Follow this quick checklist to help fix syncing issues with your Fitbit
- Take a look for any service disruptions at Fitbit. In particular, take a look at Device Sync / Pairing.
- If you use a new phone or tablet, first unpair your Fitbit from your previous phone’s Bluetooth and then try pairing and syncing with your new device. Fitbits can only pair directly to 1 device.
- Check that your Fitbit isn’t connected and syncing to another device, like your iPad, tablet, or even one of your family members’ devices.
- Try syncing manually by tapping your profile picture or icon > your Fitbit device > Sync Now.
- Turn off all other Bluetooth connections on your phone or tablet, and then try syncing with your Fitbit.
- Charge your Fitbit so it’s at least 60% battery availability, then try to sync.
- Update your Fitbit’s firmware and update the Fitbit app.
- Shut down and restart your Fitbit and then try to sync. Restarting does not delete any activity data.
- Force Close the Fitbit App on your phone, tablet, or computer, and then try syncing again.
- Forget the Fitbit from your phone’s Bluetooth Settings. Then, open the Fitbit app and wait for a message asking you to allow your Fitbit device to pair with your phone. Tap Pair to approve the request to re-pair it to your phone, tablet, or computer.
- For Android, try clearing the Fitbit app’s cache and/or delete use data.

Why is my Fitbit time not syncing with the Fitbit app on my iPhone or Android device?
Sadly, it’s not uncommon for your Fitbit to stop syncing with the app, especially if you updated the Fitbit app recently or updated your Fitbit’s firmware.
If a recent update impacted your Fitbit and it’s no longer syncing or even connecting as it used to, there are a few different options for you to try before contacting Fitbit.
What data is syncing between my Fitbit and my phone?
When your Fitbit syncs, it is actually syncing your health and fitness data from the device to your phone.
This information includes your heart rate, sleep metrics, steps made, exercise minutes, etc.
This Fitbit device data syncs with your Fitbit dashboard, so you can review that data on any other device or computer with the Fitbit app or log in to your Fitbit account via the website.
Most Fitbits sync to your phone, tablet, and some computers using Bluetooth Low Energy (BLE) technology.
However, the Fitbit Aria and Fitbit Aria 2 use WiFi to connect directly to your router.
Look at Fitbit’s current service status
Sometimes there are problems at Fitbit that span way beyond your individual device. So before you tear your hair out, check the current status and announcements at Fitbit via its server status page.
Look for any announcements at the top regarding outages, particularly under the Device Sync/Pairing and Authentication categories.
If you see there are reported problems at Fitbit, the only thing you can do is wait! The issues are beyond your control.
Check how many devices sync with your Fitbit
When I use the Fitbit app on both my iPhone and iPad and sync with my Fitbit Versa 3, I run into syncing problems.
Although Fitbit claims you can sync with multiple devices (like a phone and a tablet), it does not seem to work for my Versa and me.
Whenever my Fitbit syncs with my iPad, the next time I use the Fitbit app on my iPhone, it can’t find my Fitbit.
What worked for me was keeping the Fitbit app on my iPhone and deleting it from my iPad.
That way, my Versa 3 is only communicating with one device (my iPhone.)
For me, this solved the problem of constantly seeing messages that it could not find my Fitbit, connect to it, and sync.
So, if you have the Fitbit app installed on multiple mobile devices, try deleting it from all devices but one.
See if that solves your syncing issues as it did for me.
Now, if you want to keep the Fitbit app on both devices, either power off one of those devices or turn its Bluetooth off and then see if your Fitbit syncs.
Also, if you upgraded your phone to a new model and still have that old device, make sure you delete the device from the Fitbit app or remove the Fitbit app from that old device.
Close the Fitbit App
The first and most obvious answer to getting the Fitbit to sync again is restarting the Fitbit app.
This means you need to force close the app and re-open it.
Force close the Fitbit app on Apple iOS or iPadOS
- Open the app switcher by swiping up from the bottom to the middle of your screen or double-pressing the home button. Then choose the Fitbit app and swipe it up off the top of your screen.
Force close the Fitbit app on Android
- Go to Settings > Apps or Apps & Notifications > Tap the Fitbit app > Force Stop and confirm with OK.
Once the Fitbit app is opened again, make sure your Fitbit Versa or other model is on and in range.
You should then see a progress bar in the top left-hand corner, showing whether the Fitbit is syncing.
Remove and reinstall the Fitbit app
If closing the app and restarting it did not help, try to delete and reinstall the Fitbit app via the App Store or Google Play Store.
When you delete the app, you lose any data that has not yet synced your Fitbit account. However, all other data since the last sync remains in your account and will not automatically get deleted.
Check for updates for the Fitbit app
One issue I have seen over the years is when folks forget to update their applications properly.
Sometimes, you may install an app and think it will just work forever, but those “bug fix” releases are essential.
Whether you own an iOS or Android device, you can open up the App Store/Play Store.
Then, check to see if an update is available and download the update if applicable.
You also want to make sure that your smartphone itself is properly updated. On iOS, here are the steps:
- Open Settings. Select General.
- 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.
If an update is available for your smartphone, there may be some incompatibility issues. Ensuring that the app and your phone are updated is extremely important.
Reboot the Fitbit device
Another one of the easiest ways to get everything working again is to “reboot” your Fitbit.
This is done pretty quickly and is similar to the ole’ adage of “unplugging it, then plugging it back in.”
Restarting your Fitbit does not delete any of your data!
It’s a quick and easy way that will not impact, delete, or change your data in any way.
Here are the steps to correctly restart your Fitbit:
Press and hold the button or hold the side button or the back (left) and bottom buttons for 10 seconds until you see the Fitbit logo on the screen. This should typically take no more than 10 seconds. Do not release these buttons until the logo appears–even if it takes more than 10 seconds.
- Let go of the buttons.
From there, your Fitbit restarts and goes through rebooting itself. If you still have issues with your device, turn it off and turn it back on.
Have a different Fitbit model or tracker?

But you can also restart your Fitbit from the software on the smartwatch.
To restart your Fitbit via 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.
- Press to confirm to shut down your device.
- Wait 1 minute and turn your Fitbit or another model back on.
This method alone has been one of the biggest bits of help for folks with issues.
Toggle your phone’s Bluetooth off and on
If you continue to experience issues with syncing, you’ll likely want to try to toggle Bluetooth on and off.
This won’t unpair the Fitbit from your smartphone altogether but will help provide a “jolt” to try and get syncing to work again.
Unpair or Forget your Fitbit from Bluetooth, then re-pair it
In some rare cases, Fitbit also suggests removing the Fitbit from your paired Bluetooth devices. Here are the steps to do so on iOS:
- Open Settings or Settings > Connections.
- Select Bluetooth.
- Tap your Fitbit’s name.
- Scroll down and select “Unpair” or “Forget this device.”
Instead of pairing your Fitbit through the Bluetooth settings, open up the Fitbit app.
This guides you through the pairing steps while also ensuring that your Fitbit and smartphone communicate.
For a step-by-step guide see this article: How to pair your Fitbit to your iPhone, iPad, or Android device.
Check Always Connected and All-Day Sync (for older app versions)
If you run an older version of the Fitbit app on your Android or Apple device, you might need to turn on a few additional settings, Always Connected and All-Day Sync.
The most recent Fitbit app versions no longer include these options but check out these settings if you can’t update the app or don’t want to.
Fitbit has integrated a few new features within its app that help keep your devices connected. These come in “Always Connected” and “All-day Sync.”
By default, these are turned on but will make sure 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.
Tap the Fitbit icon in the app’s top right-hand corner to check whether this is enabled. This shows you the settings for your specific smartwatch/tracker.
You can scroll down and see the toggles for both Always Connected and All-day Sync. If these are not turned on, try turning them on and close the Fitbit app.
This could help solve your syncing issues and get your Fitbit back into working order.
Clear the Fitbit app’s cache (Android only)
Android phone users have a few more options for the Fitbit app versus iPhone and Apple users, including clearing the cache.
- On your Android device, open the Settings app.
- Choose Apps > Fitbit.
- Select Storage & cache.
- Tap Clear cache.
- When it successfully clears, the option to clear the cache grays out, and the cache zeros out.
- Restart your phone and try synching again.
If problems persist, there’s another option to Clear storage that removes all your user data from the Fitbit app, including settings and files.
Since Fitbit stores your data on its servers, you are only clearing data from your phone, not your account. So you don’t risk losing your Fitbit history.
Notice that your Fitbit’s battery is draining fast?
Fitbit designed your device to always connect to your phone/tablet via Bluetooth. That’s why you don’t miss any notifications.
So if your Fitbit’s battery drains faster than expected, try keeping it closer to your paired phone or tablet.
Your Fitbit uses more battery when it’s farther away from the device it syncs with!
These are some of the most popular methods to get syncing back to working on your Fitbit Sense, Versa Series, or any other Fitbit wearable. If you run into more issues, feel free to reach out in the comments below.
We love our Versa 3 and think that Versa is one of the best smartwatches on the market and is a great device to own. Hopefully, we see future iterations of the Versa Series released with new features and better specs.
In the meantime, sound off and let us know what you think about how Fitbit is doing in its fight in the fitness space.
