Syncing is the process that transfers the data your tracker 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. Your tracker uses Bluetooth Low Energy (BLE) technology to sync with mobile devices and certain computers. The instructions in How do I set up my tracker? explain how to make sure your Fitbit tracker can sync with the mobile device or computer you prefer.
Will syncing work on my device?
Fitbit apps are available for iOS and Android devices. We also offer a Windows 10 app that can be installed in any Windows 10 environment—phone, tablet or computer. For more information choose a section below.
Fitbit app for iOS
The Fitbit app for iOS is compatible with most iPhones, iPads, and iPods. To make sure your version is supported, check https://www.fitbit.com/devices. To learn more about using your tracker with an iOS device, watch the following video. (English only.)
Fitbit app for Android
Android devices must have both a BLE radio and software support. Because BLE is an optional component of Bluetooth 4.0, not all devices with Bluetooth 4.0 have it. A device can have the radio but not the software, or have software bugs that hamper BLE. If you're buying an Android device to use with the Fitbit app, make sure it appears on our supported devices list at http://www.fitbit.com/devices and review known issues at Which Android devices have known issues with the Fitbit app?

How often does my tracker sync?
If your tracker is paired to the Fitbit app on a mobile device, it syncs every time you open the app. It can also sync periodically throughout the day if you have All-Day sync turned on. If your tracker is paired to a computer, it syncs automatically every 15 to 30 minutes assuming the tracker and computer are in proximity.
You can also initiate a sync whenever you like if your tracker is nearby. Choose a section to see syncing instructions.
On the Fitbit app for iOS dashboard, tap the Account tab.
Tap the top of the screen where you see your tracker's name.
Find and tap Sync Now.
On the Fitbit app dashboard, tap the Account tab.
Tap your tracker name.
Find and tap Sync Now.
Windows 8.1 devices
On the Fitbit app dashboard, tap the menu icon (three dots) in the bottom right corner. Tap the sync option.
Windows 10 mobile devices and computers
On the Fitbit app for Windows 10 dashboard, tap or click the Account tab. Tap or click your tracker to see the sync option.
Mac or Windows 8.1 computers
Click the icon with a Fitbit logo located near the date and time on your computer.
Click Open Main Menu, and then click Sync Now. You may be asked to sign in, after which your tracker should sync with your account.
Where can I see when my tracker last synced?
If you're using a Fitbit app, tap the tracker image on your dashboard. On the next screen, tap your tracker name to see your last sync time, firmware version, and battery level at the top.
If you're using the fitbit.com dashboard, click the gear icon in the top right corner. You'll see the last sync time right below the tracker image.
Why can't I sync my tracker?
If your tracker stopped syncing, a Bluetooth connection issue is usually the culprit. For detailed information on how to diagnose and solve the problem, see Why won't my tracker sync?
How often do I need to sync?
A daily sync is recommended but not required. Most Fitbit trackers record detailed minute-by-minute data for seven days, so if you're able to sync weekly you'll find all your data on your Fitbit dashboard. (Fitbit Alta records minute-by-minute data for only five days). After seven days, Fitbit trackers can store daily totals for up to 30 days.
If you have a Fitbit Surge, your tracker can store 35 hours of GPS data before deleting some to make room for more. To ensure that all your GPS data is saved to your exercise history, sync your Surge regularly.
Can I sync my tracker with more than one device or a computer?
You can sync your tracker with any compatible mobile device or computer that meets syncing requirements. If you receive notifications from your mobile device on your tracker, you'll need to disable the Bluetooth bond between device and tracker before using a different device. For instructions see Why is my tracker only syncing with one mobile device?
Can I sync more than one Fitbit tracker to the same account?
