Apple Health Integration

Overview

iOS WHOOP members can connect to Apple Health to sync their Recovery, Strain, and Sleep metrics across platforms.

  • Recovery: WHOOP can automatically sync recovery metrics including Resting Heart Rate, Blood Oxygen (SpO2), and Respiratory Rate to Apple Health.

  • Strain: WHOOP can automatically sync activities between Apple Health and WHOOP. Members who record workouts with a smart watch, train with a bike computer, or use other connected fitness/wellness apps can have their workouts and meditations automatically imported from Apple Health to WHOOP. WHOOP utilizes the imported activity’s start/end time and classification alongside the WHOOP-tracked heart rate to automatically log activities in the WHOOP app.

  • Sleep: WHOOP can automatically sync sleep details to Apple Health.

  • Body measurements: WHOOP can automatically sync weight and height from Apple Health to improve calorie calculation accuracy.

What Data is Imported & Exported?

Our Apple Health integration supports a bidirectional flow of data between WHOOP and Apple Health. Once another app or product has synced their activity data to Apple Health, the WHOOP app will import that data. In most cases, this will take place right after the activity is logged, but in some cases, we may not import data until you open the WHOOP app.

Imported from Apple Health to WHOOP

  • Workouts
  • Workout routes
  • Active Energy
  • Distance
  • Mindful Minutes
  • Weight
  • Height

Members can choose to contribute additional health, nutrition, and fitness data from Apple Health to WHOOP to aid in the research and development of new features.

Exported from WHOOP to Apple Health

  • Workouts
  • Active Energy
  • Heart Rate
  • Sleep
  • Resting Heart Rate

FAQ – Import

How is WHOOP using my data?
By importing data from Apple Health, WHOOP seamlessly creates activities utilizing the imported activity’s start/end time and type. As a result, we can perform our analytics faster and enable members to more quickly dive into their activity data. In addition to activity data, WHOOP imports body measurements to improve accuracy of calorie calculations and keep profile information up-to-date.

I’ve enabled the integration but I’m not seeing activities that I recorded with other apps / devices getting auto-created in WHOOP. Why is that?
First, ensure that all "read" permissions for WHOOP within Apple Health have been toggled on: navigate to the Apple Health app > profile icon > Apps > WHOOP. Then, go back to the other apps and ensure that you've enabled them to "write" data to Apple Health. Please note that some apps/devices require you to open their app after completing an activity in order for them to write their activity data to Apple Health. For example, Garmin Watch and Peloton Bike activities are only synced to Apple Health after you open the Garmin Connect and Peloton App on your iPhone.

Can imported Apple Health activities be edited within the WHOOP app?
Yes; all activities (imported or otherwise) can be edited for 30 days.

Will imported Apple Health activities override activities I record using Strain Coach?
No; if Strain Coach is in session, we will not override it with an imported activity.

What happens if WHOOP auto-detects an activity, and then an activity is imported from Apple Health that overlaps with the existing activity?
In order for WHOOP to utilize an imported activity in place of an existing auto-detected activity, one or more of the following three cases must be true:

  1. The imported activity has overlapping (yet different) time bounds as the existing WHOOP auto-detected activity (e.g. imported activity was from 3-4pm and the auto-detected activity was from 2:30-4:30pm).

  2. The imported activity has a different activity type (e.g. imported activity type is “basketball” and the auto-detected activity type was “activity”). Note: if the imported activity has a type of “unknown” or “other”, we will not utilize the imported activity’s type and will keep the auto-detected activity type.

  3. The imported activity has GPS data associated to it.

We will update the existing auto-detected activity with the imported activity’s time bounds, type, and GPS data if available.

What happens if I manually add or edit an activity, and then an activity is imported from Apple Health that overlaps with the existing activity?
In this case, we will not use the imported activity’s details. As a general rule of thumb, if you manually add or edit an activity, WHOOP will not update that activity with our own algorithmically determined or external data.

If I delete an activity in Apple Health, will it be deleted it in WHOOP as well?
If an activity is deleted in Apple Health, we will not delete that activity within WHOOP.

How much of my Apple Health history will be imported?
Upon enabling the integration, we import activities from the last 30 days and create activities from the past day. Afterwards, we import and create activities from the last 30 days.

The start/end times for my activity differ from the app that recorded the activity. Why is that?
The time bounds that WHOOP uses for imported activities are the start and end times present in Apple Health, which depends solely on how other applications write their activity data to Apple Health. For example, Garmin Connect writes “Total time” (and not Elapsed time or Moving time) to Apple Health, thus any activities from Garmin Connect → Apple Health → WHOOP will use “Total time”.

My calories burned changed since enabling the integration. Why is that?
If you have apps or smart scales that share your weight to Apple Health, WHOOP will import your weight and update your profile. Given weight is an input to your overall calorie burn, changes in weight likely affect how many calories you burn. Check out this article on calorie calculation for more information.

Why does it take longer for my Mindful Minutes to be imported?
Some applications report Mindful Minutes for functionality that helps you fall asleep, and this can interfere with our sleep auto-detection. With this in mind, we wait for your data to be caught up before importing a mindful activity to ensure that you were not in fact sleeping.

Will GPS data and associated performance metrics be imported and displayed?
We will import GPS data when available and calculate/display performance metrics (e.g. distance, pace/speed) from that GPS data. This directly mirrors the functionality of Strain Coach with GPS enabled. In the future, we may import and display performance data regardless of the presence of GPS data.

Given WHOOP calculates and displays distance and pace/speed based on GPS data, there may be differences between the distance and pace/speed shown in WHOOP versus the values from external sources.

Note: in order for WHOOP to import GPS data from other devices/apps via Apple Health, those apps must share GPS data (specifically the “Workout Routes” permission) with Apple Health. You can check if an app shares GPS data by navigating to the Health app, tapping your profile icon, tapping Apps, and then viewing the app's "write" permissions.

What happens if I have both the Apple Health and Strava integrations enabled?
We have logic in place to avoid duplication of posts to Strava for any activities that we import from Strava. For example, for activities recorded with the Strava app or recorded via another app that posts to Strava, WHOOP will not post that same activity to Strava (given the source of the activity was Strava).

Please note that some apps/devices (e.g. Garmin, Peloton, etc) write data to both Strava and Apple Health. In these cases, it is possible that WHOOP will import multiple activity instances from Apple Health for the same activity – one instance that Strava shared to Apple Health, and another that the original app/device shared to Apple Health. Our deduplication logic covers the case of Strava sharing the activity to Apple Health prior to the other app/device sharing the activity to Apple Health.

Why am I not seeing my Meditation or Stretching activities exported from WHOOP to Apple Health?
Recovery activities such as Meditation and Stretching are currently not exported from WHOOP to Apple Health. This functionality may be added in the future, though.

FAQ – Export

I’ve enabled data from WHOOP to be shared, but it’s not being presented in the Apple Health app. How come?
Many sources/apps can share data to Apple Health. When multiple sources share data to Apple Health, it’s possible that only one data source will be shown based on the priority order in the Apple Health app. If you notice that your WHOOP data is not appearing in Apple Health but you’ve enabled sharing, you likely need to update the priority order of data sources so that WHOOP is first priority. Unfortunately, this must be done for each subcategory of data within Apple Health as there is no way to update this priority for all at once. Here are Apple’s instructions for editing the priority order:

  1. Open the Health app, then tap the Browse tab.
  2. Tap a category (e.g. Vitals), then tap a subcategory (e.g. Respiratory Rate).
  3. Scroll down, then tap Data Sources & Access.
  4. Tap Edit.
  5. Scroll down to Data Sources.
  6. Touch and hold the Change Order button (three horizontal lines) next to WHOOP, then drag it up to the top of the list.

  7. To turn off a data source so that it doesn't contribute any more data for that category, tap the checkmark next to the source.
  8. Tap Done.

For more information, refer to Apple’s support article: Prioritize data sources in Apple Health.

I’m seeing duplicate activities in Apple Health across WHOOP and other apps. Why is that happening?
If you have set up both the import & export of workouts between WHOOP and Apple Health, it is possible that you will see multiple instances of the same activity within Apple Health. Apple Health does not double count calories, distances, etc; they use the prioritization system noted above to determine which data to use/surface.

You may see multiple instances of an activity in Apple Health in the following flow/case:
1. Activity is recorded with another app and is written to Apple Health
2. WHOOP imports this activity and creates an activity in WHOOP (using WHOOP heart rate to calculate calories, Strain, etc)
3. WHOOP writes the activity to Apple Health

In this case, there are two instances of the same activity in Apple Health; one with WHOOP metrics associated with it, one without. Given Apple’s prioritization framework outlined above, you can choose which data source Apple Health prioritizes/uses in showcasing Active Calories, Workouts, etc displayed in their app.

What happens if my sleep or activity is exported to Apple Health, and then I update or delete that sleep or activity within WHOOP?
If any previously exported sleeps or activities from WHOOP to Apple Health are updated or deleted within WHOOP, we will update the sleep / activity within Apple Health with the updated details.

I don’t see my HRV in Apple Health. Why is that?
Apple Health tracks HRV using SDNN, while WHOOP calculates HRV using RMSSD. While the values may trend similarly, the absolute numbers are inherently different. For more information, check out these resources: National Center for Biotechnology Information and Frontiers in Public Health.

Why am I not seeing Heart Rate data being exported from WHOOP?
WHOOP exports Heart Rate data to Apple Health for activities; HR data from throughout the day is not exportable to Apple Health. Thus, if an activity was not recorded on WHOOP, the corresponding Heart Rate data would not be available within Apple Health.

Can I disable WHOOP from writing workouts to Apple Health, but keep having WHOOP write other metrics?
Yes; in your Apple Health settings, you can toggle off “Workouts” from the write permissions section. Keep in mind that by disabling WHOOP from writing Workouts to Apple Health, WHOOP will also not write Active Energy (i.e. Calories) or Heart Rate to Apple Health given WHOOP only writes those values to Apple Health as associated data to a Workout.

FAQ – General

I just uninstalled and then reinstalled the WHOOP app. Do I have to re-enable the Apple Health integration?
Yes – if an app is uninstalled, iOS removes any Apple Health permissions that were previously granted. You will need to re-enable the Apple Health integration by navigating to the menu icon in the bottom-right corner of the app > Integrations > Apple Health > Connect > select permissions > Allow.

I've noticed that my calories burned (on WHOOP) are much lower than when compared to other wearables. Why is this?
To learn more about how WHOOP estimates and calculates your daily burned calories, visit our locker post: The Science of Calorie Tracking and our support article, How does WHOOP calculate calories burned?

Is it possible to delete my WHOOP data out of Apple Health?
Yes – you can easily delete data from Apple Health at any point in time, either for a specific data category or altogether.

  • To delete WHOOP data out of Apple Health for a specific data category (e.g. Active Calories): navigate to the Health app, tap Browse at the bottom, tap the category of choice (e.g. Activity), tap the data category of choice (e.g. Active Energy), scroll down and tap Data Sources & Access, scroll down and tap WHOOP, then tap Edit in the top right corner. From here, you can select certain data points to delete, or you can tap Delete All in the top left corner to delete all data points for the specific data type you’ve selected.

  • To delete WHOOP data out of Apple Health for all categories of data: navigate to the Health app, tap your profile icon in the top right corner, tap Apps, tap WHOOP , tap Data from “WHOOP”, tap Delete All Data from “WHOOP”, then confirm deletion when prompted.

What else do I need to know about Apple Health?
Apple Health essentially acts as an “air traffic controller of health data;” iPhone users can let apps write varying types of data to Apple Health (including a smartwatch, a bike computer, a fitness app, a health-tracking app, etc), and similarly can allow apps to read data from Apple Health.

By writing your WHOOP data to Apple Health, other apps can then read/import that data if you’ve granted them that access. Apps can write varying amounts of detail to Apple Health; for example, some apps may only include the start time, end time, and activity type when they write a workout to Apple Health, whereas some apps might also include the weather, elevation gain, and distance as metadata on the workout. In both cases, apps that read/import workouts from Apple Health can retrieve this data when it’s available.

Example: if you grant Nike Run Club access to write workouts to Apple Health, and you grant WHOOP access to read workouts from Apple Health, a run recorded with NRC can flow seamlessly from their app → Apple Health → WHOOP, whereby WHOOP can receive the run data that Nike Run Club wrote to Apple Health in the first place (based on which specific “write permissions you granted to NRC, and which specific “read” permissions you’ve granted to WHOOP).
