Heart Rate Alerts: Setup and FAQ

Heart Rate Alerts are part of Heart IQ, with a Cardiogram Premium subscription. When enabled, Cardiogram can notify you if your heart rate goes above or below thresholds you set, helping you stay more in tune with your health.

🔔 What are Heart Rate Alerts?

Cardiogram can send a push notification to your phone and/or wearable when your heart rate rises above or drops below your chosen limits.

To prevent false alarms, Cardiogram will only send an alert if:

• It receives at least two consecutive readings above or below the threshold
• The data is less than 3 hours old

⚠️ If you’re using Fitbit or Garmin, Cardiogram receives data only when the device syncs with the Fitbit or Garmin app.

✅ How to enable Heart Rate Alerts

1. Open the Cardiogram app
2. Tap the ☰ menu (top-left of the Timeline screen)
3. Tap Settings > General
4. Scroll to Heart Rate Alerts and set your desired min and max values
5. Toggle the alerts ON

📌 Cardiogram alerts are push notifications. Be sure notifications are enabled on your phone:

iPhone:

• Go to your iPhone's Settings > Cardiogram > Notifications
• Turn on Allow Notifications

Android:

• Go to your phone’s Settings > Apps > Cardiogram > Notifications
• Turn on Show Notifications

🔁 If you reinstall the app or switch phones

You’ll need to re-enable notifications and toggle alerts back on after reinstalling Cardiogram or using a new phone.

🕒 Why heart rate notifications might be delayed

Heart rate alerts depend on when your wearable syncs new data:

1. Your watch collects heart rate in the background
2. It syncs data to your phone when connected (not constantly, to conserve battery)
3. Once data reaches your watch app (Apple Health, Fitbit, Garmin Connect, etc.), Cardiogram imports it
4. Cardiogram analyzes the data
5. If the heart rate crosses your threshold, Cardiogram sends an alert to your phone and wearable

🔁 This process can introduce some delay, especially on wearables that sync less frequently.

❌ Not receiving heart rate alerts?

Here’s what to check:

• Notifications disabled?

  • Re-enable them in your phone’s Settings → See steps in Enabling Heart Rate Alerts above

    Not enough data?

  • Alerts only trigger if Cardiogram receives at least two recent readings outside your threshold

    Your wearable hasn’t synced recently?

  • Cardiogram only alerts based on data that is less than 3 hours old
  • If you're using Fitbit or Garmin, open their companion app regularly to keep Cardiogram up to date
