To transfer a Fitbit Flex to another person, you must first erase the device to remove your personal data, then have the new owner set it up in their own Fitbit account and sync it from the Fitbit app. This process ensures the new owner can start fresh with their own fitness tracking history and settings.
Before you transfer your Fitbit Flex
The official reason to erase a Fitbit Flex before giving it to another person is to remove apps, stored data, personal information, payment cards on supported devices, and saved settings. A critical, often-missed step is to also remove the Flex from the old phone's Bluetooth settings. This prevents the old phone from automatically reconnecting to the device and interfering with the new owner's setup. Remember to inform the new owner about any privacy concerns related to the Fitbit Flex, such as linking it with third-party apps or sharing data publicly.
How to set up the Fitbit Flex on a new account
The new owner must pair the Flex with their own Fitbit account. The verified steps are:
- Open the Fitbit app on the new owner's phone or tablet.
- Go to the Today tab.
- Tap Devices.
- Follow the on-screen prompts to add the device.
The Fitbit app requires a minimum phone operating system version. For iPhone and iPad, the app requires iOS 15 or higher on compatible devices. For Android, the documented minimum version varies across Google's support pages, listing either Android 9 or higher or Android 11 or higher. For iOS, the requirement may be iOS 16.4 or higher depending on the support page consulted. The new owner should ensure their phone meets the requirements for their specific device.
How to sync the Fitbit Flex to the new account
After setup, the new owner performs an initial sync to pull data into their account. The verified path is:
- Open the Fitbit app.
- Tap the Today tab.
- Tap your profile picture.
- Tap your device image.
- Use Sync Now.
Troubleshooting a Fitbit Flex transfer
If the setup fails, the primary fix is to remove the Fitbit device from the list of connected Bluetooth devices on the phone or tablet, then repeat the setup process. If the sync process fails, check the internet connection and try again. To reset the Fitbit Flex, locate the small pinhole on the back of the device, insert a paperclip or SIM card removal tool, and hold down the button for about 10-15 seconds until the Fitbit logo appears. If the Fitbit Flex battery is low or needs replacement, consider replacing it before the transfer for optimal usage. For further assistance, consult Fitbit support and ownership help (Fitbit Support, Repairs and Device Identification).
