Can’t see your Apple Watch data in Cardiogram? Here’s what to do
If you’re not seeing new heart rate data from your Apple Watch in the Cardiogram app, it’s usually a sync or permissions issue — and it can often be resolved in a few quick steps.
🔄 Step 1: Restart your devices
Start by restarting both your:
- iPhone
- Apple Watch
This often clears up temporary sync conflicts between your devices and the Health app.
📶 Step 2: Check connection and updates
Make sure the following are true:
- Bluetooth and Wi-Fi are enabled on both devices
- Your iPhone is running iOS 13 or newer
- Your Apple Watch is running watchOS 6.2 or newer
- You have the latest version of the Cardiogram app
❤️ Step 3: Confirm that your Apple Watch is syncing to Apple Health
Cardiogram does not pull data directly from your Apple Watch — instead, it imports your data from Apple Health (HealthKit) on your iPhone.
To check if your Apple Watch is syncing to Apple Health:
- Open the Health app on your iPhone
- Tap the Browse tab at the bottom
- Tap Heart
- Look for a heart rate summary for today
If you don’t see any heart rate data for today:
- Your Apple Watch may not be syncing correctly
- Follow Apple’s pairing and sync troubleshooting steps
🔐 Step 4: Check Cardiogram’s HealthKit permissions
If you do see heart rate data in the Health app but not in Cardiogram:
- Open your iPhone’s Settings
- Tap Privacy & Security
- Tap Health > Cardiogram
- Make sure all categories are turned on
🛠 If syncing still doesn’t work, try toggling all categories off, then turning them back on again — this resets permissions and often resolves import issues.
