How do Fitbit devices sync their data?
Syncing is the process that transfers the data your device collects to your Fitbit dashboard. The dashboard is where you can track your progress, see how you slept, set goals, log food and water, challenge friends, and much more. Fitbit trackers, watches, and Fitbit Aria Air use Bluetooth Low Energy (BLE) technology to sync with phones, tablets, and certain computers. Fitbit Aria and Fitbit Aria 2 use Wi-Fi to connect directly to your router. The instructions in How do I set up my Fitbit device? explain how to make sure your device can sync to your Fitbit dashboard.
Data automatically syncs to the Fitbit app throughout the day. Each time you open the Fitbit app, your device syncs automatically when it's nearby. You can also use the Sync Now option in the app at any time.

- With your device nearby, open the Fitbit app to the Today tab .
- Press and hold on the screen and pull down (on Windows 10 devices, find the picture of your device at the bottom and pull up).

Choose your device to see syncing instructions.
After your Fitbit Aria or Fitbit Aria 2 is set up on your wireless network, it automatically syncs your stats to the Fitbit app after every weigh-in.
After you see your measurements, you should see a checkmark, indicating that syncing is complete. You can then view your data on in the Fitbit app.
Find information about your Fitbit device, such as firmware version, battery level, and when your device last synced:
Tap the Today tab > your profile picture > your device image.
On the fitbit.com dashboard, click the gear icon . The last time you synced is listed below the name of your Fitbit device.
If your device stopped syncing, the likely problem is a connection issue. For detailed information on how to diagnose and solve the problem, see Why won't my Fitbit device sync?
We recommend that you sync your tracker or watch daily. Most Fitbit devices record detailed minute-by-minute data for 7 days. (Fitbit Alta records minute-by-minute data for five days). Fitbit devices can store daily totals for up to 30 days.
If you have a Fitbit Surge, your device can store 35 hours of GPS data before deleting some data to make room for more.
You can sync your device with any compatible phone, tablet, or computer that meets syncing requirements. If you receive notifications from your phone on your Fitbit device, you'll need to disable the Bluetooth bond between your phone and Fitbit device before using a different phone.

If you have multiple devices, they can all sync to the same account to make sure you see a complete view of your activity. For more information, see Can I use more than one Fitbit device with the same account?
To improve your experience with notifications, syncing, and firmware updates, we removed the option to turn off all-day sync from the Fitbit app. When your phone is near your Fitbit device with Bluetooth turned on, it periodically syncs with the Fitbit app to update your stats and download available firmware updates. More frequent syncing rarely, if ever, noticeably decreases your device’s battery life. To learn more about what factors affect battery life, see Can I extend my Fitbit device's battery life?
