HealthKit Background Health Data Collection, Emergency Contacts, and Automated Alerting Feasibility

I have a few feasibility questions regarding health data processing on iOS, related to HealthKit and system capabilities:

Background Health Data Collection

Can an iOS app continuously collect and process health data in the background, including: Collecting health data from the Health app while the device is locked or in sleep mode Triggering user notifications when anomalies are detected in health data processing Are there any technical limitations? Do these capabilities require specific enterprise qualifications or additional fees? 2. Emergency Contacts Integration Can an app write or modify the system’s built-in Emergency Contacts (Medical ID)? If a user updates Emergency Contacts in iOS Settings, can the app receive a change notification or access the updated data? 3. Automated Alerting for Health Metrics Beyond Apple’s fall detection, can abnormal health metrics (heart rate, irregular rhythm, blood oxygen, etc.) trigger automated alerts such as SMS to preset emergency contacts—without requiring the user to manually open the app or only receive on-device notifications? This is a feasibility inquiry about API and system behavior, not a bug report. Any official guidance or documentation references would be greatly appreciated.

An iOS app can't continuously run in the background. For more information about iOS background execution limits, see here. For using HealthKit in background, see here. (The latter is about HealthKit in watchOS, but the situation is pretty much the same in iOS.)

Emergency Contacts is a user feature. For privacy reason, there is no API to access the information.

Given that the answer to your question 1 and 2 is no, you can't achieve the automated alerting either.

Thank you again for your previous response.

I'd like to follow up on one specific aspect: are there any special enterprise programs or partnerships (for example, for medical device manufacturers or healthcare institutions) that allow an app to obtain additional background execution capabilities or enhanced HealthKit access beyond what is available to a standard Apple Developer Program member?

I understand that for a typical developer, continuous background execution is not permitted. However, I'm trying to determine whether there is any alternative path that would enable more persistent background health data monitoring for medical-grade applications.

If such programs exist, I'd appreciate any guidance on how to explore or apply for them.

Thank you for your time and insight.
