How to set high and low heart rate notifications on your Fitbit Sense, Versa 3, or Charge 5

high heart rate notification on Fitbit Versa 3 and Sense

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 types of alerts is an important way you can passively monitor your health.

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. And then you decide if action is required, i.e., calling your doctor, going to the ER, try 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!

Getting heart rate notifications while exercising?

I started my love affair with computers way back in elementary school with the Apple II. Since then, I've worked with technology in my career as a media educator and videomaker. I have an MFA in media making from Temple University, where I also taught undergrads as an adjunct faculty member. So I know a thing or two about teaching others and creating how-to guides! After a cancer diagnosis, I turned to mobile technology like my Apple Watch to help me monitor my health throughout my chemotherapy treatment and later, to regain my wellness once in remission. I love sharing how to understand and use mobile tech, like smartwatches and phones, as a tool for empowerment to live our best and healthiest lives!
