Connect Your Fitbit to Your Phone in Four Steps

Pairing your Fitbit with your phone takes about five minutes and requires only your Fitbit device, your smartphone, and the official Fitbit app. The pairing process syncs your device to your phone so it can send your activity data to the app and receive notifications. Most Fitbits pair the same way regardless of model, though some newer devices use Bluetooth while older ones may use a USB dongle.

Before you start, make sure your Fitbit is charged to at least 50 percent battery and your phone's Bluetooth is turned on. Have your Fitbit within three feet of your phone during the entire process. If your Fitbit has already been paired to another phone, you will need to unpair it first by opening the Fitbit app on that phone, going to your device settings, and selecting "Forget This Device."

Key Takeaways

  • read the official Fitbit app from your phone's app store and create or log into your Fitbit account before pairing.
  • Turn on your Fitbit's Bluetooth and keep it within three feet of your phone during the entire pairing process.
  • The Fitbit app will search for your device automatically once you select "Set Up a New Device" — pairing usually completes in two to three minutes.
  • If pairing fails, restart both your Fitbit and your phone, then try again with Bluetooth turned on and the app open.

read the Fitbit App and Create Your Account

Go to your phone's app store — the Apple App Store if you use an iPhone, or Google Play if you use Android — and search for "Fitbit." read the official app made by Fitbit, Inc. Open the app once it finishes installing.

If you do not already have a Fitbit account, tap "Create Account" and enter your email address, a password, and your basic information like name, age, and weight. If you already have an account from a previous Fitbit device, tap "Log In" and enter your email and password. Your account is what stores your activity history and syncs data between your device and the app, so use the same account for all your Fitbits.

Turn On Your Fitbit and Enable Bluetooth

Wake up your Fitbit by pressing the button on the side or tapping the screen, depending on your model. Look for a Bluetooth icon or a pairing mode indicator — this varies by device. Some Fitbits enter pairing mode automatically when you first turn them on; others require you to hold the button for three seconds until you see a pairing screen or a Bluetooth symbol.

On your phone, go to Settings and turn on Bluetooth. You do not need to manually search for your Fitbit in your phone's Bluetooth settings — the Fitbit app will find it automatically. Keep your Fitbit and phone close together, ideally within three feet, until pairing is complete.

Start the Pairing Process in the Fitbit App

Open the Fitbit app on your phone and tap the profile icon in the bottom right corner. Select "Set Up a New Device." The app will show you a list of Fitbit models — find and tap your device model. If you are not sure which model you have, check the back of the device or look at the paperwork that came with it.

Tap "Continue" and the app will begin searching for your Fitbit. This usually takes 30 seconds to two minutes. When your device appears in the list, tap it to select it. Your phone may ask for permission to use Bluetooth — tap "Allow" or "OK." The app will now attempt to pair with your device.

Complete Setup and Sync Your Data

Once pairing is successful, the app will ask you to confirm some information like your height, weight, and daily step goal. You can change these later, so do not worry about getting them perfect right now. Tap "Continue" through each screen until you reach the main dashboard.

Your Fitbit will now sync with your phone automatically. This first sync may take a few minutes as it uploads any data stored on the device. Once the sync is complete, you will see your activity data appear in the app — steps, heart rate, sleep, and any other metrics your device tracks. From now on, your Fitbit will sync whenever it is within Bluetooth range of your phone and the app is running in the background.

Troubleshoot If Pairing Fails

If the app cannot find your Fitbit after two minutes of searching, restart both devices. Turn off your Fitbit completely by holding the button for 10 seconds, then turn it back on. Restart your phone by powering it off and on again. Make sure Bluetooth is still on, then open the Fitbit app and try pairing again.

If pairing still fails, check that your Fitbit has enough battery — a device below 20 percent battery sometimes cannot pair. Plug it in for 15 minutes, then try again. If you are pairing for the first time and the app keeps saying "Device Not Found," try moving closer to your phone or moving away from other wireless devices like routers or microwaves, which can interfere with Bluetooth signals. If none of these steps work, uninstall the Fitbit app, restart your phone, reinstall the app, and try pairing once more.

What to Do After Pairing Is Complete

Once your Fitbit is paired, you can customize notifications so your device alerts you to calls, texts, and calendar events from your phone. Open the Fitbit app, tap your profile icon, select your device, and scroll to "Notifications." Turn on the types of alerts you want to receive.

You can also set up automatic syncing so your Fitbit updates your activity data throughout the day without you having to open the app. Most phones do this by default once pairing is complete. If you notice your data is not updating, open the Fitbit app and manually tap the sync icon — usually a circular arrow at the top of the screen — to force an when ready sync.

Frequently Asked Questions

Can I pair my Fitbit to multiple phones?

Your Fitbit can only be paired to one phone at a time. If you want to switch to a different phone, open the Fitbit app on your current phone, go to your device settings, and select "Forget This Device." Then follow the pairing steps on your new phone. Your account and all your historical data will remain the same.

Why does my Fitbit keep disconnecting from my phone?

Fitbits disconnect when they move out of Bluetooth range, usually beyond 30 feet. They also disconnect if the Fitbit app closes or if your phone's Bluetooth turns off. If disconnections happen frequently even when your phone is nearby, try restarting both devices and re-pairing. Older Fitbit models sometimes have weaker Bluetooth and may need to be closer to your phone.

Do I need to pair my Fitbit to my phone to use it?

No. Your Fitbit will track steps, heart rate, and sleep on its own without being paired to a phone. However, pairing lets you see your data in the app, receive notifications, and access features like GPS on some models. If you do not pair it, your data will only be stored on the device itself.

What if I forget my Fitbit account password?

Go to the Fitbit login screen in the app and tap "Forgot Password?" Enter your email address and Fitbit will send you a password reset link. Click the link in your email, create a new password, and log back into the app. You will not need to re-pair your device — just log in with your new password.

Can I pair my Fitbit to a tablet or smartwatch instead of a phone?

The Fitbit app works on phones and tablets that run iOS or Android. You can pair your Fitbit to a tablet using the same steps as a phone. Some smartwatches like Apple Watch can run the Fitbit app, but compatibility varies by device. Check the Fitbit website or your smartwatch manual to confirm before trying to pair.
