If you connect more than 1Fitbit device to the same account, note the following:

  • If you forget to take off one Fitbit device before putting on another, the overlapping data is reconciled to present the most accurate information possible. For best results, don't wear more than one device at a time and sync each device before taking it off and putting on another.
  • Only one person can use a Fitbit account. When you create a Fitbit account you’re asked for personal information, such as height and weight, to calculate certain data.
  • If you have more than one Fitbit device that receives notifications from your phone, notifications appear on one or more of your Fitbit devices.
  • A Fitbit device can only be paired to 1 phone. If you have more than 1 phone, you only receive notifications from the phone connected to your Fitbit device.

If you're unsure which scale you own, turn the scale over and remove the battery cover to see how many batteries it contains:

  • Aria uses 4 AA batteries
  • Aria 2 uses 3 AA batteries and has “Aria 2” written on the back of the scale
  • Aria Air uses 3 AAA batteries.

For more information about using your scale, see How do I use my Fitbit scale?

Aria connects to your wireless home network and works with any Wi-Fi router that uses the following standards:

  • 802.11b frequency setting
  • WEP / WPA / WPA2 personal security
  • Automatic (DHCP) IP setup (static IP configurations are not supported)

Your SSID and password should contain only alphanumeric characters (e.g. A-Z, 0-9). If you experience issues connecting to a network that uses special characters, change the name of the network to only use alphanumeric characters, and try to connect again.

A mobile Wi-Fi hotspot should only be used if a wireless router is unavailable. Consider the following information when attempting to set up your scale using a hotspot:

  • Connecting Aria to a mobile Wi-Fi hotspot requires that the mobile device be persistently in this mode. The device’s battery may drain quickly.
  • To complete the setup process with a mobile Wi-Fi hotspot, you will need a second wireless device to connect to the hotspot. For example, if you are using an iPhone as a hotspot, you will need either another mobile device or a computer to proceed through either of the set up methods explained in How do I set up Aria?
  • Your hotspot needs to be configured according to the same specifications as a wireless router. For the specs, see What router settings do I need to set up and sync Aria?

To set up your scale using the web-based method, you'll need a Wi-Fi enabled computer, phone, or tablet. Make sure you know your Wi-Fi password and that it doesn't exceed 31 characters. For help finding your password, see How do I find my Wi-Fi network password and security setting?

Note: If you're trying to set up your Aria again after making changes to your network, see How do I use my Fitbit scale?

To set up your Aria scale:

  1. Restart the computer, phone, or tablet that you're going to use to set up your scale.
  2. Make sure your browser allows cookies.
  3. If you're using a computer:
    1. Place your scale within 10 feet of your router.
    2. Ensure that your router is compatible with the 802.11b protocol. For more information, see What router settings do I need to set up and sync Aria?
    3. If the router is connected to your computer with an Ethernet cable, unplug it. The router and computer must be connected over Wi-Fi.
  4. Open a web browser on your computer, phone, or tablet and go to fitbit.com/scale/setup/start.
  5. Tap Get started, then tap it again when you see the pop-up message.
  6. Sign in to your fitbit.com account.
  7. Personalize your Aria by giving it a name and entering the initials you'd like to see on the scale when it recognizes you.
  8. Put the scale into setup mode by removing a battery for 10 seconds and then reinserting it. Tap Continue when the scale's display says "SETUP ACTIVE."
  9. Switch your computer, phone, or tablet to the scale's Wi-Fi network (this will appear as the word "Aria" followed by six characters).
  10. Return to your web browser and tap I'm Connected. You'll see a list of available wireless networks.
  11. Tap the name of your home wireless network. If you don't see your home wireless network, tap Refresh Networks to scan again. If you still don't see your network, tap Join Other Network to enter your network name and password manually.
  12. Enter your network password. Remember that it's case-sensitive.
  13. Tap Submit, and then immediately check your scale's screen as it attempts to connect to your network.

To set up your Fitbit Aria 2, create a Fitbit account and connect your scale through the Fitbit app on your phone.

If you already have a Fitbit account and the Fitbit app, skip to How do I add a scale to my existing account?

Aria 2 connects to your wireless home network and works with any Wi-Fi router that uses the following standards:

  • 802.11b/g/n frequency setting
  • WEP / WPA / WPA2 personal security
  • Automatic (DHCP) IP setup (static IP configurations are not supported)
  • Both the network name and password must be no more than 32 characters long

We do not recommend using a mobile Wi-Fi hotspot to set up Aria 2, as syncing will be slow and your scale may be unable to update. Connecting Aria 2 to a mobile Wi-Fi hotspot requires the device to remain persistently in this mode, which may drain the battery quickly and use excessive data.

Note: If you're trying to set up your Aria 2 again after making changes to your network, see How do I use my Fitbit scale?

  1. Make sure the Fitbit app is compatible with your device by checking fitbit.com/devices.
  2. Download and install the Fitbit app from one of the following locations:
  3. Open the Fitbit app and tap Join Fitbit to get started.
  4. Follow the on-screen instructions to create a Fitbit account and connect your scale to the internet. You must know your wireless network password, and the scale must be within range of the network. If you see an error message, see How do I use my Fitbit scale?

Note that the personal information you provide during setup is used to calculate your basal metabolic rate (BMR), which helps determine your estimated calorie expenditure and your body mass index (BMI). For more information, see How does my Fitbit device calculate my daily activity? This information is private unless you change your privacy settings and opt to share it with your Fitbit friends.
