Enabling Oura Nap Data Sync to Apple Health

[d108]

Problem Statement

The Oura app currently saves sleep heart rate data to Apple Health when the type is long_sleep. However, heart rate data recorded during naps, categorized under type of sleep, is not being saved according to API access at:

https://api.ouraring.com/v2/usercollection/sleep/

This results in a gap in the health data available to HeartBond users.

For more context, Oura has acknowledged this issue in a Reddit post.

Proposed Solution

We aim to bridge this gap by offering a feature that allows users to save their nap-related heart rate data to Apple Health for viewing in HeartBond.

Technical Details

• Data Similarity: Except for the type, the heart rate sample data for both long_sleep and sleep are identical.

• User Permission: To implement this feature, we will request write access to Apple Health for users who opt-in to synchronize this specific data.

Implementation Steps

1. User Consent: Prompt users with a dialog box asking for permission to write nap data to Apple Health.
2. Data Retrieval: Fetch the heart rate data from Oura categorized under type of sleep.
3. Data Transformation: Convert the fetched data into a format compatible with Apple Health.
4. Data Sync: Write the transformed data to Apple Health under the appropriate category.

Benefits

• Fills a data gap in Apple Health for users who take naps.
• Provides a more comprehensive view of heart rate data for better health tracking.

Security Considerations

• Ensure that the write access request clearly specifies the scope of data being synchronized.

Alternative Path

• Instead of writing data to the Health data store, we could add it to our CloudKit-synced database and display it in the app. This would be a simpler implementation, but would not allow users to view their nap data in Apple Health.

We welcome feedback and contributions to make this feature as effective and secure as possible.
