Alternative Syncing To Phones Tablets And iPads

Fitbit continuously tracks our health data 24/7. When you enable “All-Day Sync,” the Fitbit syncs with the app multiple times throughout the day. So, the device you sync should be such that you interact it frequently throughout your day. Most of the time, you use your phones, tablets, or iPads, which are easily portable anywhere. But what if your phone crashed or needs maintenance? Will you miss the syncing feature? You will be happy to know you can even sync your Fitbit to your laptop or computer.

  1. Mac or any computer with at least Windows 8.1 operating system
  2. Fitbit Connect app on your computer
  3.  BLE support on your computer OR Fitbit Bluetooth Dongle

Troubleshooting Syncing Problems

Sometimes, the Fitbit appears with syncing problems. When Fitbit is connected to your mobile phone and app, it records your health statistics regularly. But when it isn’t synced, the stats may be stored in Fitness Tracker only. It is necessary to solve this issue. Here we suggest some ways to help you sync your Fitbit to your phone again:

Charge Your Fitbit And iPhone

One of the major reasons for Fitbit not syncing is not having an adequate battery on your phone or Fitbit. When you have less battery on your iPhone, it can direct the phone towards “Low Battery Mode.” Enabling such a mode also prevents Fitbit from syncing.

So, for proper and continuous syncing, charging both Fitbit and our phone is mandatory. Hence, make sure both of your devices are adequately charged for the whole day.

Update Your Fitbit App And Fitbit Device

The Fitbit Company updates and brings new changes in its application and devices periodically. Therefore, you need to update to the latest version of the app for proper syncing. Sometimes, when you use older versions of the app, there may be problems in syncing.

Make Sure Fitbit App Is Running In The Background

If you don’t know, let me tell you, the Fitbit and iPhone sync only when the Fitbit app is running in the background. The Fitbit app may not be running in the background due to the following two reasons:

  • When you “Hard Close” the app
  • The mobile operation has stopped due to low memory or battery

 Make sure you keep the app running in the background for proper and continuous syncing.

Fix Bluetooth Issues

Keep your Fitbit device and your iPhone in the Bluetooth connectivity range. They can be connected at a maximum range of up to 15 to 20 feet only.

Foremost, you need to make sure your phone and Fitbit are connected via Bluetooth.

Wait? Have you turned the Bluetooth on?

Update Your iPhones Operating System

To sync your Fitbit to your android phone, you will need the latest version of the Apple operating system. Upgrading to your latest operating system can help sync your phone with Fitbit.

Confirm that you fix all the above-mentioned problems. These are major issues, but if you are still having problems, these small procedures can assist you:

Sync To A Single Device At Once

You can connect to multiple devices with your Fitbit Fitness Tracker. But when multiple devices like phone and tablet or phone and laptop are in range, then it may be a reason for not syncing. To assure that multiple devices aren’t in range, and if they are, make sure the Bluetooth of only a single device is turned on.

Restart Your iPhone And Fitbit 

As we restart the computer when it misbehaves or stops working appropriately, it’s the same with your phone and Fitbit. You can restart any one or both of the devices to troubleshoot this problem.

Turn Bluetooth On And Off 

The simple process of turning Bluetooth off and then turning it on again can help to sync Fitbit to your phone. To turn off the Bluetooth, go to “Settings” and then to “Bluetooth” and switch the toggle on and off.

Verify that “Airplane Mode” or “Flight Mode” is turned on.

Uninstall And Then Again Install The Fitbit App

When your Fitbit app becomes stubborn and refuses to sync with the Fitbit Fitness Tracker or Smartwatches, then you must also be a little harsh and uninstall it. Once you remove the app from your device, you can again install it from the Apple Appstore.

Remove All The Connected Devices

We connect AirPods, speakers, Fitbits, and many other devices through Bluetooth. When there are many “connected” devices, the Fitbit can deny syncing with your iPhone. So, what you can do is remove all the devices from the “connected” list and connect your Fitbit again.


We all are aware of how important it is to sync your Fitbit with your phone. Don’t let syncing problems hinder you from enjoying a lot of amazing features. Use the above-mentioned solutions to fix your syncing issues.

 While you sync, a lot of data are transferred from your Fitbit to your phone and vice versa. You can transfer your health stats from Fitbit Tracker to the Fitbit app. And you can allow notifications and updates from your Fitbit app to your Fitbit. Therefore, fasten your syncing problems and enjoy your Fitbit features to the fullest.
