If your Fit bit not syncing properly with either your phone or app, you are neither alone nor an exception to the rule. Many Fitbit users face this niggling issue wherein the device suddenly stops communicating with the app or the Bluetooth, leaving you with the aggravation of either receiving old data or, somewhat worse, not being able to access any data! This guide will take you through every possible reason for the non-syncing of your Fitbit and allow you to rectify the situation without regard to whether it is a simple flaw in the app or a deeper issue of connectivity.
Why Your Fit Bit Is Not Syncing
First, one must understand the term sync or syncing. Syncing is the process wherein data stored on the Fitbit device, e.g. steps, heart rate, sleep, is shared with the Fitbit app on your phone or tablet. If syncing does not occur, the app will remain unupdated, and fitness stats will be unreliable.
Some users notice Fitbit is not syncing with the app, while other users complain about their Fitbit not syncing with phone or Fitbit not connected to Bluetooth. All these issues are often interrelated and caused by a few common factors.
Top Reasons Why Your Fitbit Won’t Sync
Let’s delve into some of the reasons behind the issue you experience with Fitbits when they do not sync:
- Interference in Bluetooth Connection
Bluetooth is the link for the Fitbit device to communicate with your smartphone. In case Fitbit is not connected to Bluetooth, it simply won’t sync. Any Bluetooth glitch, distance exceeding normal operational range, or perhaps too many connected devices may cause interference. - App Permissions & Background Activity
Some phones restrict background activity or app permissions. If the Fitbit app isn’t allowed to run in the background or use Bluetooth, syncing will fail. - Old Fitbit App and Device Firmware
If you haven’t updated the app, or rather your firmware for some time, you might face an incompatibility issue. This results in the odd situation where Fitbit not syncing with app even though Bluetooth shows as connected. - More than one device logged in
Having the same Fitbit account signed in on two or more devices causes a conflict in syncing. For instance, you may have the problem with my Fitbit won’t sync with my phone because the tablet or a second phone might be still connected to your account. - Phone compatibility
Some phones—especially budget-oriented or older Android models—may not fully support the Fitbit app’s syncing protocols. This could be why your Fitbit won’t sync no matter what you do. - Wi-Fi or mobile-data connectivity
Bluetooth is the old-school way to sync device-to-phone. The Fitbit app is supposed to work on Wi-Fi or mobile data to keep your online dashboard updated. Slow Internet can delay sync updates or create partial syncing.
Step-by-Step Troubleshooting Guide
Try doing everything in stepwise fashion if you have this dreaded fit bit not syncing issue; for the majority of the users, the issue is resolved without having to contact tech support.
✅ Step 1: Restart Your Fitbit Device
This will clear any internal cache and so resolve any minor software glitches. Make sure you follow the exact steps on how to restart your device, according to your particular model.
✅ Step 2: Reboot Your Smartphone
It would be better to reboot your phone so that Bluetooth settings and background services can have a reset. Most of the temporary bugs causing these fitbit won’t sync issues are fixed.
✅ Step 3: Turn Bluetooth Off and On
Go to the Bluetooth pane of your phone, turn off Bluetooth for a couple of seconds, and then turn it on again. Make sure only one Fitbit device is paired.
✅ Step 4: Forget Device and Re-Pair

✅ Step 9: Reinstall the Fitbit App
Uninstall and then reinstall your app from your phone. Log in using your Fitbit credentials, then proceed to re-pair your device.
Fitbit Model-Specific Syncing Issues
Unlike many other models, various syncing behaviors may be observed:
Fitbit Charge series (Charge 4,5): The syncing has been known to be often reliable but Bluetooth conflicts may still arise.
Fitbit Sense and Versa series: There are firmware specs of errors causing fitbit not syncing with phone errors until updates come out.
Fitbit Luxe and Inspire models: The lighter and simpler ones, but still reliant on the phone app for syncing accuracy.
In case your model is a newer one and you are still faced with syncing problems, there is an alternate set of causes why: app permissions or OS compatibility.
