Sync Apple Health to your own Supabase/Postgres, then query it live from Claude, Claude Code, Cursor, ChatGPT, or Ollama via a local MCP server. Continuous HealthKit sync — not a one-shot export.

Your HRV trended well this week — Wednesday was a standout at 71ms, your highest in 3 weeks. Here's the full picture:
avg: 65ms · range: 58–71ms · 7-day trend: ↑
Sleep was consistent (7h 10m avg). Active energy slightly below your baseline on Tuesday — rest day effect.
health4.ai syncs Apple Health into a Supabase Postgres project you create and own. Run the schema, deploy one Edge Function, sign in from the iOS app — then point a local MCP server at that database for Claude and Cursor. No subscriptions, no health4.ai server, no lock-in.

Tap to authorize HealthKit. Background sync starts immediately — HKObserverQuery + BGProcessingTask push every new sample as it arrives, without opening the app.
Create a Supabase project you own, run the schema, deploy the ingest function. Your decade of health history lands on day one.
Add the Apple Health MCP server to Claude Desktop, Claude Code, or Cursor. Then ask: "How's my sleep debt this week?" "When was my HRV last above 70?" "Am I ready to train tomorrow?"
Claude's native Apple Health connector only works on claude.ai web. health4.ai also works with Claude Code, the Claude API, ChatGPT, Cursor, and any tool that supports MCP.
The iOS app backfills your full Apple Health archive on first sync — every step, heartbeat, and workout going back to when you first wore a wearable.
HKObserverQuery fires the moment Apple Health gets a new sample. Your AI always has fresh data without you doing anything.
Your health data syncs to a Supabase project you control. We don't store a copy, sell it, or have access to it. GDPR-friendly by construction.
