# HKActivitySummary

An object that contains the move, exercise, and stand data for a given day.

```
class HKActivitySummary
```

## Overview

You can read [`HKActivitySummary`](/documentation/HealthKit/HKActivitySummary) objects from the HealthKit store using an [`HKActivitySummaryQuery`](/documentation/HealthKit/HKActivitySummaryQuery) object. Unlike the [`HKSample`](/documentation/HealthKit/HKSample) subclasses,  [`HKActivitySummary`](/documentation/HealthKit/HKActivitySummary) instances are mutable, but changes made to the object’s properties have no affect on the values in the HealthKit store.

You can instantiate your own [`HKActivitySummary`](/documentation/HealthKit/HKActivitySummary) objects (if needed), but you can’t save [`HKActivitySummary`](/documentation/HealthKit/HKActivitySummary) objects to the store.

You can display an active summary in iOS using the [`HKActivityRingView`](/documentation/HealthKitUI/HKActivityRingView) class or in watchOS using the <doc://com.apple.documentation/documentation/WatchKit/WKInterfaceActivityRing> class.
