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, your fitness activity goes to the Fitbit app on your mobile, which then sends all of the new information to the Fitbit servers via Wi-Fi or your mobile network.

The Fitbit app can also send information back to the Fitbit device during a sync. If another source collects fitness activity for the same account, the info downloads to the tracker to reflect the correct amount of exercise performed on that day. Syncing can also update a Fitbit tracker's time during daylight savings time or traveling to a different time zone.

All Fitbit trackers can sync via Bluetooth to all modern iPhones and Android models.

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. Select the 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.

  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. Select 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 and Solutions

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 pairing with more than one device simultaneously. Doing so may seem like a good idea, but it can cause the Fitbit to refuse to sync with anything and will require a hard reset. An easy solution to this problem is to enable Bluetooth on only the device 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. Still, you can't sync your Fitbit devices with it due to the console hardware not having any Bluetooth functionality. You can use the Xbox One Fitbit app can be used to check your stats and leaderboards.
