Troubleshooting steps

Force quit and then reopen the Fitbit app.

Turn your phone or tablet off and back on.
Uninstall and reinstall the Fitbit app.
If your Fitbit scale won't sync after you reinstall the app, log in to your Fitbit account on a different phone or tablet and try to sync.
If your Fitbit scale still doesn't sync, remove all other Fitbit devices from your account and from the list of connected Bluetooth devices on your phone and try to sync.

Aria & Aria 2

After weighing in on Fitbit Aria or Fitbit Aria 2, the scale should display a progress bar, followed by a check mark, which indicates the new measurement synced successfully.

If the scale doesn't sync, you may see one of the following error messages on the scale's screen:

NO SYNC
WIFI Symbol with an "X"
WRONG PASSWORD
CONNECTION ERROR
CAN'T CONNECT
NO WIFI
WEAK SIGNAL
No error message, but the measurement doesn't sync to your Fitbit account

If any of these conditions occur, try weighing yourself again. If the scale successfully syncs, it may have been a temporary issue that doesn't require further troubleshooting. If the problem persists, try the following tips:

Check that your router is on and working. If other devices are also unable to connect to your Wi-Fi network, restart your router.
Remove the batteries from your scale for 10 seconds, then reinsert them to restart your scale.
If you've made any changes to your network, such as a new router, network name, or password, see How do I reconnect my Fitbit scale to my wireless network?
Your scale may be too far away from your router. Several walls, floors, or objects between the scale and router can cause interference. Try moving the scale closer to your router.
The network may have too much traffic or there are too many other Wi-Fi networks nearby. Don't use public Wi-Fi to sync your scale.

If you still can't sync, contact Customer Support. For additional information on error messages, see Why isn't my Fitbit scale working?
