Using your Fitbit Aria Scale

How it Works

The Aria will measure your weight and % body fat. Your BMI is calculated and viewable on your Fitbit.com account and in the mobile apps.

  • Weight data is uploaded through your chosen network to your account on Fitbit.com.
  • For greatest accuracy, the scale should be kept on a hard, flat surface. Use of Aria on carpet is not recommended and may result in inaccurate measurements.
  • To properly measure % body fat, you must be barefoot and balanced evenly between both sides of the scale. Stand with both feet pointed forward, not diagonally across the scale.

Batteries

  • The Fitbit Aria uses 4 AA batteries. A scale taking four measurements a day should last approximately six months.
  • The battery compartment is located on the bottom of the Aria.
  • When the batteries are low, you will be notified on your Fitbit.com Dashboard, on your Device Settings page, and by a low battery indicator on the scale's display.
  • When the batteries are dead, just replace them with new AA batteries. Low powered batteries may reduce the functionality of the scale.

Display

Icons

Display: Icons
  1. Progress bar: indicates progress of the scale in capturing weight and body composition.
  2. Sync: displays when the scale is connecting to the Fitbit server to sync your weight information.
    1. Wi-Fi Active: signals a connection with the Wi-Fi network.
    2. Wi-Fi error: signals a failed connection with the Wi-Fi network. If you see this icon please check your Wi-Fi's connection.
    NOTE: Your scale's internal memory will hold the last sixteen measurements, until the scale properly syncs.
  3. Battery low: shown when battery level is 26% or less. The scale will still work but it will not be able to update firmware until new batteries are placed.

Stepping on the Aria will show the following on the scale's display:

  • Weight
    Stepping on the Aria will show the following on the scale's display: Weight Stepping on the Aria will show the following on the scale's display: Weight
    • The weight units can be changed to display in pounds, kilograms or stone by going to your device settings at //www.fitbit.com/settings/device/scale.
    • To accurately track weight changes over time, try to weigh yourself at the same time each day. It is normal for your weight to fluctuate throughout the day.
  • % Body Fat
    Stepping on the Aria will show the following on the scale's display: % Body Fat Stepping on the Aria will show the following on the scale's display: % Body Fat
    • This reading will only be displayed after you connect your Fitbit.com account with the scale. If you weigh yourself before linking Aria to your Fitbit account, it will show weight but not have the required user information (height, age, gender) to give an accurate body fat reading.
    • A person must be barefoot to get a % body fat reading. Otherwise, the scale will display ?%, indicating that the scale is unable to take a users body fat measurement.
  • User's Initials
    Stepping on the Aria will show the following on the scale's display: User Initials
    • If the user has paired their Fitbit.com account to the scale, their initials should show after a measurement has been taken.
    • If the user has not paired their Fitbit.com account to the scale, or they are not recognized, then the word "GUEST" will be displayed after the weight measurement.

Notification Messages:

  • SENSING: Message indicates that Aria is gathering your weight information. Generally appears after a period of the scale being unused or when the batteries have been replaced.
    Notification Messages: SENSING
  • THINKING: The data gained while on the scale is being used to calculate weight and % body fat. This stage compensates for changes in the components of the scale, to provide the most accurate weight measurements.
    Notification Messages: THINKING
  • UPDATING: Indicates that the scale is receiving the most recent firmware. Firmware updates provide the latest features and improvements.
    Notification Messages: UPDATING
  • STEP ON: Aria has not had a sufficient amount of time to accurately calculate your weight, step back onto the scale and proceed weighing yourself normally.
    Notification Messages: STEP ON
  • STEP OFF: Aria has successfully gathered the necessary data to provide an accurate weight measurement. Please step off of the scale and wait for your measurement readout.
    Notification Messages: STEP OFF
  • Confirmation: The check-mark confirms that the last weight measured was successfully uploaded to the Fitbit server.
    Notification Messages: Confirmation

Syncing Your Measurements

  • The time of your most recent sync from your scale will show on your Fitbit Dashboard and on your Device Settings page.
    Syncing Your Measurements: Device Settings
  • Assuming a working Wi-Fi network, every measurement should upload to your Fitbit account, and is visible in your weight graphs and on the Device Settings page.
  • Weight and % body fat from your most recent measurement will show in the "Body" area of the Dashboard and in the Track Weight section.

Adding People to the Scale

How to add someone

  • Eight different accounts can be linked to an Aria at one time.
  • Anyone who is linked to the scale can invite others to join from the Fitbit.com Device Settings page: //www.fitbit.com/settings/device/scale or within the iOS mobile app.
  • Those invited will be sent an email inviting them to the scale. Upon accepting the invite, they'll have the option to either create a new account, or sign in with their existing Fitbit.com account.
  • Once a user accepts an invitation and links their account to the scale, the scale will be able to upload their measurements to their Fitbit.com account.
  • Even with multiple people using the scale, all assigned measurements will be private unless the user has changed their privacy settings to make them visible to friends or the public. If you're not sure what your privacy settings are, you can see them by going to //www.fitbit.com/user/profile/privacy.
  • All people who share a scale become Fitbit friends to one another, so if your weight is shared with friends, other people using the scale will be able to see your weight.
  • There is no "manager" or "owner" of the scale, if multiple accounts are linked. Accounts have equal ability to remove users and assign guest weights.

Assigning a Measurement

If two people linked to a scale are close in weight (+/- 8 lbs), the Aria will prompt you to select which person is being weighed. In the event the scale incorrectly recognizes a person, scale users have the option of reassigning the "Guest" weight to the correct person.

Assigning a Measurement: Dropdown
  • When an individual stands on the scale that is in a similar weight range as an existing user, the scale will display "Tap to Select User", then "Step Off". You should then step off the scale and watch the screen for your initials. If someone else's initials appear first, tap the scale to switch users. When you see your initials appear, wait until the progress bar disappears. The weight measurement will be assigned to you.
    Assigning a Measurement: One Assigning a Measurement: Two
  • When the scale does not recognize the user, it will display "GUEST" and show no body fat reading.
    Assigning a Measurement: GUEST
  • To assign an uploaded measurement to the correct person, go to your Device Settings page (//www.fitbit.com/settings/device/scale), and on the measurements tab find the weight. You can see whom the measurement is assigned to and reassign the measurement to another account, or to "Guest". When there are unassigned Guest weights, there will be an alert on your Dashboard. Anyone with an account connected to the scale will be able to assign a Guest weight to themselves.

Removing Users

  • Anyone who is linked to the scale can remove users from their scale via the Device Settings page: //www.fitbit.com/settings/device/scale.
  • To remove someone, locate the person on the "People" tab, hover over their name, and click the "X" to the right of their name.
  • Someone who is removed can be easily added back by sending another invite email.

Log Tab: Track My Activities

Log Tab: Track My Activities
  • Activity logging can be used to log any exercise. If you're also using a Fitbit Ultra, your Tracker will pick up most of your everyday activities, but you have the option to log those that it does not adequately track, such as weight lifting, cycling, yoga, or any other exercise activities where your body is relatively stationary.
  • If you're using a Fitbit Ultra, the information from any logged activity will overwrite anything your Tracker measured for that time frame. Manually logging an activity will not double-count any information picked up during that time.
  • You can create a custom activity by entering the activity name in the search box and clicking Create Custom Activity.
  • With the custom activity, you can manually enter the calories burned as displayed from a third-party device.
  • When you log the custom activity subsequent times, the site will automatically calculate your calorie burn based on what was entered previously.
  • As with food logging, you can mark your favorite activities by clicking the star to the right of the logged activity. It will then show up in your Favorites list for easy logging in the future.
  • The "Hide this day's calories" link can be used to hide a day's calories if you don't want them included in your graphs and statistics. The calories on historical graphs will show 0 for that day, and your weekly average and other stats will ignore that day.

Track My Weight

  • Your weight, % body fat, BMI and body measurement graphs are located on the weight tab. This includes week, month, year and full history views.
  • Your graphs will show you your trends over time and your entire history of weight information on Fitbit.

Changing the Wi-Fi Network for your Scale

To change the network your scale is connected with, you'll need to go through the setup process again.

NOTE: Someone who is already linked to the scale should change the Wi-Fi network. If a new person sets up the scale to change the network, the accounts already associated with the scale will no longer be linked.

  1. Begin the setup process by running the Fitbit installer software. If you haven't downloaded it yet, you can do so by going to www.fitbit.com/start and following the link for Aria setup.
  2. The setup process will begin. Sign in with your existing account.
  3. Remove one of the AA batteries from the battery compartment, wait ten seconds, then replace the battery to restart the scale. The scale will verify your current network settings and prompt you to "Tap to change Wi-Fi."
  4. When prompted to tap the scale, use your foot or a firm hand to press down on either side of the scale, near the lower half of the scale's surface. "SETUP ACTIVE" should appear on the scale's display.
  5. You have the option of keeping the existing scale name and user ID.
  6. Update the network to the one you want to use, and wait for the scale to connect.

Network issues

You can check your last sync time on the iPhone app and on the web Dashboard.

If the scale cannot reach the Wi-Fi network, the Wi-Fi error icon will light up on the bottom of the round display.

Firmware updates

The scale occasionally needs to update its firmware. Firmware updates provide new features and better functionality to the user. The updates will happen automatically. A firmware update will be indicated by the word “Updating” displaying after a weighing.

Lean mode

For most body types, the scale's regular setting will suffice. However, people with more muscle mass (e.g., a bodybuilder) have the option of choosing the "lean" setting from the Device Settings area: //www.fitbit.com/settings/device/scale. The "lean" setting provides a more accurate % body fat measurement for very muscular people, and will only apply to the account that has the option selected.
