Once you've set up and started using your new tracker, you'll need to regularly transfer (sync) your tracker's data to Fitbit so you can see your activity history, earn badges, analyze your sleep logs, and more. You can sync your tracker using the Fitbit app on your compatible mobile device or Windows 10 PC, or by using a computer with Fitbit Connect installed.
Fitbit apps are available for iOS, Android, and Windows mobile devices as well as Windows 10 PCs. To find out if your device is compatible, see http://www.fitbit.com/devices.
How does my tracker sync with the Fitbit app?
The Fitbit app uses Bluetooth Low Energy (BLE) technology to sync with your Fitbit tracker. To initiate a sync, just open the Fitbit app.
You must have Bluetooth enabled on your mobile device or Windows 10 PC to sync your tracker with the Fitbit app. If your mobile device is in airplane mode, it will not sync until you turn off airplane mode or manually turn Bluetooth back on.

How often does my tracker sync automatically?
Your tracker syncs with the Fitbit app every time you open the app, or periodically throughout the day if you have all-day sync turned on. Some customers find that all-day sync causes the battery on their mobile device to drain too quickly. If this happens, you can disable all-day sync.
Your tracker syncs with Fitbit Connect every 15 minutes if it is near your computer and the wireless sync dongle is plugged in. Note that Fitbit Blaze™ doesn't come with a dongle. To sync a Blaze with your computer, put the tracker into the charging cable and plug the other end into a USB port.
Can I make my tracker sync at any time?
You can make your tracker sync at any time. For instructions, choose a section below. Note that if you normally sync your tracker with a mobile device and want to do so with a computer, you'll need to move the mobile device out of range or temporarily disable Bluetooth.
Fitbit app for iOS
From the Fitbit app dashboard, tap the Account tab, and then tap your tracker to see an option for syncing immediately.
Fitbit app for Android
From the Fitbit app dashboard, tap the menu icon in the top left corner, tap Devices, and then tap your tracker to see an option for syncing immediately.
Fitbit app for Windows 8.1
From the Fitbit app dashboard, tap the menu icon (three dots) in the bottom right corner to see an option for syncing immediately.
Fitbit app for Windows 10
From the Fitbit app dashboard, tap or click the Account tab at the top, and then tap or click your tracker to see an option for syncing immediately.
If you're using the Fitbit app for Windows 10 on your computer, your tracker syncs each time you open the app and whenever you manually sync. If your computer is equipped with Bluetooth 4.0 Low Energy (BLE), the Fitbit app for Windows 10 does not require a wireless sync dongle.
Fitbit Connect (Mac or PC)
Bring your charged tracker near to the plugged-in dongle or base station. You may need to press your tracker’s button or tap it to wake it up.
Click the Fitbit Connect icon.
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.
To see when the most recent sync occurred, click the gear icon in the top right corner of the fitbit.com dashboard.
How often does my tracker need to sync?
A daily sync is recommended but not required. All Fitbit trackers can record detailed minute-by-minute data for seven days, so if you're able to sync weekly your complete minute-by-minute-data will be available. Note that Fitbit Alta™ records minute-by-minute data for only five days. Daily totals are stored for 30 days for all trackers, so if you're only able to sync monthly you can still see your daily totals on your dashboard.
Fitbit Surge™ can store a maximum of 35 hours of GPS data. If you try to track more than 35 hours worth of GPS data without syncing, older data will be deleted to make room for new data. To ensure that all your GPS data is saved, sync your Surge regularly.
Do Android devices have any special considerations?
Android devices must have both a BLE radio and software support. BLE is an optional component of Bluetooth 4.0, meaning not all devices with Bluetooth 4.0 include BLE. Some devices have the hardware but not the software, while others have both but software bugs prevent it from working. If you're buying an Android device to use with the Fitbit app, make sure the device appears on our supported devices list at http://www.fitbit.com/devices. For a list of known issues, see Which Android devices have known issues with the Fitbit app?
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. Note that if your mobile device is "bonded" to your tracker, you'll need to disable the bond before you can sync with another device or a computer. For details, see Why is my tracker only syncing with one mobile device?
