Apple Health Export

Dataset Summary

A structured health and activity dataset derived from real Apple Health exports voluntarily shared by users. It covers raw sensor measurements from iPhone and Apple Watch devices.

The sample includes:

• 10 unique users
• 10,000 health records (1,000 per user) across multiple metric types
• Devices: iPhone and Apple Watch across multiple generations

Use Cases

• Activity analytics: step count trends, distance, flights climbed, exercise and move ring progress
• Sleep research: sleep stage classification (Core, Deep, REM, Awake, In Bed) over time
• Cardiovascular monitoring: heart rate patterns correlated with activity and time of day
• Gait analysis: walking speed, step length, double support percentage, asymmetry, and steadiness
• Energy modelling: basal vs. active calorie burn estimation across devices and users
• Audio exposure research: headphone loudness monitoring over sessions

Data Collection

Health data was exported directly from personal Apple Health accounts by participating users who consented to share their data. Each export is a standard export.xml file generated by the Apple Health app on iPhone.

Anonymization

• User IDs — original UUIDs hashed with SHA-256 (truncated to 12 hex characters), preserving cross-record linkability
• Source names — device/app names replaced with opaque sequential identifiers (source_1, source_2, …)
• Devices — only manufacturer and model identifier retained (e.g. Apple Inc. iPhone16,2); all other device metadata removed

Dataset Structure

The dataset contains one CSV file.

data.csv

Each row is a single health measurement recorded by an iPhone or Apple Watch.

Data Fields

Column	Type	Description
user_id	string	User identifier. Consistent across all records from the same user.
type	string	Metric name (see Record Types below), stripped of the HKQuantityTypeIdentifier / HKCategoryTypeIdentifier prefix.
value	string	The measured value. Numeric for most types (e.g. 72, 5.21, 245.11). Categorical string for sleep and stand-hour types (e.g. HKCategoryValueSleepAnalysisAsleepDeep).
unit	string	Unit of value. Empty for categorical records. Common values: count, km, mi, kcal, Cal, kJ, %, count/min, min, cm, in, km/hr, mi/hr, dBASPL, kcal/hr·kg.
startDate	datetime	Start of the measurement interval (YYYY-MM-DD HH:MM:SS +0000). For instantaneous measurements (e.g. heart rate) equals endDate.
endDate	datetime	End of the measurement interval. Varies by type — from under a second (heart rate) to hours (basal energy) to months (walking steadiness).
creationDate	datetime	Timestamp when the device persisted the record to HealthKit. Usually equal to or slightly after endDate.
sourceName	string	Source identifier for the app or device that recorded the data. Consistent within the dataset.
sourceVersion	string	OS or app version at the time of recording (e.g. 18.3.1).
device	string	Hardware that captured the measurement — manufacturer and model identifier (e.g. Apple Inc. iPhone16,2, Apple Inc. Watch6,6). Empty for third-party app sources.

All dates are in YYYY-MM-DD HH:MM:SS +0000 format.

Data Splits

Single split containing all records. No train/test separation — this is a raw data export, not a benchmark.
