Lost your Fitbit and bought another as a replacement? Decided to replace an old Fitbit and update your Fitbit to the latest model?

Received a replacement Fitbit covered under Fitbit’s warranty program? Or did your Fitbit break down, and you purchased a new Fitbit to take its place? All of these are reasons why folks replace their Fitbits.

If you are wondering how to get that new device to work just like the old one, the good news is that it’s relatively easy to replace your Fitbit and retain all your activity data from the old Fitbit!

The most important step is to make sure you connect your replacement (or new) Fitbit device to your existing Fitbit account.

It’s actually your Fitbit account that stores your activity data, not the individual device.

Why replace a Fitbit device and not just add another Fitbit to my account?

If your new Fitbit is a warranty replacement for a troublesome or broken device or you’re replacing a lost device with the same model, you should do a one-to-one replacement.

However, if you upgraded or changed your Fitbit device model, you might consider simply adding that new device to your list of account devices.

Having more than one device gives you some flexibility, especially if you want to use a different model for varying activities–like one worn for the office and a different model used for swimming or at the gym.

When you connect more than one Fitbit to your account, it aggregates and syncs the data across devices. So your Fitbit dashboard shows you the sum of all your data!

Connect any replacement to the same Fitbit account

If you replace your existing Fitbit, make sure you connect it to your current Fitbit account–do not create a new Fitbit account.

That means logging in as an Existing User with the same Fitbit account credentials you used on that older Fitbit. three different Fitbit models

Having multiple Fitbits connected to your account sounds like a good idea. Sadly, it’s often not possible.

Unfortunately, while Fitbit does support multi-trackers on a single account, it does not offer this feature for all of its devices.

In particular, most of the newest models (like the Versa, Charge, and Inspire series models) do not allow for multiple device support.

These listed devices allow you to connect only one of these devices at a time to your account: The Fitbit Charge 3 & 4, Fitbit Ionic, Fitbit Inspire series, Fitbit Sense, and Fitbit Versa series.

So if you’re replacing or upgrading from one of those listed devices, you cannot keep your old device on your account!

What’s the difference between the Fitbit app and Fitbit Connect? Fitbit app on iPhone

To set up your replacement (or new) Fitbit, you need to use Fitbit’s app or Fitbit Connect.

  • The Fitbit app is compatible with Android and iOS (Apple) phones and tablets running iOS 12.2 and above and Android 7.0.
    • There’s also a Fitbit app for Windows 10 computers but not older Windows versions or Macs.
    • The Fitbit app supports most models including newer models like the Sense, Versa Series, Ionic, Charge Series, and Inspire series.
  • For Macs and older Windows versions, set up Fitbit devices using a program called Fitbit Connect. Fitbit Connect does not support many newer model Fitbits.
    • Fitbit connect currently supports Zip, Ace 2, Aria & Aria Air (not the Aria 2), Fitbit One, Alta, Flex & Flex 2, Charge HR & 2, Blaze Surge models only.
    • It works with Bluetooth to connect to your Fitbit device. If your computer does not have Bluetooth capability, you need a separate wireless dongle.

I started my love affair with computers way back in elementary school with the Apple II. Since then, I've worked with technology in my career as a media educator and videomaker. I have an MFA in media making from Temple University, where I also taught undergrads as an adjunct faculty member. So I know a thing or two about teaching others and creating how-to guides! After a cancer diagnosis, I turned to mobile technology like my Apple Watch to help me monitor my health throughout my chemotherapy treatment and later, to regain my wellness once in remission. I love sharing how to understand and use mobile tech, like smartwatches and phones, as a tool for empowerment to live our best and healthiest lives!
