SensorKit

Collect research-grade sensor data from iOS and watchOS devices for approved research studies. SensorKit provides access to ambient light, motion, device usage, keyboard metrics, visits, phone/messaging usage, speech metrics, face metrics, wrist temperature, heart rate, ECG, and PPG data. Targets Swift 6.3 / iOS 26+.

SensorKit is restricted to Apple-approved research studies. Apps must submit a research proposal to Apple and receive the com.apple.developer.sensorkit.reader.allow entitlement before any sensor data is accessible. This is not a general-purpose sensor API -- use CoreMotion for ordinary accelerometer, gyroscope, pedometer, or activity-recognition features, and HealthKit for health records and workouts.
