Yes, you can now set heart rate alerts on your Fitbit for high and low heart rates, just like the Apple Watch! Plus, you can even customize and edit the threshold ranges for your personal high or low heart rate.

Setting these alerts is an important way to monitor your health passively.

And best of all, once you set up these alerts, you do not have to do anything else! You can set it and forget it–until you receive a notification.

When you turn these alerts on, your Fitbit notifies you when your heart rate goes above or below your personal heart rate threshold, even if for a short time.

Then you decide if action is required, i.e., calling your doctor, going to the ER, trying some deep breathing exercises for a few minutes, or taking another measurement.

So, let’s get to it and show you how to set these alerts up and customize them!

  1. “…when your body rests for at least 10 minutes” – That’s a critical bit of information that isn’t on the Sense packaging.

    I bought the Sense (instead of a Garmin), expecting that I will get a notification when the threshold is crossed PERIOD (active or inactive).

    Could Fitbit (Google) code an option that would remove the 10-minute inactivity condition so that people could get threshold notifications no matter their activity (or inactivity)?


    • Hi Mike,

      As far as we know, you cannot get around this 10 minute of inactivity period for a notification. What you can do instead is turn on heart zone notifications for each exercise you do with your Fitbit and the Exercise app. After you turn these on, each time you enter a new heart rate zone, your Fitbit notifies you with a set number of vibrations, indicating which zone you’re in: 1 buzz is below zone, 2 buzzes is fat burn zone, 3 buzzes is cardio zone, adn 4 buzzes is peak zone.

        Open the Exercise app on your Sense.
        Choose an exercise.
        Swipe up passed the Settings options and toggle on Heart zone notifications.
        Repeat for all exercise types you want this notification for

      The zones are set automatically using your age, but you can make custom zones via the Fitbit app.

        Open the Fitbit app, tap the Today tab and tap your profile picture.
        Scroll down to Settings section and choose Activity & Wellness.
        Tap Heart Settings.
        Under Exercise, choose Heart Rate Zones
        Create a custome zone with upper and lower limits and/or create a max heart rate used for the automatic zone creation

      Consider asking Fitbit to add this as a feature in an upcoming firmware release via their suggestions page.
