Yes, Fitbit syncs to Apple Health, but only through the official Fitbit app

Your Fitbit device can send data to Apple Health, but the connection works in one direction only: from Fitbit to Apple Health. You set this up inside the Fitbit app on your iPhone, not in Apple Health itself. Once enabled, your daily steps, heart rate, sleep, and other metrics flow automatically from your Fitbit to Apple Health whenever your device syncs.

The sync happens in the background after your Fitbit connects to your phone. You do not need to manually transfer data or use a third-party tool. However, Apple Health cannot send data back to Fitbit—it is a one-way street. This matters if you use other apps or devices that feed into Apple Health, because Fitbit will not see that information.

Key Takeaways

  • Open the Fitbit app, go to your profile, select your device, and toggle on "Apple Health" in the data sharing section to start syncing.
  • Fitbit sends steps, heart rate, sleep duration, calories burned, and distance to Apple Health, but not all Fitbit metrics transfer over.
  • The sync is automatic and happens whenever your Fitbit connects to your phone, with no additional setup needed after you turn it on.
  • Data flows only from Fitbit to Apple Health; Apple Health cannot push information back to the Fitbit app.

How to turn on Apple Health syncing in the Fitbit app

Start by opening the Fitbit app on your iPhone and signing in to your account. Tap the profile icon in the bottom right corner, then select your Fitbit device from the list. Scroll down until you see "Apple Health" or "Health App Integration"—the exact wording depends on your Fitbit model and app version.

Tap the toggle next to Apple Health to turn it on. The Fitbit app will ask you to confirm that you want to share data with Apple Health. You may also see a prompt asking which specific metrics you want to share—steps, heart rate, sleep, and calories are the most common. Select the ones you want, then confirm. That is all the setup required. Your data will begin syncing the next time your Fitbit connects to your phone.

Which Fitbit metrics actually sync to Apple Health

Not every number your Fitbit tracks makes the journey to Apple Health. The metrics that do transfer are steps, distance traveled, calories burned, heart rate, and sleep duration. These are the core health measurements that Apple Health is designed to receive from wearables.

Fitbit-specific metrics like active minutes, exercise sessions, or detailed sleep stages (light, deep, REM) do not appear in Apple Health. If you rely on those measurements, you will still need to check the Fitbit app itself. The same applies to Fitbit's stress score or menstrual cycle tracking—those stay in Fitbit only. This is a limitation of how Apple Health is structured, not a choice Fitbit made.

Troubleshooting when Fitbit data is not showing up in Apple Health

If you turned on the toggle but data is not appearing in Apple Health, the most common cause is that your Fitbit has not synced to your phone since you enabled the feature. Open the Fitbit app and manually sync your device by pulling down on the screen or tapping the sync button. Wait a few seconds for the connection to complete, then check Apple Health.

If data still does not appear, check that you gave the Fitbit app permission to access Apple Health. Go to your iPhone Settings, scroll to Fitbit, and tap Health. Make sure the toggle next to Apple Health is on and that at least one metric (steps, heart rate, etc.) is enabled. If you recently updated the Fitbit app, you may need to re-enable the Apple Health toggle—updates sometimes reset this setting. Restart both the Fitbit app and Apple Health if nothing else works.

What happens to historical data when you enable syncing

When you first turn on Apple Health syncing, Fitbit does not automatically send all your past data. Only new data collected after you enable the feature will sync going forward. If you want historical data in Apple Health, you will need to manually add it or use a third-party service that bridges Fitbit and Apple Health.

Some users find this frustrating if they have months or years of Fitbit history they want to see in one place. Unfortunately, there is no built-in way to backfill Apple Health with old Fitbit data through the official app. Your Fitbit app still holds all that history—it just will not appear in Apple Health unless you manually enter it.

Using Apple Health as your main health dashboard

Once Fitbit data flows into Apple Health, you can view all your metrics in the Health app alongside data from other devices and apps. Apple Health consolidates everything in one place: your iPhone's built-in motion sensors, your Fitbit, any other wearables you own, and apps like Strava or MyFitnessPal if you connect them.

This is useful if you want a single view of your daily activity, but keep in mind that Fitbit's app still has features Apple Health does not. Fitbit's app shows exercise history in more detail, lets you log food and water intake, and displays trends over weeks and months in ways Apple Health does not. Most people keep both apps open—Fitbit for detailed tracking and Apple Health for a quick overview.

Frequently Asked Questions

Can I sync Fitbit to Apple Health on Android?

No. Apple Health only exists on iPhone and iPad. If you use an Android phone, you cannot sync Fitbit to Apple Health. Android users can sync Fitbit to Google Fit instead, which is Google's equivalent health platform. The process is similar—you enable it in the Fitbit app settings—but the destination is different.

Will turning on Apple Health syncing drain my Fitbit battery?

No. Syncing to Apple Health does not use extra battery on your Fitbit device. The sync happens on your phone, not on the watch. Your Fitbit's battery life will remain the same whether syncing is on or off.

Can I turn off syncing for specific metrics?

Yes. In the Fitbit app, go to your device settings and find the Apple Health section. You can toggle individual metrics on or off—for example, you might want steps and heart rate to sync but not calories. This gives you control over what information reaches Apple Health.

Does Fitbit sync to Apple Health in real time?

Not quite. Data syncs whenever your Fitbit connects to your phone, which usually happens within a few minutes of your device collecting the data. It is fast enough for most purposes, but it is not true real-time. If you need live updates, check the Fitbit app directly.
