Hello @Theresejoe have a warm welcome to the Fitbit Community, it's great to have you on board. 

I appreciate your participation in the Forums and for sharing your experience with us. Tell me, have you restarted your phone and your Ionic already by pressing and holding the Back and Select buttons (left and bottom right) until you see the Fitbit logo on the screen? If so, I would like to suggest you to check the following steps:

• Make sure the software on your mobile device is up to date. To check, tap Settings > General > Software Update.
• Make sure there are no other Bluetooth devices around as they might interfere with the syncing process
• Check that your Fitbit device's battery isn't critically low.

If your device still won't sync, try these steps:

1. Force quit the Fitbit app. 
2. Go to Settings > Bluetooth and turn Bluetooth off and back on.
3. Open the Fitbit app.
4. If your Fitbit device didn't sync, restart your phone again.
5. Open the Fitbit app.
6. If your Fitbit device didn't sync, restart it one more time.
7. If your Fitbit device won't sync after the restart, log in to your Fitbit account on a different phone, tablet, or computer and try to sync.
8. If your Fitbit device still doesn’t sync, remove all other Fitbit devices from your account and from the list of connected Bluetooth devices on your mobile device and try to sync.

Give these steps a try and let us know the outcome!
