What goes on the page
| Section | Where it comes from | What the AI shows |
|---|---|---|
| Resting heart rate | Apple Watch | 3-month average, monthly averages, lowest and highest day |
| Blood pressure | A cuff whose app writes to Apple Health, or readings you add | Average systolic and diastolic, days measured, the day with the highest systolic |
| Weight | A smart scale, or weigh-ins you add | First and last weekly average, and the change |
| Sleep | Apple Watch or a sleep app | Average time asleep, and how many short nights |
| Steps | iPhone and Apple Watch | Daily average for each month |
| Blood glucose | A CGM or meter app that writes to Apple Health | Monthly average, lowest and highest day |
A section with no data is left out, and you can drop any section you'd rather keep to yourself. The AI reads only what you have synced; see the 50 synced metrics. For glucose and weight in more depth, see the glucose guide and the smart scale guide.
Make it in 5 steps
Install HealthAPI and let it sync
Get it from the App Store and allow Apple Health. It imports a year of history by default, so the last 3 months are there once the first sync finishes.Paste the prompt
Copy the prompt below into a new chat. Fill in what to leave out, or delete that line.Check the numbers
Ask “Show resting heart rate and weight week by week” and compare a few weeks with the Health app.Print it or save a PDF
See the next section. Bring it on paper, or attach it yourself in your patient portal.
The prompt
Make a one-page summary of my Apple Health data for a doctor's appointment.
Period: the last 90 days, ending yesterday.
Units: [lb or kg] for weight, [mg/dL or mmol/L] for glucose.
Include, if there is data:
- Resting heart rate: average, lowest and highest day, and the monthly averages
- Blood pressure: average systolic and diastolic, how many days had a reading, and the day with the highest systolic reading, with that day's diastolic
- Weight: first and last weekly average, and the change
- Sleep: average time asleep per night, and how often it was under 6 hours
- Steps: daily average per month
- Blood glucose: average per month, with the lowest and highest day
Leave out: [anything you don't want on the page]
Rules:
- One table per section, plain language, no advice and no diagnosis.
- Say which sections had no data, and how many days or readings each figure uses.
- Title it "Self-tracked data from Apple Health" with the date range.“Make a one-page summary of my last 3 months for my doctor.”
Here it is. Resting heart rate averaged 61 bpm (57 to 66). Blood pressure averaged 124/79 on 38 days with a reading. Weight went from 182 to 178 lb, and you slept 6.9 h a night.
Follow-ups that make the page more useful:
- “Add a line on when my resting heart rate was highest, and whether I had more workouts or less sleep that week.”
- “List every blood pressure reading from the last 30 days with its date and time, as a second page.”
- “Make it shorter: one table, one line per measurement.”
- “Write three questions I could ask my doctor about these numbers.”
Print it or save it as a PDF
- Claude: ask it to “put this in a doc”, then use Export to save a PDF or Word file. Claude's docs need Cloud code execution and file creation turned on in Settings, Capabilities.
- ChatGPT or any AI app: tap the copy button under the answer, paste it into Notes, Pages, Word or Google Docs, then print it or export a PDF from there.
- Read it before you share it. Delete anything you don't want your doctor to see. The page is yours to edit.
Patient portals like MyChart
HealthAPI can't send anything to MyChart, any other patient portal or your doctor. It only answers the AI apps and tools you connect, and AI connections are read only. If you want the summary in your portal, attach the PDF to a message yourself, if your portal allows attachments, or bring it on paper.
Apple's own sharing options
The Health app has its own ways to share. Each does a different job:
| Option | What it does | Where it works |
|---|---|---|
| Share with your doctor (Health, Sharing) | Sends topics you pick, such as activity, heart rate, blood pressure and sleep, to your doctor's records system. New data uploads about once a day. | US only, at health organizations that support it. iOS 15 or later. Stop anytime. |
| Health Records | Downloads your allergies, conditions, medications, labs and vaccinations from your providers into the Health app. | Not in all countries or regions, and your organization may not be listed. It brings records in; it doesn't send your data out. |
| Share with someone (Health, Sharing) | Shares topics you pick, and health notifications, with a family member or friend. | They need to be in your contacts. |
| Export All Health Data | Everything in Health as an XML file, a format meant for moving data between apps. | Anywhere, but it's raw records, not something to hand a doctor. |
| HealthAPI with an AI app | A readable one-page summary of the measurements you choose. | Wherever the AI app works. You print it or attach it yourself. |
If your health system offers Share with your doctor, use it: your doctor sees the data in their own system. A printed page helps when they don't, or when you want to choose exactly what's on it.
Questions
Can HealthAPI send my data to MyChart or my doctor?
No. HealthAPI can't send anything to MyChart, any other patient portal or your doctor. It only answers the AI apps and tools you connect. You bring the page to your appointment, or attach the PDF yourself if your portal's messages accept attachments.
Can I share Apple Health data with my doctor without another app?
In the US, if your health system supports it, the Health app's Sharing tab can share chosen topics with your doctor, who sees them in their records system. Apple says new data uploads about once a day and you can stop at any time. Elsewhere, or when your doctor isn't set up for it, a printed summary works anywhere.
Does the summary include lab results or medications?
No. HealthAPI reads measurements such as heart rate, blood pressure, weight, sleep and steps. Health Records from your providers (labs, medications, allergies) stay in the Health app; HealthAPI doesn't read them.
Can I trust the numbers?
Check them. AI apps can make mistakes, so ask for the same figures week by week and compare a few with the Health app before you print. The page should also say how many readings each figure uses.
How many requests does it take?
About ten lookups for three months: one each for resting heart rate, both blood pressure numbers, weight, steps and glucose, one for all the nights of sleep, and a few more if you ask for single blood pressure readings. Syncing from your iPhone never counts.
Is this a medical record?
No. It is your own tracked data, summarized by an AI app. HealthAPI and the AI apps aren't medical devices and don't diagnose anything. Your doctor decides what the numbers mean.
