Track Fitbit Zip activity using a computer by installing the Fitbit uploader application on a PC running at least Windows XP or Mac running at least OS X 10.5. Plug in the accompanying wireless sync dongle so that the Fitbit Zip may transmit data to the computer for review.
The Fitbit Zip uses Bluetooth Low Energy technology to sync its data to a computer through its wireless dongle, which receives the device's data whenever it is within 20 feet of the device and in a low state of movement. You must install the Fitbit uploader application onto the computer before plugging in the dongle so that it may properly receive the data and upload it to an accompanying Fitbit account. It is also possible to sync the data through a smartphone that supports Bluetooth Low Energy technology to add the information to your profile in real time or by running the appropriate Fitbit app to manually sync data.
The Fitbit Zip tracks various stats about the person using it, such as the number of steps she takes in a day and the accompanying number of calories she burns. Through the use of an online account, a user may view the data over a period of time to determine activity levels and similar stats.
