FAQ
Questions, answered.
What is HealthAPI?
HealthAPI is an iPhone app and web service from Overarch.ai LLC. It syncs the Apple Health data you choose to your own private account. Claude, ChatGPT and other AI apps read it through a read-only connector (an MCP server) that you approve on your iPhone, and your own code can read it over a REST API with your key.
How is it different from ChatGPT Health and Claude's Apple Health option?
Those are built into one assistant each, and both are US only: Health in ChatGPT connects from the ChatGPT iPhone app, and Claude's option is a beta for Pro and Max in the Claude iPhone app. HealthAPI isn't limited to the US, works on every Claude plan including Free, on the web and desktop as well as your phone, and one sync serves Claude, ChatGPT and your own code. Every option, compared.
Which AI apps work with it?
Claude, from its connector directory, on every plan (steps). ChatGPT, as a plugin on Plus, Pro, Business, Enterprise or Edu (steps). Mistral Vibe, Cursor, Claude Code and other MCP clients too, and anything that can call a REST API.
Does it work outside the US?
Yes. HealthAPI is on the App Store in every country we checked, and connecting it doesn't depend on where you live. People use it from the UK, Europe, Canada, Australia, India and Japan (how).
Can an AI app change or delete my health data?
No. Every connection is read only and approved on your iPhone. Data goes to an AI app only when you ask it something, and you can disconnect any app in HealthAPI under Settings, Connected apps.
What does it cost?
Free for 2 days, no card needed. Then an optional 7-day free trial when you subscribe. After that, Pro is $4.99 a month or $49.99 a year for 100 requests a day, and Developer is $9.99 a month or $99.99 a year for 1,000 a day. You buy and manage plans in the iPhone app.
