How to pair your Fitbit to your phone or tablet

Your Fitbit uses Bluetooth Low Energy (BLE) technology to pair and sync with your iPhone, Android, and other devices. Once you initially pair your Fitbit to your mobile phone, it automatically syncs with the app and your online account throughout the day. Plus, you’ll also see your text messages and notifications on your Fitbit (if you set up this feature.)

That’s why it’s so important to correctly pair your Fitbit before you start using it.

Want to connect more than one Fitbit to your account?

If you share a single Fitbit account with your partner, family, or friends and want to connect more than one Fitbit device to that account, you may be limited.

At this time, you can only connect one of these models at a time to your account: Fitbit Charge 3/4/5, Fitbit Ionic, Fitbit Inspire series, Fitbit Luxe, Fitbit Sense series, and Fitbit Versa series. Each of these Fitbit models requires a unique Fitbit account (username.) 

You can, however, connect an older device like the Fitbit Alta or Charge 1/2 and a newer Fitbit like the Versa 3 to the same Fitbit account.

If you’re replacing a Fitbit with the same model, follow the steps in this article instead: Got a new or replacement Fitbit? How to set it up, so you don’t lose data.
