Apple HealthKitV2 Activity Summaries Export Format

HealthKitV2 activity summaries are generated by the Apple Watch and are the data behind the activity rings used to encourage Apple Watch users to stand, exercise, and move around.

Activity Summaries are captured on a daily basis—each activity summary covers a single day.

Data Fields

Field Description
HealthKitActivitySummaryKey A unique, auto-generated key for the activity summary.
ParticipantIdentifier The identifier of the participant the activity summary is for. Can be used to cross reference with Participants.
ParticipantID The stable, automatically generated, internal system identifier for this participant. Universally unique identifier (UUID).
StartDate The start date of the activity summary, in ISO 8601 format. Includes timezone offset information. May be empty if no start date was recorded.
EndDate The end date of the activity summary, in ISO 8601 format. Includes timezone offset information.
ActiveEnergyBurned The active energy burned recorded by the Apple Watch, in kcal.
ActiveEnergyBurnedGoal The goal for ActiveEnergyBurned the participant set for themselves.
AppleExerciseTime The total exercise time recorded by the Apple Watch, in minutes.
AppleExerciseTimeGoal The goal for AppleExerciseTime the participant set for themselves.
AppleStandHours The number of hours in the day during which the participant stood up for at least 1 minute.
AppleStandHoursGoal The goal for AppleStandHours the participant set for themselves.
InsertedDate The creation date of the entry, in ISO 8601 format. Is always in UTC.

If a participant re-syncs their device, you may observe duplicate samples. HealthKit samples are immutable, so when doing data analysis, your team will need to remove any samples that have the same HealthKitActivitySummaryKey and ParticipantIdentifier as another sample.
