Connecting your heart data from Apple Health (iPhone)

Take a breath, this is short and only needs to be done once. MigraineMe does not talk to your watch directly. Instead, it reads from Apple Health, the little white app on your iPhone with a red heart. Your watch (Apple Watch, Oura, Garmin, Fitbit, and so on) already sends its data into Apple Health. MigraineMe just reads what is there.

Step 1: Open MigraineMe

1. Find the MigraineMe icon on your home screen.
2. Tap it.

Step 2: Go to Connections

1. Tap the gear icon in the top-left of the screen.
2. Tap Connections.
3. Find Apple Health in the list.
4. Tap the Connect button next to it.

Step 3: Give permission

A new screen will slide up. This screen comes from your iPhone, not from us. It shows a long list of things MigraineMe would like to read.

1. At the top, tap Turn On All.
2. If you would rather pick and choose, scroll the list and switch on at least:

• Heart Rate
• Resting Heart Rate
• Heart Rate Variability
• Oxygen Saturation (if your watch measures it)
• Respiratory Rate (if your watch measures it)
• Body Temperature (if your watch measures it)

1. Tap Allow in the top corner.

The screen will close on its own.

Step 4: Check that it worked

1. Tap the Monitor tab.
2. Scroll to the Physical Health card.
3. You should see your resting heart rate and your HRV.

If the card is empty, do not worry. New data sometimes takes an hour to appear, especially first thing in the morning.

What MigraineMe reads

MigraineMe is allowed to read these heart and body signals from Apple Health:

1. Heart rate (for heart-rate goals and workout heart rate)
2. Resting heart rate
3. Heart rate variability (HRV)
4. Oxygen saturation (SpO2)
5. Respiratory rate (your breaths per minute)
6. Body temperature
7. Blood glucose

It also reads your steps, workouts and active energy if your watch records those. MigraineMe does not read weight or blood pressure at the moment. You can switch any of these on or off at any time.

If something went wrong

The permission screen never appeared

1. Close MigraineMe by swiping it up off the screen.
2. Open it again.
3. Try Settings, Connections, Apple Health, Connect once more.

The button says Connected but the Physical Health card is empty

This usually means Apple Health does not have heart data yet.

1. Open the Health app (white icon, red heart).
2. Tap Browse.
3. Tap Heart.
4. If this is empty, your watch has not sent anything to Health yet. Open your watch's own app and pull down to refresh.

I want to change what MigraineMe can see

1. Open the Settings app on your iPhone (grey gear icon).
2. Tap Apps, then Health.
3. Tap Data Access & Devices.
4. Tap MigraineMe.
5. Switch things on or off as you like.

A gentle note

MigraineMe cannot see anything you have not given it permission to see. It writes back only two things: the attacks you log (as Headache) and the periods you log in MigraineMe (as Menstruation). It never writes heart data.
