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.
1) 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, download RunGap from the App Store, connect a Garmin account, and import workouts into Apple Health. To prevent duplicate entries, Garmin’s native workout syncing should be disabled. This can be done by navigating to the Apple Health app > Browse > Activity > Workouts. Scroll to the bottom and tap “Data Sources & Access,” locate Garmin Connect under your “Data Sources,” and toggle off the option to write workout data to Apple Health.
2) Add HRV Data 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 must manually enter it.
To do this, navigate to the Apple Health app > Browse > Heart > Heart Rate Variability > tap 'Add Data' in the top right corner, and manually enter a reading found in Garmin Connect at a reasonable sleep time such as 3:00 AM.
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.
Preventing Duplicate Workout Data
If both Garmin and Apple Watch are used, workouts may be logged twice in Apple Health, leading to duplicate entries. To prevent this, Garmin’s workout syncing should be turned off in Apple Health while ensuring RunGap imports Garmin workouts instead.
To disable Garmin’s workout syncing, navigate to the Apple Health app > Browse > Activity > Workouts. Scroll to the bottom and tap “Data Sources & Access,” locate Garmin Connect under your “Data Sources,” and toggle off the option to write workout 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.
