    How to Sync Garmin Connect With Apple Health

    By Sonar May 21, 2026

    This guide explains how to sync Garmin Connect with Apple Health on iPhone, including what data transfers, why Apple Health numbers may not match Garmin, and how to troubleshoot common sync issues.

    How to Sync Garmin Connect With Apple Health

    Quick Answer


    To sync Garmin with Apple Health, open the Garmin Connect app, go to More → Settings → Connected Apps → Apple Health, then enable the health categories you want Garmin to share.


    The key thing to understand is that this integration mainly sends supported data from Garmin Connect to Apple Health. It is not a full two-way sync that imports all Apple Health or Apple Watch data back into Garmin Connect.


    That means Garmin can help populate Apple Health with data like steps, workouts, heart rate, sleep, active energy, walking/running distance, flights climbed, weight and related health metrics. But if you are trying to move Apple Watch data into Garmin Connect, Apple Health alone usually will not solve that.


    What Garmin Data Syncs to Apple Health?


    Before diving in, it helps to know what actually transfers. Garmin Connect pushes the following data categories to Apple Health:


    • Steps and distance

    • Heart rate (resting and active)

    • Workouts (runs, rides, swims, strength sessions, etc.)

    • BMI and Body Fat Percentage

    • Sleep analysis

    • Flights climbed

    • Active energy

    • Resting energy

    One important note: the native Garmin + Apple Health connection is primarily one-way from Garmin Connect to Apple Health. Apple Health does not provide a full native sync back into Garmin Connect or your Garmin device.


    How to Sync Garmin With Apple Health


    Follow these steps on your iPhone:


    1. Open the Garmin Connect app.

    1. Tap More in the bottom-right corner.

    1. Go to Settings.

    1. Tap Connected Apps.

    1. Select Apple Health.

    1. Tap Connect with Apple Health.

    1. Choose the data categories you want to share.

    1. Tap Allow to confirm permissions.

    1. Sync your Garmin watch or device with Garmin Connect.

    1. Open Apple Health and check the relevant categories.

    If Garmin Connect does not appear in Apple Health, start the setup from the Garmin Connect app first. Users note that the connection often works better when initiated through Garmin Connect rather than from Apple Health settings.


    Why Garmin and Apple Health Numbers May Not Match


    It is normal for Garmin Connect and Apple Health to show slightly different numbers. The most common reason is data source priority.


    Apple Health can receive data from multiple places, including:


    • iPhone

    • Apple Watch

    • Garmin Connect


    • Smart scales

    • Workout apps

    If multiple apps are writing the same metric, Apple Health decides which source to prioritize. For example, your iPhone may be listed above Garmin Connect for steps, which can cause Apple Health to show iPhone step data instead of Garmin step data.


    How to Prioritize Garmin in Apple Health


    To make Apple Health prioritize Garmin data:


    1. Open the Health app.

    1. Tap Browse.

    1. Choose a category, such as Activity.

    1. Tap Steps.

    1. Scroll down to Data Sources & Access.

    1. Tap Edit.

    1. Move Garmin Connect higher in the list.

    1. Tap Done.

    Repeat this for any metric where Apple Health and Garmin Connect do not match.

    It's also worth toggling Garmin's Apple Health permissions off and back on again to help refresh the connection.


    Getting More from Your Data


    Once Garmin Connect is writing to Apple Health, other apps with Apple Health read permissions may be able to access compatible Garmin metrics. This can be useful if you use separate apps for nutrition, sleep, workouts or broader health tracking. Apps like Sonar, available on iOS and web, can help organize health data from multiple sources and also offer a direct Garmin integration for users who prefer to connect Garmin separately instead of relying only on Apple Health as the middle layer.


    Frequently Asked Questions (FAQ)


    Can Garmin sync with Apple Health?


    Yes. Garmin Connect can sync supported Garmin data with Apple Health when you enable the Apple Health connection in Garmin Connect.


    Why does Apple Activity show "Chart Unavailable" for Garmin workout heart rate?


    Garmin syncs all-day heart rate data to Apple Health, but for timed activities it may only send high and low heart rate values instead of a detailed heart rate stream. As a result, the app may show "Chart Unavailable" for these types of heart rate graphs because there is not enough detailed activity heart rate data to display.


    Does Garmin sync steps to Apple Health?


    Yes, Garmin Connect can share step data with Apple Health. If the numbers look wrong, check Apple Health's Data Sources & Access settings and move Garmin Connect higher in the priority list.


    Why is Garmin not syncing with Apple Health?


    Common causes include disabled Apple Health permissions, Garmin Connect not being connected properly, your Garmin device not syncing first or Apple Health prioritizing another data source.


    Does Apple Health sync back to Garmin Connect?


    The native Garmin and Apple Health connection is primarily one-way from Garmin Connect to Apple Health. Apple Health does not provide a full native sync back into Garmin Connect or your Garmin device.
