Syncing your Fitbit device to your iPhone or Android smartphone is the fastest and easiest way to send your latest fitness activity to your Fitbit account.

What Happens During a Fitbit Mobile Sync?

When syncing your Fitbit device to your smartphone, the Fitbit hardware wirelessly connects to your phone via Bluetooth. During this process, all of your fitness activity is sent to the Fitbit app on your mobile which then sends all of the new information to the Fitbit servers via Wi-Fi or your cellular network.

The Fitbit app can also send information back to the Fitbit device during a sync. If fitness activity has been collected via another source for the same account, this information will be downloaded to the tracker to reflect the correct amount of activity performed on that day. A sync can also update the time on a Fitbit tracker during daylight savings time or when traveling to a different time zone.

What Smartphones Work With Fitbit Trackers?

All Fitbit trackers can sync via Bluetooth to all modern iPhones and Android models. Only Windows phones running Windows 10 Mobile are able to sync to a Fitbit due to the official Fitbit app being unavailable on older Windows phone operating systems.

What You Need to Sync Your Fitbit

To sync your Fitbit tracker to your smartphone, you will need the following.

  • The free Fitbit smartphone app. If you're using an Android smartphone or tablet, you can download the app for free from the Google Play Store. Those using an iOS device such as an iPhone, iPad, and iPod will need the Fitbit app from the iTunes Store. Windows phone users will need the Fitbit app from the Microsoft Store.
  • A cellular or Wi-Fi internet connection so the Fitbit app can send the data to the Fitbit servers.
  • A smartphone with Bluetooth capability. All modern smartphones support Bluetooth so it's almost a guarantee that yours will have it. Bluetooth is wireless technology used to wirelessly connect your Fitbit tracker to your smartphone.

How to Sync a Fitbit to Your Smartphone

After the initial setup, your Fitbit tracker should routinely sync to your smartphone in the background. It's usually not required to manually sync your data. If you do want to manually sync your Fitbit with your smartphone though, perhaps to meet a Fitbit Challenge deadline so you can add your activity before the Challenge ends, here's what you need to do.

  1. Make sure that your Fitbit tracker is turned on.
  2. Make sure your phone's Bluetooth is enabled.
  3. Open the official Fitbit app on your phone.
  4. You should see a small icon of your Fitbit model on the main screen of the app. Depending on your smartphone type, it should be in an upper or lower corner of the screen. Tap on it.
  5. A small menu should pop up with the time your Fitbit last synced with the app and an icon that looks like two arrows forming a circle. Click on the two arrows to perform a manual sync.
  6. Your Fitbit will begin to sync with the app and a progress bar will appear. The entire sync should take no more than a few seconds.

Fitbit Syncing Tips & Solutions

  • Turn on Bluetooth. Bluetooth is essential for a Fitbit device to sync with a phone or PC. If you have a habit of putting your device in Airplane or Flight mode (which disables Bluetooth), make sure to turn it off before trying to sync your fitness data.
  • Only sync to one device at a time. One of the common causes of sync errors is a Fitbit device being paired with more than one device at the same time. Doing so may seem like a good idea but it can cause the Fitbit to get confused and eventually it will refuse to sync with anything and will require a hard reset. An easy solution to this problem is to only keep Bluetooth turned on for one smartphone or PC, the one you want your Fitbit to sync with.
  • Xbox One consoles can't sync Fitbits. The official Fitbit app may be available on Microsoft's Xbox One video game consoles but you won't be able to sync your Fitbit devices with it due to the console hardware not having any Bluetooth functionality. The Xbox One Fitbit app can be used to check your stats and leaderboards though.
