How to Fix Fitbit Won’t Sync Issues in 2021, Troubleshooting Ways

Can’t sync your Fitbit Sense or Versa Series watch with your mobile phone, tablet, or system? Then you are not alone. A recent update has caused syncing issues for several users.

We also experienced this frustration as Fitbit owners! Therefore, our goal here is to offer assistance, which will hopefully make your Fitbit, whatever its model, sync again!

Why is my Fitbit Won’t Sync with the Fitbit application on mobile devices? 

Sadly, it’s not uncommon for your Fitbit to stop syncing with the app, especially if you have updated the Fitbit app recently or updated your Fitbit’s firmware.

A recent update may have broken your Fitbit, so if it doesn’t sync or connect as it used to you have a few options before contacting Fitbit.

What data is syncing between my Fitbit and my mobile? 

When your Fitbit syncs, your health and fitness data is transferred from the device to your phone. Heart rate information, sleep metrics, exercise minutes, and so on.

Your Fitbit device data syncs to your Fitbit dashboard, so you can review this data on any other device or computer with the Fitbit app or log in to your Fitbit account online.

Bluetooth Low Energy (BLE) technology is used by most Fitbits to sync with your phone, tablet, and some computers. Rather than using Bluetooth, the Fitbit Aria and Fitbit Aria 2 use Wi-Fi.

Close the Fitbit App

Syncing the Fitbit again is as simple as restarting the Fitbit app. You must force close the app and then reopen it.

Force close application on Apple iOS or iPadOS

  • You can access the app switcher by swiping up from the bottom of your screen to the middle or by double-pressing the home button. Choose the Fitbit app and swipe it up from the top of your screen.

Force close app on Android

  • Click Settings > Apps or Apps & Notifications > Tap the Fitbit app > Force Stop and confirm OK.

Open the Fitbit app again and make sure you’re Fitbit Versa or other model is turned on and in area.

If the Fitbit is syncing, you should see a progress bar in the top left-hand corner.

Reinstall the app

If closing and restarting the Fitbit app didn’t help, try deleting and reinstalling it via the App Store or Google Play Store.

You lose any data that has not yet synced with your Fitbit account when you delete the app. All other data since the last sync remains in your account and will not be automatically deleted.

Check for updates

As I have seen over the years, people forget to update their applications properly.

There are times when you may think an app will work forever, but those “bug fix” releases are essential.

Whether you own an iOS or Android device, you can access the App Store/Play Store.

Check for updates and download them if needed.

You should also make sure that your smartphone is properly updated. Here are the steps for iOS:

  1. Open Settings
  2. Select General
  3. Scroll down and select Software Updates

Here are the steps for Android users:

  • Open Settings
  • Scroll down to System
    • You may also need to tap Advanced
  • Tap System Update
  • Tap Check for Update

There may be compatibility issues if an update is available for your smartphone. It is extremely important to keep your app and your phone up to date.

Reboot the Fitbit device

Rebooting your Fitbit is also one of the easiest ways to get everything working again.

It is pretty simple to do, and is similar to the adage “unplug it, then plug it back in.”

To restart your Fitbit through the watch’s Settings app, follow these steps:

  • Navigate to your Fitbit’s clock face.
  • Open the Settings app, and select about.
  • Then tap Shutdown or Reboot.
  • Click to confirm to shut down your device.
  • Wait 1 minute and turn your Fitbit or different model back on.

People with problems have found this method to be one of the most helpful.

Toggle Bluetooth off and on

To rule out Bluetooth as the cause of your syncing issues, you’ll want to toggle the feature on and off.

There is no way to completely disconnect the Fitbit from your smartphone, but this can help provide a “jolt” to try to get syncing to work again.

Unpair or Skip your Fitbit from Bluetooth, then re-pair it.

Fitbit also suggests removing the Fitbit from paired Bluetooth devices in rare cases. Here are the moves to do so on iOS:

  1. Open Settings or Settings > Connections
  2. Select Bluetooth
  3. Tap your Fitbit’s name
  4. Scroll down and choose Unpair or forget this device.

Instead of pairing your Fitbit through the Bluetooth settings, open the Fitbit app instead.

It also ensures that your Fitbit and smartphone are communicating during the pairing process.

Check Always Connected and All-Day Sync

If you run an older version of the Fitbit application on your Android or Apple device, you might need to turn on a few additional settings, Always Connected and All-Day Sync.

Recent Fitbit app versions don’t include these options, but if you can’t update or don’t want to, check out these settings.

A few new features have been added to Fitbit’s app that helps keep your devices connected. There are two of them: Forever Connected and All-Day Sync.

By default, these are turned on but ensure that your Fitbit data is synced with your smartphone.

This is even true if you don’t regularly check the Fitbit application but still want your Versa or other Fitbit model data to sync.

In the top right corner of the app, tap the Fitbit icon to see whether this is enabled. Smartwatches and fitness trackers have specific settings.

In the bottom of the page, you can toggle between Always Connected and All-Day sync. Try turning them on and then closing the Fitbit app if they are not turned on. You may be able to get your Fitbit back to working order by following these steps.
