# com.apple.developer.healthkit.research

A Boolean value that indicates whether an approved health research app offers only Full Access when it requests HealthKit read access.

## Discussion

In iOS 27 and later, HealthKit allows people to choose between two options when they share data with an app: **Past 30 Days and Future Data** and **All Recorded Data and Future Data**. Apps with this entitlement offer only Full Access for people to approve or deny, without the **Past 30 Days and Future Data** option. HealthKit periodically reminds people that an app can read their health data, but reminds them about apps with this entitlement less often.

Use this entitlement if your app is a health research app that needs uninterrupted access to HealthKit data. For example, apps that collect data from infrequent health events can’t tolerate a gap in access. Apple grants this entitlement individually to qualifying apps. To request permission to use it, see [HealthKit Research Entitlement Request](https://developer.apple.com/contact/request/healthkit-research-entitlement).
