A Polar watch or heart rate strap tracks your sleep, heart rate, recovery, and training load. MigraineMe can read all of that and use it to spot migraine patterns.
Polar connects directly to MigraineMe. There is no Apple Health or Health Connect bridge in between. You sign in to your Polar Flow account once, and the data starts flowing. This works the same on iPhone and on Android.
On iPhone
Step 1: Make sure your device is syncing with Polar Flow
- Open the Polar Flow app on your iPhone.
- Look at today's screen. Do you see your steps and sleep?
- If not, charge your device, bring it near your phone, and open Polar Flow to sync.
If Polar Flow shows your data, you are ready.
Step 2: Connect Polar inside MigraineMe
- Open MigraineMe.
- Tap the gear icon in the top-left of the screen.
- Tap Connections.
- Find the Polar card in the list.
- Tap the Connect button on the right side of the card.
Your iPhone may ask if MigraineMe can use polar.com to sign in. Tap Continue. A Polar sign-in window then appears.
- Type your Polar Flow email and password.
- Tap Sign in.
- Tap Accept on the permissions screen.
The window closes on its own. The button on the Polar card will now read Connected.
Step 3: Wait a few minutes
The first time you connect, MigraineMe fetches up to 28 days of past Polar data. This can take a few minutes. After that, new data appears in MigraineMe within minutes of your watch syncing.
To check it is working, open the Monitor tab and look at the sleep and heart rate cards.
On Android
Step 1: Make sure your device is syncing with Polar Flow
Same as on iPhone. Open Polar Flow and check today's data.
Step 2: Connect Polar inside MigraineMe
- Open MigraineMe.
- Tap the gear icon in the top-left of the screen.
- Tap Connections.
- Find the Polar card.
- Tap Connect.
A browser window will open the Polar sign-in.
- Sign in with your Polar Flow email and password.
- Tap Accept.
The browser will send you back to MigraineMe. The button now reads Connected.
Step 3: Wait a few minutes
Same as on iPhone. Give it a few minutes for past data to flow in.
A note about past data
When you connect, MigraineMe fetches about the last four weeks (28 days) of your Polar data, then keeps up with new data from then on. Older history stays in Polar Flow. Make sure your device has synced with Polar Flow before you tap Connect, so the last four weeks are complete.
Troubleshooting
"Connected but no data"
- Open Polar Flow and pull down to refresh.
- Open MigraineMe and go to Monitor. On iPhone, pull down to refresh. On Android, switch to another tab and back to Monitor.
- Wait a few minutes.
If still missing, disconnect and reconnect: on iPhone tap the Connected button on the Polar card, on Android press and hold the Polar card. Tap Disconnect, then Connect again and sign in.
"I don't remember my Polar password"
Use the Forgot password? link on the sign-in screen to reset it. Once you can sign in to Polar Flow, come back to MigraineMe and try Connect again.
"I want to disconnect"
On iPhone, tap the Connected button on the Polar card. On Android, press and hold the Polar card. A "Disconnect Polar?" window will appear. Tap Disconnect.
"Some metrics are missing"
Polar shares most metrics, but it does not share a stress score the way Garmin does. MigraineMe works out a stress estimate for you from your heart rate variability and resting heart rate.
Still stuck?
Write to help@migraineme.app with your Polar device model and a screenshot of the Connections screen. We usually reply within a day.
