A fun way to measure your fitness. The Fitbit Zip Tracker records steps, distance, and calories burned - then automatically syncs the data to your Fitbit account. Whether online or through the Fitbit App, you can set goals and stay motivated to keep on your path to fitness. You can compare your data with friends and family and even provide an encouraging message to spur them on. Your statistics can be wirelessly uploaded via a computer or smartphone, so you'll know in real time when you've reached one of your fitness goals. Batteries included.
