Fitbit smartwatches are excellent and much cheaper alternatives to the Apple Watch. It’s reasonable to consider the Sense 2 and Versa 4 viable devices alongside the iPhone. But can you connect Fitbit devices to Apple smartphones? We’ll answer all that and more below.


You can use Fitbit's smartwatches and fitness trackers with most iPhones. To use a Fitbit with an iPhone, download the Fitbit app, set up your account, and pair your device.


Fitbit and iPhone support: What’s the story?

Even though Fitbit is now under Google ownership, the company’s devices still support most iPhones.

The two devices will happily work if the iPhone in question runs at least iOS 15. This means you can use a Fitbit with your phone if you own an iPhone 6S series or newer. If you have a phone not running at least iOS 15, you won’t be able to use your Fitbit with it.

How to connect your Fitbit to your iPhone

  1. First, you’ll need to download the Fitbit app on your iPhone. You’ll use it to connect your Fitbit device to your phone.
  2. Open the Fitbit app and tap Log In if you have a Fitbit account, or Sign in with Google if you have a Google account.
    • To set up a new account, tap Continue as a new user then select Create account.
  3. Once logged in, the app will suggest that you pair your Fitbit. Follow the instructions on screen to pair your Fitbit to your iPhone.
    • Ensure that your Fitbit device is connected to its charger, and that your Bluetooth is activated on both devices.

Fitbit’s future compatibility with iPhones

Although Fitbits and iPhones work well together, it’s unclear if this will still be the case in the future.

New Fitbit buyers must create a Google account to use Fitbit wearables. However, those with existing Fitbit accounts can choose to use said accounts “until at least the beginning of 2025,” when the support of Fitbit accounts ends and users will be forced to migrate to a Google account.

If you’re an iPhone owner considering a new Fitbit, keep this change in mind. That said, there is no shortage of excellent Fitbit alternatives.


Check if your iPhone is running the latest version of iOS and is supported by Fitbit. Other troubleshooting steps should include restarting both devices and restarting Bluetooth.

No, these apps are identical on both platforms and provide similar functionality.

If you don’t have the budget for an Apple Watch, the Sense and Versa 3 are good alternatives. Apple fails to offer affordable wearables, so iPhone owners may consider the Inspire 3 as a cheap fitness tracker. Granted, you won’t get that seamless Apple ecosystem functionality between watchOS and iOS. Fitbit devices include more detailed health tracking and will go further between charges than the Apple Watch.
