What the publisher says

From the health4ai repository's README, as published. We do not edit it. Read it on GitHub

health4.ai — Apple Health × AI

Ask your AI about your sleep, HRV, recovery, and fitness — in plain language. Free iOS app · Your own database · Works with any MCP client

What it does

iPhone HealthKit → Your Supabase project → MCP server → Any AI

Apple Health holds years of your biometric data — sleep stages, HRV, heart rate, workouts, VO₂ max, and 150+ other metrics. health4.ai makes all of it queryable from Claude, ChatGPT, Cursor, Ollama, or any MCP-compatible client through purpose-built MCP tools.

You control the data. It syncs to a Supabase project you create and own. health4.ai runs no backend and never stores or has access to your health data.

Why it exists

Demo

Demo video coming. Here's what a typical conversation looks like:

You:     How was my recovery this week? Anything standing out?

Claude:  Your recovery this week was mixed but trending positive.
         • HRV averaged 58ms (Tue–Thu strong at 64–68ms; Monday low at 44ms after Saturday's long run)
         • Sleep averaged 7h 12m — Wednesday and Thursday were your best nights (7h 40m+)
         • Resting HR dropped from 54bpm Monday to 49bpm Friday — a good sign
         Recommendation: today looks like a solid day for a moderate-intensity session.

Quick start

health4ai needs a Supabase project you own. The app signs in with Supabase Auth and writes through a Supabase Edge Function, so plain Postgres (Neon, a local Docker container) is not a supported backend. Full walkthrough: docs/SETUP.md.

1. Create the schema. Create a project at supabase.com, open its SQL editor, and run web/public/schema.sql (also at https://health4.ai/schema.sql). It is generated from supabase/bootstrap/: tables, row-level security, and grants that deny clients direct access. Do not use supabase db push — the numbered migrations do not apply to a fresh project.

2. Deploy the ingest function (needs the Supabase CLI):

git clone https://github.com/jefflitt1/health4ai.git
cd health4ai
supabase functions deploy healthkit-ingest --project-ref <your-project-ref> --no-verify-jwt

--no-verify-jwt is deliberate: the function verifies the signed-in user's token itself and writes only under that user's ID.

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.
