Users are Reporting that the Fitbit Sense Displays an Erroneous Heart Rate. Is there a Way to Fix it?

There is unquestionably a problem. During physical activity, the heart rate of many users of the Fitbit Sense has been inaccurately tracked. These issues vary from delays in reporting to outrageously wrong measurements. This post will discuss some of the more frequent solutions to the problem.

The Fitbit Community forums were the first place people shared any of this information. In point of fact, there are several posts on Sense dedicated to the discussion of faulty heart rate tracking. One of these has received almost 400 answers already! There aren’t very many long threads on the boards to be found. If you go to the community sites for Sense, you’ll see that this particular issue is probably the one most people have complaints about.

Users are not reporting too many issues with their resting heart rates or heart rates during activities of low intensity. The issues manifest themselves during physically demanding activities like jogging, lifting weights, or cycling. Which kind of negates the point of having a fitness tracker in the first place.

It is primarily because one cannot link a Fitbit to an external heart rate monitor like a chest strap or wristband in any way, shape, or form. These kinds of gadgets are not impacted by hand and arm motions, which can affect the accuracy of a watch’s reading of the wearer’s heart rate. And Fitbit has not disclosed any information regarding its potential plans to develop its very own chest strap, which is unfortunate because accomplishing that will fix all the problems.

In most cases, users have reported that the readings during strenuous exercise are far lower than expected.

“My heart rate varies all over the place. I will be engaging in interval training, during which my heart will be pounding out of my chest even though my watch will show that I am in the “under the zone.” One customer says, “The funny thing is that if I get off the machine and walk a few steps, the rate immediately increases.”

An even more severe remark was provided by someone else, who said, “I’m sorry to say, but my view is that Sense heart rate detector is virtually a producer of random numbers.”

“I’m participating in a study at the university. They use a polar heart monitor to keep track of my heart rate. And even though the polar indicates my heart rate is 120 beats per minute, my Fitbit intuition puts it at about 83. Another person concludes that they “weren’t expecting that huge of a change.”

What exactly is going on with Sense, then? It’s interesting to note that the issue doesn’t manifest itself on other Fitbits, including the Versa, Charge, any of the Inspire models, or the Luxe. Not even close, at least not to the same degree. The ability to monitor one’s heart rate using one’s wrist is not yet on par with monitoring one’s heart rate using an external chest strap. But it shouldn’t be too far off.

Fitbit has not yet commented on the issue in an official capacity. And it can’t be denied that there is one. One user, however, has shared a response that she got from the Team, which reads as follows: “Thanks for letting us know about this issue. We are aware of the situation and are actively working to find a solution as quickly as possible.

Therefore, it is clear that the firm is aware that something fishy is going on. This indicates that there may be nothing you can do to remedy the situation at this time. It’s possible that there’s a glitch in the software, so here’s hoping an upgrade to the firmware can provide a solution soon. Because the heart rate sensor that is present in the Sense can also be found in other Fitbits, we do not believe that the hardware is the root of the problem.

The most typical solutions to the problem are what we have available right now; we hope that one of these will be successful for you.

However, let’s begin with the fundamentals first.

How Can I Record my Heart Rate with my Fitbit Device?

A good investment would be purchasing a Fitbit smartwatch or fitness tracker that has a built-in heart rate sensor. These kinds of devices can tell you your resting heart rate, which is maybe the most accurate measure of how your health and fitness are doing overall. It is generally accepted that lower levels are connected with improved cardiovascular health and even increased longevity.

Heart rate-enabled gadgets also allow you to work out inside a heart rate zone. The vast majority of equestrian athletes make use of this. They are able to accomplish their full potential in the shortest period of time possible by practicing in a heart rate zone that permits them to do so. It is crucial to understand how hard your heart needs to be worked when it comes to getting the most out of your workout.

A scant few years ago, fitness trackers that included a heart rate monitor were virtually nonexistent. It has now evolved into the industry standard. On the order of $20 to $30, even relatively inexpensive devices have heart rate monitors already integrated into them. Some of the more advanced models will even sound an alarm to notify you if they detect any anomalies in your heartbeat or if your heart rate when you are at rest is either too low or too high.

You could be curious about the method that these devices use to measure heart rate. When taking measures, the wrist is an excellent location to start. The capillary area is illuminated with LEDs at a rate of many times per second by the wearable device. Fitbit employs green LEDs. This is a green light most of the time, although it could be red or a combination of the two at any given moment. Infrared light is also used to assess when the wearable device is appropriately positioned on the user’s wrist.

The sensor measures the motion of your capillaries through the utilization of light-sensitive photodiodes. They vary in size in response to the volume of blood flowing through them. This enables them to determine your heart rate in beats per minute, which is more commonly abbreviated as bpm. Fitbits can monitor heart rates that extend from 30 to 220 beats per minute.

How to Wear your Fitbit so that it Can Provide the Most Accurate Readings of your Heart Rate

If you want an accurate reading of your heart rate, you must ensure that you are correctly wearing your Fitbit to get a decent read on it. This is probably the most critical thing to know. You need to be aware of nothing particularly noteworthy to utilize it daily. Always keep your Fitbit in the same spot, right above your wristbone, where it belongs.

Your wrist will move more frequently while you work out because of the increased activity. In addition, there is a possibility of slippage. To receive an accurate reading, you need to ensure that the gadget is correctly positioned on your skin and in close touch with it. However, you should not make the mistake of wearing it excessively tightly, as this could potentially restrict blood flow.

Fitbit also recommends that you wear the gadget to be a finger’s breadth above your wrist bone when you are exercising. This is because the device will move less when placed in this position, resulting in more accurate results.

But despite this, there are several circumstances in which monitoring the heart rate can be difficult. Fitbit provides a list of some of these, including the ambient temperature, the user’s stress level, the amount of alcohol or caffeine consumed, their immune reaction to disease, and their medications. For instance, working out while the temperature is low can make monitoring one’s heart rate more challenging. This is because exposure to cold weather can alter the blood volume that passes through the skin. You do not have any control over any of this, and there is nothing you can do about it.

That brings us to the end of our discussion. You are limited to little more than checking that the device is being worn appropriately. This is because there is a possibility of sweat, filth, and grime building, all of which have the potential to interfere with the heart rate sensor. The one other thing that you should clean regularly is the underside of the gadget. Just wipe away any filth that you find. People should do this with clean water and a cleaner that does not contain any soap. Using soap, sanitizer, or household cleanser would be a grave error.

Other Issues that Commonly Arise with Heart Rate Monitors like Fitbits

What’s Wrong with my Fitbit? It’s Supposed to be Recording my Heart Rate

Things can go wrong, and when they do, the otherwise reliable device that is attached to your wrist will cease monitoring your heart rate, and the lights on the sensor will stop flashing. The next step is as follows.

If you are having issues with a Fitbit gadget, the first thing you should do is the power it down entirely and then start it back up again. If the screen on your wearable device is unresponsive, if it is unable to connect to the app, or if it is not monitoring your activities, this is the remedy you should do. Check out our instructional guide on resetting your Fitbit fitness tracker or smartwatch if you are unsure how to carry out these steps.

This might or might not be the solution to the problem. If you tried it the first time and it didn’t work, you should give it another attempt or two before giving up completely.

The following step that you can take is to charge the battery to its maximum potential completely. This is because the sensor may turn off automatically if the battery is becoming dangerously low, which can cause problems with recording the user’s heart rate.

Be Sure that the Function to Track your Heart Rate is Activated!

Verify that the function that monitors your heart rate is turned on, even if this may appear to be stating the obvious. This is set to be active on your Fitbit by default; however, you may have deactivated it.

On smartwatches, confirm that the option is turned on by accessing the Settings app on the device and toggling it to the “On” position (“On” or “Auto” for Blaze). Ensure the “Auto” setting is selected for your heart rate monitor if you have an Alta device or an earlier generation of Charge.

What to Do if your Fitbit Heart Rate Screen is Gray, Blank, or Stuck?

If the readout for your heart rate on your watch is blank, frozen, or grayed out, this indicates that the device most likely does not have a strong signal. When you move your arm forcefully, you might experience this issue occasionally.

A reading that is obscured by gray indicates that the Fitbit is trying to establish a more robust connection. Please give the tracker a few moments to get a more accurate readout. After that, things should go back to how they were before.

Additional Useful Hints

We sincerely hope that one of these suggestions was able to resolve the issue. If you’ve gone through all the procedures in this post and nothing has helped fix the problem with recording your heart rate, you could wish to give your Fitbit a fresh start to see if that fixes the issue. This is the answer that everyone looks to when they have a problem. The last possibility is that there is something wrong with your device. If you think this might be the case, you should get in touch with the customer support team at Fitbit as soon as possible.
