AI Health Chat: Ask Questions About Your Apple Health Data
Your iPhone collects thousands of health data points every day. An AI health chat app lets you ask questions about that data in plain English and get personalized insights in seconds.
What is an AI health chat app?
An AI health chat app connects your Apple Health data to an AI model so you can have a conversation about your own health metrics. Instead of scrolling through charts and trying to spot patterns yourself, you ask the AI a question and it analyzes your actual data to give you an answer.
Think of it as having a personal data analyst who has read every heart rate reading, every sleep session, and every workout you have ever logged — and can answer any question about it instantly.
Natural Language
Ask questions in plain English — no data science needed
Personalized Insights
Answers based on your real health data, not generic advice
Instant Analysis
Trends, correlations, and patterns found in seconds
Why use AI to analyze your health data?
Apple Health is great at collecting data. Your Apple Watch alone records heart rate, HRV, blood oxygen, step count, sleep stages, and more — all day, every day. The problem is that Apple Health only shows you basic charts and daily summaries. It does not tell you what the data means for you.
AI changes that. When you give an AI model access to your health data, it can find patterns across weeks and months, spot correlations between different metrics, and answer specific questions that the Health app simply cannot.
Questions you can ask an AI health chat
- --"How has my resting heart rate trended over the last 6 months?"
- --"Do I sleep better on days when I exercise?"
- --"What is my average HRV and is it improving over time?"
- --"Which days of the week am I most active based on step count?"
- --"Summarize my overall health trends and flag anything unusual"
How AI Health Export turns your iPhone into an AI health chat
AI Health Export is an iPhone app that bridges the gap between Apple Health and AI. It syncs your health data from HealthKit, formats it for AI analysis, and lets you query it using the AI model of your choice — all without your data ever leaving your device by default.
Sync your Apple Health data
AI Health Export reads directly from Apple HealthKit on your iPhone. There is no need to manually export an XML file or transfer anything to a computer. You select the metrics you care about — sleep, heart rate, HRV, VO2 max, steps, workouts, and more — and the app pulls your data instantly.
Ask questions with AI
Once your data is loaded, you can chat with an AI about it. Ask questions in plain English and get answers grounded in your actual health readings. The app includes ready-to-use prompts for common analyses like sleep quality, fitness trends, and heart health — or you can ask anything you want.
Get insights — your data stays private
The AI analyzes your data and returns clear, actionable insights. By default, everything is processed on your device using on-device AI. If you prefer, you can also export your data as a CSV and use it with ChatGPT, Claude, Gemini, or any other AI tool. Either way, you are in full control of where your data goes.
87 health metrics you can ask AI about
AI Health Export supports 87 metrics across every category that Apple Health tracks. This is not a limited subset — it covers virtually everything your Apple Watch, connected devices, and apps record.
Heart & Vitals
Heart rate, resting heart rate, heart rate variability (HRV), VO2 max, blood pressure (systolic and diastolic), blood oxygen saturation, respiratory rate, body temperature, and ECG results
Activity & Fitness
Steps, distance walked and run, flights climbed, active energy burned, basal energy, exercise minutes, stand hours, cycling distance, swimming distance, running power, and all workout types
Sleep
Total sleep duration, time in bed, core sleep, deep sleep, REM sleep, sleep latency, and sleep stage timestamps — everything you need for detailed AI sleep analysis
Body & Nutrition
Weight, BMI, body fat percentage, lean body mass, water intake, caffeine, protein, carbohydrates, fats, calories, vitamins, minerals, blood glucose, and insulin delivery
On-device AI vs. cloud AI: you choose
AI Health Export gives you two ways to chat with AI about your health data. Each approach has different strengths, and you can use both depending on what you need.
On-Device AI
The AI runs directly on your iPhone. Your health data never leaves your device — not even to a cloud server. This is the most private option and works without an internet connection.
- Data stays 100% on your iPhone
- Works offline — no internet needed
- Maximum privacy for sensitive health data
Cloud AI (ChatGPT, Claude, Gemini)
Export your data as CSV and upload it to any cloud AI tool. Cloud models are more powerful for complex analysis, multi-step reasoning, and generating detailed reports or visualizations.
- More powerful AI models for deeper analysis
- Can generate charts, graphs, and reports
- You choose exactly which data to share
Privacy-first by design
Health data is some of the most personal information you have. AI Health Export was built from the ground up to keep it under your control.
Your data never leaves your iPhone by default
- --No servers, no cloud storage, no accounts required. AI Health Export does not have a backend. There is nowhere for your data to be sent.
- --On-device AI processing means the entire analysis happens locally on your iPhone. Your health data is never transmitted over the internet.
- --If you choose to export a CSV and upload it to a cloud AI, that is your explicit decision. The app never does this automatically.
- --Face ID protection ensures only you can access and export your health data from the app.
Who uses an AI health chat app?
People tracking fitness goals
Ask AI to analyze your workout patterns, recovery metrics, and VO2 max trends. Find out which training routines give you the best results and where you might be overtraining or underrecovering.
Anyone trying to improve sleep
AI can analyze your sleep stages, identify patterns in when you get the most deep and REM sleep, and correlate sleep quality with daytime activity, caffeine intake, or exercise timing.
Health-conscious individuals monitoring vitals
Track long-term trends in heart rate, HRV, blood pressure, and blood oxygen. AI can flag when a metric is trending in an unexpected direction and help you understand what might be causing the change.
People preparing for doctor visits
Generate a summary of your health trends to bring to your next appointment. AI can organize months of data into a clear overview that helps your doctor see the full picture, not just a snapshot.
