## What is MetricBridge?

Your Apple Health data, answered on your iPhone and handed to the AI agent you already use.

MetricBridge does two things. It answers plain-language questions about your Apple Health data entirely on the device, and it exports 190 metrics as clean JSON to a destination you choose, so your own AI agent can read your real numbers.

ASK YOUR DATA
Type "how's my resting heart rate trending this week" and get an answer built from your own history.
• Every figure is computed by ordinary code inside the app, not guessed by a model
• The app shows the metric, the date range and how many days of data it used, so you can check the work
• Runs on your iPhone. The question, the data and the answer never leave the device
• An optional on-device model can phrase answers more naturally. It only restates numbers the app already computed, and can never state a figure the app did not compute
• Weekly Brief: a short recap of your week, written on device

IT KNOWS ITS LIMITS
Ask something clinical, like "should I stop taking my statin", and it declines, then offers to show you the data to bring to that conversation. It reports what you recorded. It does not interpret it.

190 METRICS AS CLEAN JSON
Activity, heart, HRV, mobility, respiratory, body, sleep, hearing and nutrition, plus workouts and Age. Written as structured JSON to a destination you pick:
• Your iCloud Drive (default)
• A folder on your device
• Your own local network over HTTP or WebSocket
• Any webhook URL you trust

Background auto-export refreshes the file when new health data arrives, so your agent's context does not go stale. Every delivery is token-authenticated, and the in-app history shows exactly what was sent, when, and whether it succeeded.

A READ-ONLY MCP SERVER
MetricBridge ships a zero-dependency, open-source MCP server that you install on your own computer. It gives any MCP client 14 read-only tools:

get_mcp_status · list_metrics · get_health_metrics · get_trends · compare_periods · get_structured_export · get_intraday · query_health_data · list_events · get_profile · get_workouts · get_sleep_sessions · get_cycle_context · correlate_metrics

Ask your assistant to compare your HRV this week against last week and it calls the tools, then answers from your real numbers. No dashboard to build, no files to wrangle. Works with Claude Desktop, Claude Code, Cursor, VS Code, opencode and any other MCP client. Your agent reads only after you pair it with a code from the app, and you can regenerate that code whenever you want.

PRIVATE BY DESIGN
• Read-only. The app reads Apple Health and never writes to it or changes it
• No account, no sign-in, and no ads inside the app. Your health data is never used for advertising
• No third-party AI service is involved, and no data reaches a server we operate
• Reproductive health, sexual activity and alcohol stay excluded unless you turn them on

PRICING
A 7-day free trial, then a single one-time purchase that unlocks everything permanently: export, Ask and the Weekly Brief. Not a subscription. Nothing renews and there is nothing to cancel.

MetricBridge is a tool, not a medical device. It does not diagnose, treat or provide medical advice.

## Version history (last 5 releases)

### 1.8 — 2026-09-05

Bug fixes. Delete All Exports now actually deletes every context file, not just some of them. Disconnecting a folder no longer reports success when the delete failed. The folder picker no longer points you at Google Drive by mistake.

### 1.7 — 2026-08-30

Fixed: the setup screen used to tell you to choose a Dropbox, Google Drive or OneDrive folder. iOS only lets apps pick folders in iCloud Drive or On My iPhone, so those appear greyed out — the screen now says that up front, and tells you what to do instead.

Removing a folder now takes the exported files back with it, and deleting exports tells you if it couldn't reach the folder instead of reporting success.

### 1.6 — 2026-08-28

Events, Agent Profile, Doctor Report and What Leaves This Phone are now fully translated in every supported language — these screens previously showed English text regardless of your device language.

### 1.5 — 2026-08-25

Health Export AI is now MetricBridge. Same app, same on-device privacy, bigger toolbox.

EVENTS TIMELINE: log a medication change, a quit date, a doctor visit or a shift block. Your AI can then compare before and after instead of averaging across the change, and every export carries the timeline.

DOCTOR REPORT (PDF): a selective, print-safe summary with trend charts, a since-your-last-visit comparison and honest coverage counts on every metric.

AGENT PROFILE: opt-in context (conditions, medications, goals, allergies) for your AI. Each field leaves the phone only while its switch is on.

WHAT LEAVES THIS PHONE: one screen listing exactly which files each destination receives and what is withheld.

WORKOUTS: per-interval structure, running dynamics (power, stride length, vertical oscillation, ground contact time) and GPX route export.

EXPORTS: sleep sessions with local time offsets, observed cycle context (opt-in), a timezone change log for travel honesty, and CGM daily metrics (time in range, CV, GMI) computed on device.

MCP SERVER 1.4.3: 14 read-only tools, 22 prompts, a demo mode and a doctor command.

One purchase now includes everything, including Ask on this device. No subscription.

### 1.4 — 2026-08-18

The hourly Vitals schedule can now deliver to iCloud or a folder too: it writes health-intraday.json alongside your daily export.
