Problem #1: Fitbit not syncing
Jimmy Westenberg / Android Authority
Fitbit trackers sync with Android devices via Bluetooth, and, unfortunately, that technology can be unreliable. If you have trouble syncing data from your Fitbit to your Android device, your solution may lie in your Fitbit app’s Settings menu.
- Make sure the Fitbit app is installed on your phone. You’ll also need to make sure your phone has Bluetooth turned on (Settings>Bluetooth>On) and that you’re only trying to connect your Fitbit to one Bluetooth-enabled phone or tablet.
- Try removing and re-adding your Fitbit device from your Fitbit account. Open the Fitbit app, select your account photo, select your tracker, then tap the trash icon in the top-right corner. Select unpair. You can then pair your Fitbit device with your Fitbit account.
- If your smartphone is running Android 6.0 Marshmallow or later (it probably is), you may need to manually grant the Fitbit app permission to scan for Bluetooth devices.
- To do so, head to your phone’s Settings menu, select Apps & notifications, select Permission manager, select Location, select Fitbit, then make sure the Allow all the time option is selected.
- In addition, your phone’s location services need to be turned on to scan for Bluetooth devices. To do so, head to your phone’s Settings menu, then select Location. Once you’re there, turn on the Location toggle at the top of your screen.
- You may need to force quit the Fitbit app. From your mobile device, head to Settings>Apps & notifications>See all apps>Fitbit>Force Stop.
- Alternatively, you can press and hold the Fitbit app icon on your home screen and release it when you feel a vibration. Tap the small i icon. Then tap Force stop.
- Try turning Bluetooth off and on again. From your mobile device, head to Settings>Bluetooth, then turn the Bluetooth toggle off then on. You can also turn off the Bluetooth toggle by tapping the icon in your quick settings panel.
- Try restarting your mobile device.
- If all else fails, try uninstalling and reinstalling the Fitbit app.
Problem #2: Fitbit not receiving notifications from Android device
Andy Walker / Android Authority
Sometimes Fitbit trackers won’t receive notifications from Android devices. If this is happening to you, you may need to restart your fitness tracker or change your phone’s Bluetooth settings.
- First, make sure you have notifications enabled in the Fitbit app. Open the app on your smartphone, tap your profile icon, then tap your device. Scroll down and select Notifications. From there, you can turn on/off call, text, and app notifications.
- Make sure you’re within 20 feet of your mobile device. As mentioned, Fitbit trackers connect to smartphones via Bluetooth, so you’ll need to make sure you’re in range to stay connected. If your tracker and mobile device are too far away from one another, you won’t receive notifications, or they may be delayed.
- Make sure you don’t have another Bluetooth device connected to your smartphone. This may cause interference that prevents notifications from appearing on your Fitbit tracker.
- Make sure Do Not Disturb mode is turned off on your Fitbit device.
- Fitbit Luxe: From your watch face, swipe down. Make sure the Do Not Disturb setting is turned off.
- Fitbit Sense and Versa 3: From your watch face, swipe from left to right. Make sure the Do Not Disturb icon is unchecked.
- Fitbit Inspire 2, Inspire, and Inspire HR: Navigate to your device settings, then scroll down to the Do Not Disturb option. Tap it, then ensure Do Not Disturb is turned off.
- Fitbit Charge 4 and Charge 3: Touch and hold the side button for a few seconds, and a Do Not Disturb option will appear. Make sure this setting is turned off.
- Fitbit Versa 2, Versa, Versa Lite, and Ionic: From your watch face, swipe down to access your notifications, then again from the top of the screen. You should see three icons show up near the top: music, wallet, and quick settings. Tap the grey quick settings icon on the right. Make sure the Do Not Disturb icon is unchecked.
- Fitbit Ace, Ace 2, and Ace 3: You can disable notifications from the Fitbit app on your smartphone. Open the app on your smartphone, tap your profile icon, then tap your device. Scroll down and select Notifications. From there, you can turn on/off notifications for your device.
- Fitbit Charge 2: Hold the side button while on the watch face. Do Not Disturb mode should toggle on/off.
- Fitbit Surge: Swipe over to Settings and make sure Notifications is set to On.
- Fitbit Blaze: Hold the top-right button for a few seconds and make sure Notifications is set to On.
- Make sure Do Not Disturb mode is turned off on your phone.
- You may need to force quit the Fitbit app. From your mobile device, head to Settings>Apps>See all apps>Fitbit>Force Stop.
- Try turning Bluetooth off and on again. From your mobile device, head to Settings>Bluetooth, then turn the Bluetooth toggle off then on. You can also turn off the Bluetooth toggle by tapping the icon in your quick settings panel.
- Try restarting your mobile device.
- If all else fails, try uninstalling and reinstalling the Fitbit app.
Problem #3: Fitbit not charging
Fitbit not charging? Nobody likes to wake up in the morning to a dead Fitbit. You may need to switch charging cables or clean your device.
- Make sure your Fitbit tracker and charging cable are clean. Dust and debris can accumulate over time, which could prevent the device from charging properly. Here’s a guide on how to clean your tracker.
- Try plugging your Fitbit charger into a different USB port. Using a UL-certified wall charger will work, as will a simple USB input on a computer. Your Fitbit may not charge properly if you’re using a USB hub.
- Make sure your Fitbit device’s pins are properly lined up on the charging cable. If the charging pins on your Fitbit device aren’t perfectly lined up on your charger, your device won’t charge properly. We’ve found this to be particularly common when charging the Alta and Fitbit Charge devices.
- You might need to restart your Fitbit device. For instructions on how to do so, a walkthrough can be found below.
- If you notice your Fitbit’s charger is a little beat up, you might need to replace it. You can buy a new charger at Fitbit’s website or on Amazon.
Problem #4: Problems with Quick View and tap recognition
Many Fitbit devices come with a Quick View feature, which allows you to simply raise your wrist to wake the display. Some of these devices — like the Alta, Charge 2, and Charge HR — also come with tap-enabled displays, meaning you can’t swipe through menus like you would on a normal touchscreen device. Instead, all it takes is a simple tap near or on the display to swipe through your daily stats.
Unfortunately, many Fitbit users claim to have problems with Quick View and tap recognition being too slow to respond. If you’re in this boat, the answer may lie in your Fitbit app’s Settings menu.
Potential solutions for Quick View problems:
- For Quick View to work properly, your Fitbit device needs to know which wrist it’s being worn on and whether you’re right-handed or left-handed. To check if this is the problem, open the Fitbit app, select your profile photo, select your tracker, then make sure the Quick View toggle is turned on.
- On that same screen, you’ll see options to change your wrist placement. Make sure you’re wearing your Fitbit on the correct wrist and that you’ve chosen whether or not you’re right or left-handed. This will have a big effect on whether or not Quick View works properly.
Potential solutions for tap recognition problems:
- Make sure you’re tapping your Fitbit device in the right spot. Fitbit recommends aiming toward the bottom of the display, where the tracker meets the band. Also, make sure you’re not tapping too forcefully or too softly.
- If there’s a second-or-two delay from the time you tap your device, that’s normal. Just make sure you’re giving your device time to react. If you’re having trouble with tap recognition, try slowing down your taps.
Problem #5: Fitbit isn’t updating properly
Some people have problems updating their Fitbit device’s firmware. If this happens to you, you may need to restart your tracker or try syncing with another mobile device or computer.
- Try restarting your Fitbit device. For instructions on how to do so, a walkthrough can be found below.
- After that, try updating your device again. If it’s still not working, try restarting your mobile device.
- If you’re trying to sync your Fitbit with your mobile device, try removing the Bluetooth connection from your mobile device.
- To do this, navigate to Bluetooth in your mobile device’s settings menu, find your Fitbit device, then choose Forget.
- You might need to try updating your Fitbit via another mobile device or computer. To do so on a computer, head to this link, log into your Fitbit account and try updating your firmware.
- If you still can’t update, try removing your Fitbit device from your Fitbit account.
- If you’re using a mobile device, head to Settings>[Fitbit device]>Remove this device.
- If you’re using Fitbit’s website, log into your account, click the gear icon on the top-right of your screen, then click Settings>Devices>[Fitbit device]>Remove this device from your account.
- Next, you’ll need to add your tracker back to your Fitbit account. Under the Account section of the Fitbit app, choose Set Up a Device and follow the instructions. Once your device has been re-connected, tap Update.
Problem #6: Fitbit’s silent alarm stopped working
Most Fitbit devices have the ability to wake you up in the morning via silent alarms. If your silent alarms aren’t working, there aren’t a ton of options. You’ll need to check your Fitbit’s vibration motor using the steps below. If that doesn’t work, Fitbit recommends you contact customer support.
- First, make sure you have a silent alarm set on your Fitbit device. To do this, open the Fitbit app, choose your account photo, select your Fitbit device, then choose Silent Alarm.
If that wasn’t the problem, here’s how to test your Fitbit’s vibration motor:
- Fitbit Luxe and Charge 5: Simply plug the Luxe into its charging cable. You should feel a vibration.
- Fitbit Sense: Swipe over on the screen and select Timer on the Sense. Tap Stopwatch and then tap the Play icon. The watch should vibrate. Connecting the device to the charging cable and plugging it in should make the watch vibrate too.
- Fitbit Versa 3: The steps are similar on the Versa 3. Swipe over and select Timer, tap Stopwatch, and then tap the Play icon. Plugging in the tracker to charge should work as well.
- Fitbit Inspire 2, Inspire, and Inspire HR: Plug the Inspire into its charging cable. You should feel a vibration.
- Fitbit Charge 4: Simply press the side button on your Charge 4 while it’s turned on. Your tracker should vibrate.
- Fitbit Versa 2: On your Versa 2, swipe over and select the Timer option. Tap Stopwatch, then tap the Play icon. Your tracker should vibrate.
- Fitbit Versa Lite: On your Versa Lite, swipe over and select the Timer option. Tap Stopwatch, then tap the Play icon. Your tracker should vibrate.
- Fitbit Charge 3: Simply press the side button on your Charge 3 while it’s turned on. Your tracker should vibrate.
- Fitbit Versa: On your Versa, swipe over and select the Timer option. Tap Stopwatch, then tap the Play icon. Your tracker should vibrate.

- Alternatively, you can swipe over to the Timer screen, tap it, then tap the play icon. Your tracker should vibrate.
- Fitbit Ace 2 and Ace 3: Plug your Ace 2 or Ace 3 into its charging cable. You should feel a vibration.
- Fitbit Ace: Clip your Ace to the charging cable, and make sure the cable is plugged into a USB port on your computer. Press the button on the charging cable to check vibration.
- Fitbit Blaze: Swipe over to the Timer screen, then tap it. Tap Stopwatch, then tap the play icon. Your tracker should vibrate.
- Fitbit Alta: Clip your Alta to the charging cable, and make sure the cable is plugged into a USB port on your computer. Press the button on the charging cable to check vibration.
- Fitbit Alta HR: Clip your Alta HR to the charging cable, and make sure the cable is plugged into a USB port on your computer. Press the button on the charging cable to check vibration.

- Fitbit Surge: Plug your Surge into the charging cable, and make sure the cable is plugged into a USB port on your computer. Your tracker should vibrate.
- Fitbit One: Clip your One into the charging cable, and make sure the cable is plugged into a USB port on your computer. Your tracker should vibrate.
Problem #7: Fitbit band breaks
Fitbit devices are pretty high-quality pieces of technology, but they’re definitely not invincible. If your Fitbit’s band is starting to break, you’ll need to take advantage of the company’s warranty policy.
It’s worth noting that if you own a recent Fitbit device and are out of warranty, you can simply buy a new band without replacing the whole unit. If you have an older tracker like the Charge HR, Surge, or Flex, you’ll want to follow the steps below to get it replaced.
- As noted on Fitbit’s Returns and Warranty page, you have the option to return your Fitbit device for a full refund within 45 days of your purchase date, provided you ordered the device from Fitbit.com.
- In addition, products ordered in November and December may be returned through January 31 of the following year, or 45 days (whichever is longer).
- Fitbit also offers a one-year limited warranty to the original purchaser of the product, guaranteeing that the Fitbit product is free from defects in materials and workmanship under normal use. This means Fitbit will fix the damages done to your Fitbit device within the first year, provided you’re the original purchaser of the device. If you’re not, unfortunately, you may be out of luck.
- For more details on the company’s policies, be sure to visit Fitbit’s Returns page or contact the company’s customer support team to file a claim.
Looking for replacement bands for your device? You can, of course, head to Fitbit’s website to buy a replacement or head to the Amazon links below for a cheaper alternative:
Problem #8: Fitbit Sense ECG reading issues
Jimmy Westenberg / Android Authority
Are you having Fitbit Sense ECG problems? You’re not alone. A small number of users seem to be experiencing bugs affecting the Fitbit Sense’s electrocardiogram (ECG) recordings.
Users on the Fitbit forums said Fitbit has contacted them and suggested they return their Fitbit Sense smartwatches to the company. Fitbit told these users that it would replace their smartwatches free of charge. The problem at hand is an unspecified “hardware issue.” Fitbit UK confirmed (via The Verge) that the ECG app on some Fitbit Sense models incorrectly displays results as “inconclusive.”

How to Fix Your Fitbit Not Syncing
If you own a Fitbit, you may occasionally run into an issue where it won't sync to an iPhone, Android device, or computer, and the app tells you the sync process is unable to complete or that the fitness tracker can't be found. There may be several causes for this malfunction. There are also just as many fixes that can be implemented quickly and without any risk to the device. We outline these fixes below.
The tips in this article can be used to fix sync problems with all Fitbit tracker models from Fitbit Charge 3 and Fitbit Ace 3 to Fitbit Ionic and Fitbit Versa.
Cause of Fitbit Sync Errors
Fitbit sync errors are usually related to the fitness tracker becoming disassociated with the smartphone, tablet, computer, or iPod touch it was initially connected to. This can be caused by connecting to too many devices at once, the Bluetooth not working properly, or a minor glitch in the Fitbit's operating system.
How to Fix a Fitbit Tracker Sync Problem
It's difficult to pinpoint exactly why a Fitbit won't sync properly to an iPhone, Android, or another device. However, there are a variety of proven solutions that can fix the problem, and these work with all Fitbit fitness tracker models.
Force a manual sync. Sometimes the Fitbit app needs a little prodding to initiate sync even after it's opened. To force a sync, tap the member card icon, tap the name of the Fitbit tracker, and then tap Sync Now.
Check the Bluetooth settings. A Fitbit tracker syncs data to smartphones, tablets, and computers using Bluetooth, so it won't be able to connect if Bluetooth is disabled on the device.
Bluetooth can be turned on and off from quick menus on most smart devices. On iPadOS, swipe down in the upper-right corner to open this menu. On Android and Windows Phone, swipe down to open it.
Install the Fitbit app on your device. If you purchased a new Fitbit tracker, you likely installed the official app on your smartphone, tablet, or computer to set it up. However, if you received a Fitbit second-hand, you may not have. Unlike other devices, a Fitbit requires installing a special app to connect to another device and sync data.
Update the Fitbit. The device may have trouble connecting to the tracker if it's outdated.
Only sync the Fitbit to one device. It may seem like a good idea to pair your Fitbit tracker with your iPhone while out of the house and your Windows 10 computer for when you're at home, but this can cause a conflict for the tracker when it tries to connect to both at the same time. The best way to fix this is to turn off Bluetooth on one device when trying to sync to the other. You can also turn the second device off completely.
Disable Wi-Fi. Sometimes having a smartphone or tablet's Wi-Fi and Bluetooth turned on at the same time can prevent each of these technologies from working properly. If you're trying to sync a Fitbit tracker, this can hinder the Bluetooth connectivity and prevent it from syncing.
Check the Fitbit battery. While Fitbit trackers have a long battery life, these devices need recharging every day or so. If a tracker isn't syncing, it may have run out of power and turned off. This is likely if you own a Fitbit One or Fitbit Zip. These are usually placed in a pocket or bag and are easy to forget about when it comes to device charging time at the end of the day.
Restart the Fitbit tracker. Restarting a Fitbit is essentially the same as restarting a computer. It refreshes the device's operating system and typically fixes any issues you may experience, such as syncing problems.
Instructions for restarting a Fitbit vary from model-to-model but generally involve plugging the tracker into the USB charging cable, connecting it to a power source, and holding the main button for around 10 seconds. If done correctly, the Fitbit logo flashes on the screen, and the device restarts. Restarting a Fitbit won't delete any data besides notifications.
A restart is usually required after encountering one of the problems mentioned above, such as Wi-Fi and Bluetooth conflicts or being connected to multiple devices.
Reset the Fitbit tracker. Resetting is a last resort, as it deletes all data and returns the Fitbit to its factory settings. You can restore any data synced to your online Fitbit account after the reset. Resetting a Fitbit differs depending on which model you own, with some requiring a paperclip inserted into a hole while others are done in the device's settings. Some trackers, such as the Fitbit Surge and Fitbit Blaze, have no factory reset option.
Don't confuse restarting and resetting when talking to online or offline customer support. Restarting a Fitbit turns it off and on again while resettingdeletes everything on it.
Thanks for letting us know!
Having trouble syncing your Fitbit Sense or Versa Series watch or another model Fitbit with your mobile phone, tablet, or computer?
If so, you aren’t alone, as multiple users have reported syncing issues after a recent update.
As Fitbit owners, we share your frustration as it happened to us too! That’s why we wrote this article, to offer help and hopefully get your Fitbit, whatever its model, syncing again!
Follow this quick checklist to help fix syncing issues with your Fitbit
- 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
- Shutdown 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
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 like 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, exercised minutes, and so forth.
This Fitbit device data syncs with your Fitbit dashboard, so you can review that data on any other device or computer that has the Fitbit app or logging into 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.
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 that you can sync with multiple devices (like a phone and a tablet), it just does not seem to work for my Versa and me.
Every time 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 the messages that it could not find my Fitbit, connect to it, and sync.
So, if you have the Fitbit app installed on more than one mobile device, try deleting it from all devices but one.
See if that solves your syncing issues as it did for me.
Close the Fitbit App
The first and most obvious answer to getting the Fitbit to sync again is restarting the Fitbit app.
This means that you actually need to force close the app and then re-open it.
Force close app on Apple iOS or iPadOS
- Open the app switcher by swiping up from the screen’s 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 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 you whether the Fitbit is syncing.
Reinstall the app
If closing the app and restarting it did not help, try instead 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
One issue that 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 important.
Regardless of 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, then 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 easily 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 properly 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 normally 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 the process of 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?
Check out this article to learn your exact model’s steps: Need to restart or reset your Fitbit device? Learn the steps
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 clockface
- 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 who are having issues.
Toggle 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”
From there, 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 your smartphone are communicating.
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 if you can’t update the app or don’t want to, check out these settings.
Fitbit has integrated a few new features within its app that help keep your devices connected. These come in the form of “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 the data from your Versa or other Fitbit model to sync.
To check whether this is enabled, tap the Fitbit icon in the app’s top right-hand corner. This shows you the settings for your specific smartwatch/tracker.
From there, 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 then close the Fitbit app.
This could help solve your syncing issues and get your Fitbit back into working order.
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 normal, 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!
Lastly, Did you know that there’s an easy way to see your weekly activity reports using the FitBit app.
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 end up running into more issues, feel free to reach out in the comments below.
We love our Versa 3 and think that Fit 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.
Do you think the company is doing well in keeping up with Apple? Or would you like to see something even more innovative in its next smartwatch?
Why won't my Fitbit device sync?
- You have the Fitbit app open and on the Today tab on your nearby phone or tablet while you complete a weigh-in.
- The latest version of the Fitbit app is installed on your phone or tablet.
- The Bluetooth setting on your phone or tablet is on. To check, tap SettingsBluetooth.
- Your phone or tablet isn't managing other Bluetooth connections. If you have multiple Bluetooth products like speakers or headsets paired to your phone along with your Fitbit scale, you may have trouble using more than one at the same time. Turn off other Bluetooth connections when not in use.
- If you use more than one device to sync, make sure the other device isn't nearby. If the device is nearby, turn off Bluetooth on it.
- Your Fitbit scale's battery isn't critically low.
- Force quit and then reopen the Fitbit app.
- Go to SettingsBluetooth and turn Bluetooth off and back on.
- Turn your phone or tablet off and back on.
- Uninstall and reinstall the Fitbit app.
- If your Fitbit scale won't sync after you reinstall the app, log in to your Fitbit account on a different phone or tablet and try to sync.
- If your Fitbit scale still doesn’t sync, remove all other Fitbit devices from your account and from the list of connected Bluetooth devices on your phone and try to sync.
Aria & Aria 2
After weighing in on Fitbit Aria or Fitbit Aria 2, the scale should display a progress bar, followed by a check mark, which indicates the new measurement synced successfully.
If the scale doesn't sync, you may see one of the following error messages on the scale’s screen:
- NO SYNC
- WIFI Symbol with an “X”
- WRONG PASSWORD
- CONNECTION ERROR
- CAN'T CONNECT
- NO WIFI
- WEAK SIGNAL
- No error message, but the measurement doesn't sync to your Fitbit account
If any of these conditions occur, try weighing yourself again. If the scale successfully syncs, it may have been a temporary issue that doesn't require further troubleshooting. If the problem persists, try the following tips:
- Check that your router is on and working. If other devices are also unable to connect to your Wi-Fi network, restart your router.
- Remove the batteries from your scale for 10 seconds, then reinsert them to restart your scale.
- If you've made any changes to your network, such as a new router, network name, or password, see How do I reconnect my Fitbit scale to my wireless network?
- Your scale may be too far away from your router. Several walls, floors, or objects between the scale and router can cause interference. Try moving the scale closer to your router.
- The network may have too much traffic or there are too many other Wi-Fi networks nearby. Don't use public Wi-Fi to sync your scale.
If you still can't sync, contact Customer Support. For additional information on error messages, see Why isn't my Fitbit scale working?

Fixed: If your Fitbit won't sync here's how to solve it
If your Fitbit won't sync, you've come to the right place. Whether you have a Versa 3, Charge 4, Inspire or another Fitbit tracker or smartwatch, we're experts in troubleshooting syncing issues.
In this guide, we'll be explaining exactly how to sync a Fitbit with your iPhone, Android smartphone or computer – and what to do if it's having trouble syncing.
Most users are likely to come across syncing issues over time, and knowing how to transfer the data stored on your device to the Fitbit app is an essential skill.
Read on below to discover everything you need to know.
How to sync your Fitbit
Syncing 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 to the Fitbit app on your smartphone.
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.
Manually sync your Fitbit
To force your Fitbit to sync, 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 the Fitbit app
While this was a feature that previously appeared in Fitbit's app, the All-Day sync option has now been removed. So, as long as your phone is near your Fitbit device and they're paired with Bluetooth, they should sync regularly throughout the day to make sure your data is nice and up to date.
How to sync Fitbit with a computer
You don't need a smartphone to sync Fitbit data, and can actually use your computer by following these steps.
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 https://www.fitbit.com/login.

Fitbit has a great range of activity tracking devices. For the average person who does the occasional run here and there, their wearables tick most of the boxes. But let’s face it, as much as we like our fitness trackers and smartwatches they are not perfect. Sometimes things will go wrong. Here’s what to do if your Versa, Sense, Charge, Inspire or other Fitbit is not syncing to your iOS device, Android device, tablet, Mac or PC.

Why do I need to sync my Fitbit?
Most wearables these days have displays. This is useful for viewing the current day’s stats. But for longer term trends, insights and other info – you do need to head over to the accompanying smartphone app. Because this is where your long-term data sits. A smartphone’s large display is much more conducive for viewing this sort of information Also, there’s only so much memory on a Fitbit tracker. So you do need to transfer fitness data from time to time to something with a large memory.
Syncing does this for you. The wearable uses a Bluetooth Low Energy (BLE) connection to connect to a device – most often a iPhone or Android device. Some Fitbit devices, such as its Aria range of scales, use WiFi to connect and sync.
Why is my Fitbit not syncing?
All electronics and software are susceptible to problems. And the Fitbit on your wrist is no exception. One of the issues that can occasionally crop up is that your Fitbit Versa, Sense, Charge, Luxe or Inspire refuses to connect and sync information.
The software on your smartphone might not be able to find your fitness tracker or it might not be able to hold a connection. You might be getting the message in the smartphone app that sync process is unable to finish. Don’t worry – you’re not alone. These things happen sometimes.
There could be various reasons why your Fitbit is not syncing. So the fix will not be the same for everyone or every time. It could be because of a Bluetooth issue. Perhaps your Fitbit become disassociated from your phone. Maybe the Bluetooth is not switched on, or perhaps there are too many devices using the connection. It could even be a software glitch.
You can check when your Fitbit has last synced in the smartphone app. The information is shown if you click on the Today tab, your profile picture and then your device image. This can also be done via the website dashboard. Simply click on the gear icon and you’ll see the date/time of the last sync under the name of your Fitbit tracker.
How to fix Fitbit sync issues
We’ve pulled together a few troubleshooting steps that address common sync issues. Hopefully, one of these will do the trick. Most likely, this is a connection problem.
There is no danger to trying any of these steps. You data will remain intact both in the smartphone app and the tracker (the only exception is a factory reset). All of these solutions are worth a go if you’re experiencing the problem.
Fitbit not syncing – troubleshooting steps
- Do a manual sync
The Fitbit tracker should automatically sync every time you open up the smartphone app. You’ll be able to see that this is happening in the app.
If you’ve allowed in the settings of your Fitbit account, there will also be an auto sync performed every 15 minutes – as long as the Fitbit tracker is in close vicinity to your phone or other device. You do need to enable the Sync All Day option for that. Which can reduce the battery life of your Fitbit.
For smart scales that use the wireless network, the sync is done automatically whenever you weigh yourself. You’ll notice a checkmark on the scale display indicating the sync was successful.
Another way to sync is manually. Fire up the smartphone app and tap on the Sync Now option. You can do this whenever and how often you want. It is the easiest way of testing whether, indeed, there is a sync problem.
- Try restarting
A common resolution for any problem is the simple old restart. If the Fitbit is not syncing restart both your tracker and/or your smartphone. This is also the solution if your Fitbit is not responding to button presses, taps, or swipes or if it’s not tracking your steps and other stats.
A restart of your fitness tracker restarts the device, but does not delete any data. It is easily done. For example – on the Charge 3, press and hold the button on the left of its screen for 8 seconds. When you see a smiley icon and the tracker vibrates, your tracker has restarted. You are now ready to use it again. To restart your Versa, press and hold the back (left) and bottom buttons until you see the Fitbit logo on the screen. This should take less than 10 seconds. Let go of the buttons. See How do I restart my Fitbit.
If restarting doesn’t help, there are a few other things you can do. Read on.
- Software update
Make sure the latest version of the Fitbit app is installed on your phone. Also check to see if the software running on your Fitbit tracker is up to date. This can be done by tapping on Settings > General > Software Update in the accompanying smartphone app.
- Make sure your device’s battery isn’t critically low.
If a tracker isn’t syncing, it may have run out of battery juice. So it might be off or the Fitbit doesn’t have enough battery to perform the sync. Top it up.
- Check the Bluetooth connections
Perhaps it’s a connection issue. Is Bluetooth switched on on your phone? If not you’ll need to switch it on in order for the sync to work. The Bluetooth settings can be found in the settings section on your phone.
If it is switched on you can try force quitting the Fitbit app. Then toggle Bluetooth on your phone off and back on. Open up the Fitbit app to see if this has resolved.
You can also use the Bluetooth settings on your smartphone to see if your Fitbit is connected. Make sure there are no other Bluetooth devices around that might interfere with this connection. Switch them off if needed.
The same applies to Wi-Fi conflicts for Fitbit Aria scales. You can try all of this but instead of Bluetooth, do them with Wi-Fi.
- It is best to sync the Fitbit to only one device
Our recommendation is that you sync the fitness tracker or smartwatch to only one device. Theoretically you should be able to sync with multiple devices connected to the same account but it might lead to confusion. Having both devices around might cause a conflict if the Fitbit tracker tries to connect with both of them at the same time.
If you’ve used your fitness tracker with an app on another phone, make sure the Fitbit is not connected to that phone instead of the one you are currently using. The easiest way to do this is to switch off Bluetooth on the device you do not want to use to sync.
- Try a different phone, tablet or computer
If it still doesn’t work, log in to your Fitbit account on a different phone, tablet, or computer and try to sync. This will tell you if it is a problem with the Fitbit tracker or the device it is connecting to.
- Remove all devices from your account
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. You will be required to re-pair your Fitbit to your phone. This is easily done via the smartphone app. You’ll see a message asking you to allow your Fitbit device to pair with your device.
- Server outage
This does happen from time to time. The good news is there is nothing for you to do but wait for things to get up and running – the fault is entirely at Fitbit’s end. The bad news is that while you’re waiting you probably won’t be able to open the app, sync your device or even log onto Fitbit’s website. The best place to check if there is a server outage or other technical problem is downdetector.com.
- Factory reset your Fitbit
As a last resort, you can do a hard-reboot of your Fitbit. The bad news about this is that it will delete all the data on your tracker. Meaning you will lose anything that has not been already synced. So it is not the same as a simple restart. But the data that is on your Fitbit account will stay there.
A hard-reboot will restore the Fitbit to the condition when you bought it. Which means you will need to re-pair the device to the smartphone app and set it up as a new fitness tracker or smartwatch. See How to I factory reset my Fitbit.
