Heart Rate Alerts: Setup and FAQ

What are heart rate alerts?

Within Cardiogram, you can configure the app to send a push notification to your phone and wearable when your heart rate goes above or below a certain threshold.

Heart rate notifications will only be sent if the data sent to Cardiogram is recent (within the last 3 hours). If you have a Fitbit or Garmin watch, Cardiogram will only receive the data after your watch is synced with the Fitbit or Garmin apps. Please see this article for more information on collecting heart rate readings more frequently. 

To avoid sending notifications when your watch is lying on the table or collecting readings infrequently, a notification will only be sent if Cardiogram receives at least two consecutive heart rate readings above or below the threshold you set.

If you do not receive any notifications, please see the I'm not receiving any notifications section below.

Enabling heart rate alerts

  • From the timeline page in Cardiogram, tap on the menu in the upper left-hand corner.
  • Under "Settings," select "General."
  • Under the "Heart Rate Alert"
  • Ensure your phone's settings are set to allow Cardiogram to deliver notifications from the app. You may see a message advising that your notifications are turned off. Tap on the blue text "turn them on in Settings" and enable in-app notifications.

If the link doesn't work, you can verify push notifications are turned on for Cardiogram in your phone settings.

  • Open the "Settings" app on your phone.
  • Scroll down to find "Cardiogram" in the app list.
  • Within the "Cardiogram" setting, tap "Notifications."
  • Ensure 'Allow Notifications' (Apple) / 'Show Notifications' (Android) is turned on.

Once you've enabled Cardiogram's in-app notifications, jump back over to Cardigoram's settings.

  • Set a minimum and a maximum heart rate of which you want to be notified.
  • Toggle the alerts on.

Once you enable push notifications for Cardiograms and turn on your alerts within the Cardiogram app, you should start receiving heart rate alerts.

If you re-install Cardiogram or change to a new phone, you may need to re-enable push notifications.

My heart rate notifications are delayed.

Depending on your wearable, there may be a delay between when the measurement was taken to when your watch connected to your phone to sync new data. Watches are not constantly connected or sending new data to our phones every second by design to allow users to have the most battery life throughout the day.

Your watch will take a measurement automatically, then periodically connect to your phone and sync any new data. Once the data is synced with your phone's watch app, it is imported to your Cardiogram profile.

Once Cardiogram receives the new data, it is processed for any measurements above or below the threshold, triggering an alert that is pushed from the app to your phone and wearable.

This process can cause a delay.

I'm not receiving any heart rate notifications

You may not be receiving any notifications for the following reasons:

If you have reinstalled the app or changed your phone: please re-enable push notifications (see: Enabling heart rate alerts section above).

Not enough heart rate readings to trigger an alert: Please see this article for more informationHow do I make Cardiogram collect data more frequently?

Heart rate data is not synced to Cardiogram frequently. We only alert you if the heart rate data is at most 3 hours old. However, we only receive heart rate data from Fitbit and Garmin if your wearable syncs with the Fitbit or Garmin apps. So if you don't sync your Fitbit or Garmin wearable for over 3 hours, then alerts won't be sent for any heart rate data that is older than 3 hours.
