The Aria can be set up for eight different accounts on the Fitbit website.
To invite others to use your scale, please do the following:
- Go to the Devices page at http://www.fitbit.com/settings/device.
- Select the scale icon and click "Invite People."
- Enter email addresses and click "Send Invite."
When two or more registered Aria users are close in weight, the scale will recognize this and after showing a user's weight, the Aria will display initials on the scale. If the initials shown are not correct, tap the scale until the appropriate initials appear. The scale will then assign the measurement to the correct person.
