Last Updated: June 24, 2020 Tested

Your Fitbit Flex can monitor your workouts and physical activity, providing an easy-to-access log of your fitness routine. The Flex does not have any display or interface, so you'll be setting it up using a program on your computer or app on your mobile device. You'll need to create a free Fitbit account during the setup process to use your Fitbit.

Setting up Fitbit on a Computer

1
Visit the Fitbit Connect download page. You can download the Fitbit Connect program for Windows or Mac by visiting fitbit.com/setup. This program will track your Fitbit information.
2
Download the installer for your operating system. If you scroll down the page a little, you should see a button for downloading the setup program. The website will attempt to detect your current operating system and provide the correct link. If the wrong button is showing, select your operating system underneath the Download button.
- Note: If you're using Windows 10, the Download button will take you to the Windows Store. Windows 10 uses the same app as the Windows Phone, so follow the method below after installing it. If you'd prefer to use the traditional Windows program, select "PC" as your operating system.
3
Run the downloaded installer to install Fitbit Connect. Once the download is finished, run the installer and follow the prompts to install Fitbit Connect on your computer.
4
Run Fitbit Connect and select "New to Fitbit." This will allow you to create a new Fitbit account and setup your device.
- Note: If you have a previous Fitbit account, select "Existing User" to sign in with your existing account and setup your new Flex.
5
Create a Fitbit account. You can enter in an email address and create a password, or you can sign in using your Facebook or Google account.
6
Enter your personal information. Fitbit will use this to help track your performance. Enter your name, gender, birthday, height, and select your time zone.
7
Select "Flex" from the list of devices. This will allow you to start setting up your Flex.
8
Insert the tracker back in the wristband. Insert it into the wristband with the arrow facing out and pointing towards the black band.^{[1]

9
Put the bracelet on. Attach the wristband to your wrist using the clasp. The wristband should be snug but not constricting.
10
Insert the USB Bluetooth dongle into a USB port on your computer. You won't be able to continue with the Setup process until it's been inserted.
- This isn't required for computer's that already have Bluetooth capability.
11
Wait while your Flex tracker pairs with your computer. It may take a moment for your computer to find your tracker.
12
Tap the flat part of your Flex twice when two lights appear. Once the tracker has connected, you'll see two indicator lights on the black band. Tap your wristband twice and you'll feel the tracker vibrate.
13
Start using your Flex. Your Flex is now setup, and the initial goal of 10,000 steps will start. You can check your progress by double-tapping your Flex. Each light indicates 20% of your goal.
14
Visit your dashboard. Once your device is synced, you can view your data from your Fitbit dashboard. You can use this to log activities, food, and track your progress towards your goals. You can open your dashboard any time at fitbit.com/login using your Fitbit account.

9
Pair your device. Follow the prompts to pair your Fitbit tracker with your mobile device.
- Note: If you're using the Windows 10 app on a computer that doesn't have Bluetooth, you'll need to insert the USB Bluetooth dongle.

Troubleshooting

1
Make sure you have at least a 60% charge. Plug your tracker into the charger and make sure at least three of the lights are on. For best results, charge it until all five lights are on.
2
Try restarting your tracker if you can't pair or sync. If your tracker stops functioning properly, a reset will usually fix it. This won't delete any of the data on the tracker.
- Plug the USB charging cable into a USB port.
- Insert the tracker into the charging unit.
- Use a paper clip to press and hold the pin hole on the back of the charger for about four seconds.
3
Restart the setup process if it doesn't pair. If the setup process fails, you may want to try again from the beginning. Uninstall the Fitbit Connect program or app and then download and install it again. Follow the prompts to try setting up your device.
4
Try another device. If you can't get your Fitbit to connect to your computer, try setting it up with a mobile device, or vice-versa.
