Meet Zip.


Get a kick out of fitness with this little device. It tracks your steps, distance, and calories burned – and syncs those stats to your computer and select smartphones. In doing so, it celebrates how much more you do each day. Zip encourages you to set goals, challenge friends, and go farther – one step at time. That’s how you turn everyday life into a social, achievable, awesome path to fitness.

Built to keep you moving

By showing you how your day is stacking up, Zip encourages you to get up and go…and keep going! It helps you make those small changes that can add up to something big. (No wonder Fitbit users average 43% more steps each day.)



Powered by Fitbit’s leading-edge accelerometer, Zip accurately captures all-day activity that old-school pedometers can’t handle. It bases calculations like calories burned on your personal profile – reflecting your stats, not any average Joe’s.

Wireless sync to PC and Mac

  • Fitbit’s trackers are the first all day activity trackers to offer Bluetooth Low Energy connectivity, so you see your stats in real-time.
  • Syncing occurs automatically any time Zip is within about 20 feet of the wireless sync dongle and is relatively motionless. The dongle plugs into your Mac or PC’s USB port. Syncing and uploading require use of the Fitbit uploader application.

Wireless sync to mobile

Syncing Zip to your smartphone or tablet requires Bluetooth Low Energy. This allows your Zip to sync wirelessly and automatically with a wide range of leading iOS and Android Smartphones.

If your phone does not support Bluetooth Low Energy, you’re still in luck.

The Fitbit mobile app works with all smartphones for logging data, receiving notifications, and viewing graphs and charts based on your last sync.



We recommend syncing your data regularly. As long as Zip has minimum battery power, it tracks up to seven days of detailed, minute-by-minute data. For the preceding 23 days, it summarizes your daily calories, distance and steps taken.

Batteries and Power

The battery inside Zip lasts four to six months. It has a low battery indicator on the LCD screen. To change your battery, use the battery door tool to unlock and open the door. Remove the battery, place the new battery into the cavity, and close the door.
