits are wireless-enabled wearable devices that measure data, such as the number of steps walked, quality of sleep and other personal metrics.
Fitbit’s first device, the Fitbit Tracker, uses a three-dimensional accelerometer to sense user movement. Fitbit launched an app for the iPhone in 2011, followed by one for Android and an official Windows app. It allows users to log their food, activities, water intake and weight, as well as track fitness goals.
