Your Apple Watch already keeps good records — here's how to bring them into PHR
Your Apple Watch quietly keeps good records — your heart rate through the day, how you slept, the occasional ECG. PHR can pull that history in so it lives alongside the rest of your health record, no retyping. The one thing to know up front is that the watch doesn't talk to PHR directly: its data flows into the Health app on your iPhone, and PHR reads it from a Health export file.
First, the one-time setup
Everything below starts the same way. On your iPhone, open the Health app and export your data — that hands you a file. Move it to your iPad with AirDrop or Files, and PHR reads what it needs straight out of it. PHR never connects to Apple Health; it just opens the file you give it.
Vitals — the everyday readings
Vitals are the measurements your watch takes all day: heart rate, resting heart rate, respiratory rate, blood oxygen, and the like. This import has been around a while, and it lives in the Settings import menu — open Settings, choose Import, and bring your vitals in from the Health file.
Sleep — new in 2.3.0
If you wear the watch overnight, it tracks your sleep. The Sleep import arrived in version 2.3.0, and unlike Vitals, it lives in the Home Monitoring section — open the Sleep screen there and import from it. It brings in your nightly sleep history so you can watch it add up over time.
ECG — also new in 2.3.0
Every ECG you record on the watch gets saved. That import also landed in 2.3.0, and like Sleep, it's in the Home Monitoring section rather than the Settings menu — open the ECG screen there and import. PHR brings in each recording along with what the watch noted for it.
Why some imports are in Settings and others aren't
Quick orientation so you're not hunting: the older Vitals import sits in the Settings import menu, while the two newer ones — Sleep and ECG — live over in the Home Monitoring section, with the import button right on each screen. If you're after Sleep or ECG, open it under Home Monitoring and import from there, not from Settings.
