The Withings ScanWatch is a hybrid watch with classic hands and a small screen. It tracks your sleep, heart rate, and oxygen saturation. The same setup also works for other Withings wearables such as the Steel HR and ScanWatch Light, and for the Withings Sleep Mat. (Withings scales and blood pressure monitors sync to Health Mate too, but MigraineMe does not read weight or blood pressure at the moment.)
MigraineMe does not talk to Withings directly. There is no Withings sign-in inside MigraineMe. Instead, your Withings device sends data to your phone's main health app, and MigraineMe reads it from there.
- On iPhone: the bridge is Apple Health.
- On Android: the bridge is Health Connect.
The steps are different on each phone. Find yours below.
On iPhone
Step 1: Make sure Withings is sending data to Apple Health
- Open the Withings Health Mate app on your iPhone.
- Tap your profile picture at the top left.
- Tap Apps.
- Find Apple Health in the list.
- Tap Apple Health, then Connect.
- A permissions window from Apple Health appears.
- Tap Turn On All, then Allow.
If you have done this before, you may see "Disconnect" instead of "Connect". That means it is already connected.
Step 2: Connect Apple Health inside MigraineMe
- Open MigraineMe.
- Tap the gear icon in the top-left of the screen.
- Tap Connections.
- Find the Apple Health card at the top of the list.
- Tap the Connect button on the right.
A permissions panel from Apple will slide up.
- Tap Turn On All at the top.
- Tap Allow in the top right.
The button now reads Connected.
Step 3: Wait a few hours
The first time, it can take a few hours for past data to come through Withings, into Apple Health, and then into MigraineMe. After that, new data appears within minutes.
On Android
Step 1: Install Health Connect (if you do not have it)
Health Connect is Google's free bridge for sharing health data.
- Open the Play Store.
- Search for Health Connect.
- Tap Install.
- Open it once after it installs.
If your phone says "Health Connect is already installed", skip this step.
Step 2: Make sure Withings is sending data to Health Connect
- Open the Withings Health Mate app on your phone.
- Tap your profile picture at the top left.
- Tap Apps.
- Find Health Connect in the list.
- Tap Health Connect, then Connect.
- A Health Connect window appears listing categories. Tap Allow all.
Step 3: Connect Health Connect inside MigraineMe
- Open MigraineMe.
- Tap the gear icon in the top-left of the screen, then Connections.
- Find the Health Connect card.
- Tap the Connect button.
A Health Connect window appears.
- Tap Allow all.
- Tap Done.
The button now reads Connected.
Step 4: Wait a few hours
Past data takes a few hours the first time. New data appears within minutes after that.
Troubleshooting
"Connected but no Withings data"
The chain has three links: watch, Withings Health Mate, your phone's health app. If any one is broken, MigraineMe sees nothing.
- Open Withings Health Mate and check today's numbers are there.
- On iPhone, open the Health app and tap Browse, then Sleep (or Heart). You should see Withings as a source.
- On Android, open Health Connect, tap Data and access, then Sleep or Steps. You should see Withings Health Mate listed.
If a step fails, walk back through Step 1 above.
"Sleep is missing"
Sleep tracking needs your ScanWatch worn through the night. Pull the watch close to your phone in the morning and let it sync. The data takes an hour or two to process, then flows into Apple Health or Health Connect.
"Some metrics are missing"
Withings shares most metrics, but a few of its more advanced numbers (like atrial fibrillation alerts) stay inside Health Mate. MigraineMe reads the standard categories it tracks: sleep, heart rate, steps, body temperature, and oxygen saturation. It does not read weight or blood pressure at the moment.
