The Fitbit Alta uses Bluetooth connectivity to sync with phones. While reliable, many people have issues with Bluetooth for one reason or another, which results in syncing problems.
For most sync issues, you either have to restart the Fitbit Alta or pair the smartwatch with the device again.
We have the complete rundown on issues linked with syncing the smartwatch to your phone and how you can resolve them.
Why Won’t My Fitbit Alta Sync?
There are many reasons why your Fitbit Alta might not properly sync with your smartphone.
The most common of which are:
- Bluetooth is turned off.
- The smartwatch is not within the range of the device it is synced with.
- The Fitbit app crashes and needs to be rebooted.
- The smartwatch needs to unpair and sync with the device again.
The list of sync issues goes on. It may be difficult for some to diagnose the exact problem.
This is why we have listed a solution for all. This way, you can try them out until you find the right solution.
Most people will be pairing their Fitbit Alta with either an iPhone or an Android device.
We highlight the process of how to do that the first time and also troubleshoot when the smartwatch has issues pairing anytime after that.
Fitbit Alta Won’t Sync, What To Do?
iPhone and Android users sometimes have trouble connecting their phones.
But the Fitbit Alta is compatible with iPhone and Android and after manually pairing it once, it stays paired.
1. Syncing Fitbit Alta For the First Time
Let’s start from the top and make sure you are connecting your device properly.
iPhone: You will need to manually connect the smartwatch to your iPhone.
To do this, you need to:
- Open the phone’s setting app.
- Tap “Bluetooth.”
- If turned off, turn it on.
- A list of available Bluetooth devices will appear. Look for the Fitbit Alta and click on it.
Android: The process of fixing Fitbit Alta syncing problems with an Android is the same as an iPhone.
However, the steps slightly differ.
- Open the Settings app.
- Click on “Connections” and then “Bluetooth.”
- Find the Fitbit Alta in the list of devices and click on it.
The smartwatch should pair with the phone.
If it doesn’t for one reason or another, you can restart the Fitbit App or unpair and pair the two devices again.
2. Update your Phone
Before we begin figuring out what’s wrong with the Fitbit and the app, it won’t hurt to check whether your phone has any pending updates available.
That might as well be the cause of the issue.
Simply go to your phone settings and search for any available updates.
3. Reboot your Phone
This is another very effective and easy thing to test out. You can perform a so-called “soft reset” by pressing the volume up key and the power button simultaneously for about 15 seconds.
This is a great way to reboot your device without losing any data.
After the reboot is complete, try syncing your Fitbit Alta one more time.

If your Fitbit Alta still has trouble syncing after you’ve tried all the methods mentioned above, you may need to reset the watch.
