Connecting Fitbit to Apple Health in three steps

You can send your Fitbit data directly into Apple Health so both apps track your activity in one place. The connection happens through the Fitbit app on your iPhone — you authorize Apple Health once, and the data flows automatically after that. The whole process takes about five minutes and requires no settings changes on your Fitbit device itself.

Apple Health acts as a central hub that collects data from many fitness apps and devices. When you link Fitbit, Apple Health receives your daily steps, distance, calories burned, heart rate, and sleep data. You control what information flows in each direction, and you can disconnect at any time without losing your history in either app.

Key Takeaways

  • The connection happens entirely in the Fitbit app on your iPhone — you do not need to open Apple Health to set it up.
  • You will be asked to allow Fitbit to read and write specific data types to Apple Health, and you can refuse individual categories if you want.
  • Once linked, your Fitbit data syncs automatically to Apple Health whenever your Fitbit syncs to your phone.
  • You can disconnect Fitbit from Apple Health at any time by removing the permission in the Fitbit app or by revoking access in Apple Health settings.

Step 1: Open the Fitbit app and go to permissions

Launch the Fitbit app on your iPhone and tap the profile icon in the bottom right corner. Scroll down until you see "Health" or "Apple Health" — the exact label depends on your Fitbit app version, but it will be in the account settings area, not in the main menu.

If you do not see an Apple Health option, update the Fitbit app from the App Store first. Older versions may not support the connection. Once you update, return to your profile settings and look again.

Step 2: Tap the toggle to turn on Apple Health

When you tap the Apple Health setting, the Fitbit app will ask you to confirm that you want to allow Fitbit to access Apple Health. A screen will appear listing the data types Fitbit wants permission to read and write — things like steps, distance, heart rate, and sleep.

You will see two columns: one showing what Fitbit will send to Apple Health (write), and one showing what Fitbit will read from Apple Health (read). You do not have to accept all of them. If you do not want your sleep data in Apple Health, for example, you can uncheck that box before confirming.

Step 3: Confirm the permission request

Tap "Allow" or "Turn On" at the bottom of the screen. Your iPhone may ask you to authenticate with Face ID, Touch ID, or your Apple ID password — this is Apple's security check to make sure you are the account owner. Complete that step, and the connection is active.

Your Fitbit data will not appear in Apple Health when ready. It syncs the next time your Fitbit syncs to your phone, which usually happens within a few minutes if Bluetooth is on and your phone is nearby. If you do not see data after 10 minutes, force-close and reopen the Fitbit app to trigger a manual sync.

What data flows between the apps

By default, Fitbit sends steps, distance, active minutes, calories burned, heart rate, and sleep data to Apple Health. If you wear a Fitbit with a built-in GPS, route and elevation data also transfer. Apple Health can send data back to Fitbit — for example, if you log a workout in Apple Health's Workout app, Fitbit will see it and count it toward your daily activity.

The data that appears in Apple Health comes from your Fitbit device, not from third-party sources. If you use other apps to log workouts or meals, those do not automatically flow to Fitbit unless you set up separate connections with those apps. Apple Health is the middleman, but it does not merge data from apps you have not explicitly connected.

Disconnecting Fitbit from Apple Health

If you want to stop sharing data with Apple Health, open the Fitbit app, go to your profile, and tap the Apple Health setting again. Toggle it off. The connection stops when ready, but your historical data remains in both apps — disconnecting does not erase anything.

You can also revoke permission from Apple Health's side. Open the Health app, tap your profile picture in the top right, scroll to "Apps," find Fitbit, and tap it. Then tap "Delete All Data" if you want to remove Fitbit's data from Apple Health, or just tap "Turn Off" to stop the connection without deleting history. Both methods work; use whichever is easier for you.

Troubleshooting a failed connection

If the Apple Health option does not appear in your Fitbit app, check that you are running iOS 12.2 or later on your iPhone. Go to Settings > General > About and look at the iOS version number. If it is older, update your phone first.

If the connection fails after you tap Allow, make sure Bluetooth is on and your Fitbit is synced to your phone. Open the Fitbit app's main screen and wait for the sync icon to stop spinning. Then return to settings and try again. If you still see an error, sign out of the Fitbit app completely, sign back in, and repeat the setup.

If data is not appearing in Apple Health after 24 hours, check that you did not accidentally uncheck all the data types during setup. Go back to the Apple Health setting in Fitbit and verify that at least one category is toggled on. If everything looks correct, try disconnecting and reconnecting — sometimes a fresh authorization fixes a stalled sync.

Frequently Asked Questions

Does linking Fitbit to Apple Health drain my battery?

No. The connection uses the same Bluetooth sync that Fitbit already does with your phone, so there is no extra battery cost. Apple Health runs in the background on your iPhone and does not require active monitoring.

Can I link multiple Fitbits to the same Apple Health account?

Yes. If you have more than one Fitbit device, you can link them all to the same Apple Health account through the same Fitbit app. Data from all devices will flow into Apple Health, though you will see it grouped by device type rather than by individual tracker.

Will my Fitbit data show up in the Apple Health app when ready?

No. Data appears after your Fitbit syncs to your phone, which usually happens within a few minutes of the connection being active. If you want to see it sooner, open the Fitbit app and manually trigger a sync by pulling down on the main screen.

What happens to my data if I disconnect Fitbit from Apple Health?

Your historical data stays in both apps. Disconnecting stops new data from flowing in, but it does not erase anything that already synced. You can reconnect later and pick up where you left off.

Can I choose which data types Fitbit sends to Apple Health?

Yes. During setup, you can uncheck any data category you do not want to share — for example, you can allow steps but refuse sleep data. You can change these settings later by going back to the Apple Health option in your Fitbit profile.
