Few things are more frustrating than when your Fitbit won't sync, whether you have a Versa, Charge, Inspire or Ionic.

In this guide, we'll be walking through exactly how to sync your Fitbit, and what to do when it's having trouble syncing. After all, most users are likely to come across issues over time.

Syncing a Fitbit to your phone or computer means that any data being stored on the device is transferred over to the Fitbit app. It's from here that you're able to go more in-depth and check back on historic data. So, you can see how not being able to sync is a big problem.

Below, we'll explain everything there is to know about Fitbit syncing.

How to sync Fitbit

Syncing with your Fitbit should actually be very straightforward, which is why it can be pretty head-scratching when your data doesn't seem to be transferring.

Once your Fitbit is set up and connected to your phone, it should have a consistent Bluetooth connection to it and therefore be ready to link up whenever you open the Fitbit app.

How to manually sync your Fitbit

If you want to force your Fitbit to sync, simply swipe down from the Fitbit app's home screen and release to begin the process. You should then see the turquoise line worm its way from left to right just above the main tracking panel.

Turn on All-Day Sync on Fitbit

If you have the app running in the background, you can turn on All-Day Sync by tapping on the device icon in the top-left and scrolling down to the All-Day Sync tab, which will mean syncing is performed automatically throughout the day.

How to sync Fitbit with a computer

You don't need a smartphone to sync Fitbit data, which will be music to the ears of people without shiny new phablets. If you have a feature phone, or just don't want that Bluetooth connection, you can sync your Fitbit straight to a PC. We're going to assume your Fitbit has been registered and set up properly, but there's a catch - to use Fitbit Connect, you need the Fitbit Wireless Sync Dongle.

1. Download Fitbit connect.
2. Make sure you're signed in with your account credentials.
3. Connect your Fitbit Wireless Sync Dongle.
4. It should sync automatically, or you can press Sync to do it manually.
5. Log into the Fitbit Dashboard at

It should be as simple as following the above, but experience tells us that it's fairly likely you'll come across some kind of issue with Fitbit syncing from time to time.

Some of the minor hiccups resolve themselves, while others require a bit of digging around. Be aware that these troubleshooting tips do vary slightly depending on the connected device, but whether your Fitbit is linked to an Android smartphone, iPhone or tablet shouldn't make too much difference.

Problems with syncing are usually because you're not filling a requirement. Here's a checklist of the very basic things to double check if your Fitbit isn't syncing.

Fitbit syncing troubleshooting tips

  • Check the Fitbit app is compatible with your device here, and that it's running the latest version (if on iPhone or Android, check for this through the App Store or Google Play Store).
  • Your connected device is running the latest software.
  • Your connected device has a cellular data or Wi-Fi connection.
  • Your connected device has Bluetooth turned on, and that you aren't connected to multiple things (some issues are related to conflicting Bluetooth connections).
  • Your Fitbit device's battery isn't low.
  • Your Fitbit device's software is up to date.

This list should be your starting point for if you're experiencing consistent issues with syncing, but, if all these are ticked, it's time to start troubleshooting with the tips below.

  • Perform a hard reset of the Fitbit app.
  • Turn Bluetooth off/on.
  • Turn your Fitbit off/on.
  • Uninstall and reinstall the Fitbit app.
  • Try logging into your Fitbit account on another device.
  • Remove other Fitbit devices from app and Bluetooth list.

If none of the above work for you, also consider factory resetting your Fitbit and completely restarting the Fitbit setup process. This will result in any un-synced data being lost, but it could be the ticket to a world without syncing problems.

    For Android 6.0 (Marshmallow) and later Location and Bluetooth both need to be enabled for successful syncing. This is a Google issue and it's kind of annoying. If you're worried about battery life on your phone you don't need to have these on all day (unless you want to do the all-day syncing), just turn them on the moments you actually want to sync.
