Garmin, Oura, and Third-Party Wearables

Athlytic integrates with Apple Health, so any device that syncs data to Apple Health should technically work. However, most third-party wearables do not sync correctly or in real-time, leading to delays and potential gaps in data. Because of this, Athlytic works best with an Apple Watch, which provides the most reliable and up-to-date information.

That said, many users successfully use other wearables like Garmin or Oura with Athlytic by leveraging workarounds.

Garmin

Garmin watches don’t fully integrate with Apple Health, meaning Athlytic cannot directly access all Garmin data. While some data syncs to Apple Health via Garmin, more advanced data — such as HRV, and detailed workout data — requires the following workarounds.

We have not tested these workaround ourselves, but many of our users have reported success.

These workarounds may also work for other similar wearables.

Workout Data - Sync Workouts with RunGap

To improve workout data accuracy, using RunGap is recommended. When Garmin syncs workouts directly to Apple Health, some data may be missing or simplified. Heart rate data may not include all recorded values, power meter readings may be excluded, and detailed workout metrics like heart rate zones and cadence may not transfer properly.

RunGap helps by importing more complete and higher-frequency workout data into Apple Health.

To set it up:

1. Download RunGap from the App Store.
2. Connect your Garmin account.
3. Import workouts into Apple Health.

Prevent duplicate entries:

Disable Garmin’s native workout syncing:

• Go to Apple Health → Browse → Activity → Workouts
• Scroll to Data Sources & Access
• Tap Garmin Connect and disable the option to write workout data to Apple Health.

HRV Data – Sync or Add to Apple Health

Garmin does not sync HRV to Apple Health, even though it tracks HRV internally. Athlytic needs HRV data for accurate Recovery tracking, so you have two options:

Option 1: Manually Add HRV Data to Apple Health

1. Open the Apple Health app
2. Tap Browse → Heart → Heart Rate Variability
3. Tap ‘Add Data’ (top right corner)
4. Manually enter an HRV reading from Garmin Connect at a time you were asleep like 3:00 AM.

Important: If you use this method, do not enable “Use RMSSD for HRV” in Athlytic. That setting depends on raw beat-to-beat data, which manually added values don’t include.

Option 2: Use FitnessSyncer to Automatically Sync HRV

Some users have reported success using FitnessSyncer to bridge Garmin HRV data into Apple Health.

• Connect your Garmin Connect and Apple Health accounts in FitnessSyncer.
• Configure it to sync HRV (if available via your Garmin model/API).
• This may allow more automation and reduce manual entry.

Note: Garmin limits access to some data via its API, so FitnessSyncer may not always be able to transfer HRV. Results vary by device and settings.

Other Wearables

The above workaround for Garmin may be worth trying with other wearables if the wearable also syncs some of its data to Apple Health.

Oura

If you use Oura, you can set it as your “Preferred Sleep Tracker” in the More tab of Athlytic. However, while Oura writes sleep data to Apple Health, it does not write HRV data. This means Athlytic will not have your overnight HRV data unless you wear your Apple Watch to sleep or use a workaround.

Some users have reported success with a community-sourced method for adding Oura HRV data to Apple Health. We have not tested this workaround ourselves, so use it at your own risk. If you’re interested, you can find details here:  Updated Workaround for Adding Oura Data to Apple Health.

If you use this workaround, DO NOT enable “Use RMSSD for HRV” in Athlytic. This setting relies on raw beat-to-beat samples, so it will not recognize HRV data added through the workaround.

If none of these troubleshooting steps resolve the issue, consider reaching out to Athlytic support for further assistance.
