# SensorKit

Retrieve data and derived metrics from sensors on an iPhone, or paired Apple Watch.

## Overview

Overview As the system gathers information using various sensors on a device, SensorKit enables an app to access select raw data, or metrics that the system processes from a sensor, such as: Steps information Accelerometer or rotation-rate data The configuration of a watch on the user’s wrist Ambient light in the physical environment Details about a user’s routine commute or travel See SRSensor for the complete list. note: This framework ignores calls from Mac apps that you build with Mac Catalyst, and from compatible iPad and iPhone apps running in visionOS.
