Syncing your iPhone with your Fitbit gives you access to all sorts of fun information like:

Sleep zone monitoring
Health Metrics
Free workout videos
Advanced fitness goal tracking

Whether it's your first Fitbit or your tenth, you'll have to take similar steps to sync it to your iPhone. We'll walk you through each of those steps, and even show you how you can turn your iPhone into a secondary Fitbit.

If you already have a Fitbit account and an application installed on your iPhone, then you can skip to step 2.

If you haven't set up a Fitbit previously on your iPhone, then follow the steps below to sync your new Fitbit to your iPhone.

Plug your Fitbit device into the charger.
In the Apple app store, download and install the Fitbit app on your iPhone.
Open up the app and press Join Fitbit.
Follow the on-screen instructions to set up your new account profile.
Pair your Fitbit device with your iPhone's Fitbit app.

Make sure to grant the Fitbit Bluetooth and Location permissions when prompted to do so. You can always do this later by going to Settings, scrolling down to Fitbit, and allowing it access.

Your new Fitbit is now paired with your iPhone and will sync periodically to reflect your activity.

You can now skip to step 3 to see how to further sync your iPhone with your Fitbit account.

If you'd like to sync a new Fitbit device to your Fitbit account in your iPhone's app, then follow the steps below.

Plug your new Fitbit device into the charger.
From the Fitbit app, select the profile picture at the top-left of the screen.
Select Set Up a Device.
Scroll to select which new Fitbit device you are syncing.
Follow the on-screen instructions to switch to your new device.

The syncing process will take some time and may remove any older device you have associated with your profile (depending on the model). Once completely synced, you should see the new device listed on your profile page.

If you're giving your old Fitbit device to a new user, then you want to reset the Fitbit's settings.

Let's say your Fitbit is charging, but you still want to log your steps (and other non-biometric data). You can turn on "MobileTrack" in your iPhone's Fitbit app to make this happen.
