# HealthKit Sync CLI

Securely sync Apple HealthKit data from iPhone to Mac over local network using mTLS.

## When to Use This Skill

- User asks about syncing health data from iPhone
- User mentions `healthsync` CLI commands
- User wants to fetch steps, heart rate, sleep, or workout data
- User needs to pair a Mac with an iOS device
- User asks about the iOS Health Sync project architecture
- User mentions certificate pinning or mTLS patterns

## CLI Quick Reference

### Pairing Flow (First Time)

```bash
# 1. Discover devices on local network
healthsync discover

# 2. On iOS app: tap "Share" to generate QR code, then "Copy"
# 3. Scan QR from clipboard (Universal Clipboard)
healthsync scan

# Alternative: scan from image file
healthsync scan --file ~/Desktop/qr.png
```

### Fetching Health Data

```bash
# Check connection status
healthsync status

# List enabled data types
healthsync types

# Fetch data as CSV (default)
healthsync fetch --start 2026-01-01T00:00:00Z --end 2026-12-31T23:59:59Z --types steps

# Fetch multiple types as JSON
healthsync fetch --start 2026-01-01T00:00:00Z --end 2026-12-31T23:59:59Z \
  --types steps,heartRate,sleepAnalysis --format json | jq

# Pipe to file
healthsync fetch --start 2026-01-01T00:00:00Z --end 2026-12-31T23:59:59Z \
  --types steps > steps.csv
```

### Available Health Data Types

**Activity**: steps, distanceWalkingRunning, distanceCycling, activeEnergyBurned, basalEnergyBurned, exerciseTime

The mTLS pairing is the point

Syncs Apple HealthKit data from an iPhone to a Mac over the local network with mutual TLS certificate pinning, Keychain storage and audit logging — steps, heart rate, sleep and workouts. The security model is the substance here: pinned certificates and a paired device beat an unauthenticated local endpoint. Config lives in ~/.healthsync/config.json. macOS plus the healthsync CLI required.

Use case: Pulling steps and sleep into a personal dashboard without a cloud health service

Pulling health data from a phone to a mac

Pair once and keep the configuration file, because every later fetch depends on that trust relationship.

Phone and mac must share a local network, so a vpn or a guest network can silently break discovery.

Check connection status before a large fetch, so a failed link is not mistaken for absent data.

Pairing is interactive and needs the phone app, so a fresh machine cannot be provisioned end to end from a script.

Steps, heart rate, sleep and workouts cover most trend questions without a full export.

This skill documents a command line tool that moves apple health data from an iphone to a mac over the local network, together with the pairing flow that makes that connection trustworthy. ## What it does - Discovers devices that are reachable on the local network. - Pairs with an ios device by scanning the code the phone app produces, either from the clipboard or from an image file. - Fetches health records including steps, heart rate, sleep and workouts. - Reports connection status before a fetch begins. - Uses mutual transport security, keychain storage and audit logging in the underlying project. ## When it is the wrong choice It needs a mac with the command line tool installed and a paired phone on the same network, so a headless server or a worker away from the device cannot use it. The pairing step is interactive and involves producing and scanning a code, which makes first time setup unsuitable for a fully unattended deployment. For historical questions that do not need fresh readings, an export taken from the phone is simpler and cheaper. Readings also arrive only when a sync runs, so the data is as current as the last successful exchange. ```bash healthsync discover healthsync scan healthsync status ``` ## Working notes - Pairing writes a configuration file under the user home, alongside other tool config. - Certificates are pinned rather than trusted from a general store, which is what makes the local link safe.
