Fitbit One Wireless Activity and Sleep Tracker - Black

Before you put on your Fitbit  tracker and get moving, you must connect it to your mobile device or computer. Connecting your tracker (also known as pairing) makes sure it can transfer data back and forth with Fitbit (known as syncing). Your tracker data syncs to your Fitbit dashboard, which is where you can see your stats, analyze historical trends, set goals, review your exercise history, log food and water, challenge friends, and much more.

If your tracker has one of the following problems, it may be fixed by a restart:

• Your tracker isn't syncing
• Your tracker isn't responding to button presses, taps, or swipes
• Your tracker is charged but doesn't turn on
• Your tracker isn't tracking your steps or other stats

For restart instructions, choose your tracker below.

Note: Restarting your tracker turns it off and on without deleting any activity data. If your tracker saves notifications, a restart deletes them.

1. Plug your charging cable into your computer.
2. Plug your Fitbit One tracker into the charging cable, making sure that the gold contacts on your tracker align with the gold contacts in the inside of the charger.
3. Hold down your tracker's button for 10-12 seconds.
4. Remove your tracker from the charging cable and press its button until the screen turns on.

Your tracker should now work normally. If your tracker still doesn't work after a restart, contact Customer Support.

If you can't get started with your Fitbit tracker, usually a missing requirement is the cause. Please click here for further guidance on how to resolve your issue. 

Make sure you see an alarm screen when you press the button to move through the screens. This means you've created and synced the alarm.

Next, test your tracker's vibration motor.

1. Plug your charging cable into the USB port on your computer.
2. Clip the other end of the cable into the port on the back of your tracker. Your tracker should vibrate when you connect the cable.

Use the timer on your Fitbit One to track a specific activity in greater detail. For example, if you put your tracker in exercise mode and go for a walk or run, when you sync your tracker after your exercise you’ll see a new entry on your fitbit.com activity log. The entry provides a summary of the activity's stats as well as a minute-by-minute graph.

To track an exercise:

1. Hold down the button until you see the timer start. While your tracker is recording an activity, its icons will blink continuously and you will see a stopwatch for the duration of the activity.
2. When you're done with your workout, hold down the button until you see the timer stop.
3. Sync your tracker.
4. Log into your fitbit.com dashboard and go to Log > Activities to see the activity. Note that you can't view activity details from the One in the Fitbit apps.

If your battery isn't charging, test the solutions below. If your battery is draining too quickly after a charge, see Can I improve my tracker's battery life?
