Use Apple Health to review training and blood pressure

They linked ChatGPT to Apple Health to study exercise data and blood-pressure trends together.

What they did
They attached ChatGPT to Apple Health and relied on the synced records for run breakdowns, workout review, broader health planning, and blood-pressure tracking. They wanted the agent to line up blood-pressure changes with when they took medication, but the app could only see the medication list, not the dated log of doses. They then considered having Codex build a companion tool to surface those entries.
How it went
The setup works for the Apple Health categories ChatGPT can access, so it can summarize runs, workouts, and blood-pressure data. The limitation is that medication history is still hidden, so the agent cannot match readings to actual dose times yet.
Tips
Before depending on the analysis, check which Health categories your agent can actually see. If medication timing matters, confirm that your setup exposes dose logs rather than just the medication list.

Try it yourself with ChatGPT

Look through my connected Apple Health data for the last [time period]. Break down my [runs/workouts] by pace, heart rate, and weekly total, then review my blood-pressure readings for the same span and call out any patterns I should bring to my doctor. Also note any related data you could not access. Stop and ask me to confirm before you make or send anything that would change records, submit information, or trigger a payment.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
