Connect Apple Health to Claude
Add HealthSync as a custom connector in Claude and ask about your Apple Watch workouts, down to the heartbeat. A few clicks, no export.
What you need
- Any Claude plan, Free included. Free allows one custom connector; Pro and Max have no cap. On Team and Enterprise, an Owner adds it first from Organization settings.
- The HealthSync app on your iPhone, signed in with Apple, with at least one workout synced.
Step by step
Open Connectors
In Claude, open Settings. Under Customize, choose Connectors, then the Add button, top right.

Name it and paste the address
Name: HealthSync. Address: https://api.gethealthsync.ai/mcp. Choose Continue.

Keep what Claude detected
Claude reads the server and pre-selects Sign in now for authentication and Use Claude's published identity for the OAuth client. Both are right; leave the request headers empty and add the connector.

Connect
The connector's page says you are not connected yet. Choose Connect.

Approve from your iPhone
A HealthSync page opens with a QR code and a short code, valid for five minutes. It lists what will be shared: your workouts, read-only. Scan the code with your iPhone camera, or open HealthSync, go to Settings, then Connect an assistant, and type the code.

Allow access
The app shows what Claude will be able to see, and that it cannot change anything in Apple Health. Tap Allow access. Back in Claude, the connection is live.

Ask
Start a new chat and ask whether you are getting faster. Claude calls list_workouts on its own.
Your first question
Is my easy pace getting faster at the same heart rate since August?
healthsync · list_workouts running · 2026-08-01 → 2026-09-15 · 22 workouts
A little. Over 17 runs of 4 km or more, intervals aside, you cover 1.22 m per heartbeat in September against 1.19 in August: 2 % more, which is 8 seconds per kilometre at 130 bpm, 6:18 instead of 6:26. The standout is the 10th: 8.1 km with 181 m of climbing at 6:14/km and 127 bpm, your most efficient run of the two months. Seven September runs is a short sample; ask again in October.
Questions about Claude
Does this work in Claude Desktop and Claude Code too?
Yes. A connector added on claude.ai is available in Claude Desktop and loads automatically in Claude Code under the same account, with the same approval.
Claude cannot see this morning's run. Why?
The app syncs when it opens and in the background when iOS lets it. Open HealthSync once and ask again.
How do I cut Claude off?
In the HealthSync app, revoke the connection. The token is gone on the server, and Claude gets a 401 on its next call.
