How to troubleshoot your apple watch’s heart rate sensor

The Apple Watch is a great fitness-tracking device because it can record both your GPS position and your heart rate. However, if for some reason you’re not getting any heart rate readings or it’s not being tracked consistently, here’s what to do.

How the Apple Watch Heart Rate Sensor Works

The Apple Watch uses green LEDs paired with photodiodes to track the blood flow through your wrist. Blood appears red because it reflects red light and absorbs green light (that’s physics for you!). So, by measuring how much green light is absorbed a few hundred times per second, your Apple Watch can track when your heart is beating. It can detect a heart rate range of between 30 and 210 beats per minute.

The Apple Watch also uses infrared LEDs for background heart rate tracking.

To force your Apple Watch to check your heart rate, put it on, and open the “Heart Rate” app. If you get a reading after a few moments, it means the problem is most likely tied to how you use or wear your Watch.

How to troubleshoot your apple watch’s heart rate sensor

My Watch detects my heart rate, so the sensor can’t be totally broken.

If you don’t get a reading, the heart rate sensor may be broken—or your Watch may need to be reset. Skip ahead to the section on resetting a Watch for instructions on how to do that.

How to troubleshoot your apple watch’s heart rate sensor

It’s not fun to see these error messages after a run.

Make Sure Heart Rate Tracking Is On

To get background heart rate readings, Wrist Detection must be enabled. On your iPhone, open the Watch app, go to “Passcode,” and check to see if “Wrist Detection” is turned on.

How to troubleshoot your apple watch’s heart rate sensor

If you’re relying on your Apple Watch to track your heart rate during workouts, you can’t use the Power Saving Mode. Open the Watch app on your iPhone, go to “Workout,” and make sure the Power Saving Mode is disabled.

How to troubleshoot your apple watch’s heart rate sensor

Check the Band and Positioning

To consistently track your heart rate, your Apple Watch needs to be able to detect it. If it’s not correctly positioned on your wrist, it’ll struggle to get reliable readings.

Apple recommends that your Watch is “snug, but comfortable.” It should stay fixed in place while you exercise, but it shouldn’t cut off blood flow. You might need to tighten it a little bit for workouts, especially if you don’t like the feeling of a tight band around your wrist throughout the day.

While what band you use shouldn’t affect the heart rate reading, it can affect how comfortable your Watch is when you wear it tight enough to get a good heart rate reading. The Sports Band, Sports Loop, Nike Sports Band, and Nike Sports Loop are all designed to be comfortable when worn tightly during exercise. The Sports Loops, in particular, are easy to adjust as needed.

Other bands, like the Leather Loop or Steel Link Bracelet, just aren’t as nice when you’re sweating.

How to troubleshoot your apple watch’s heart rate sensor

This worked for me and my hairy arms, at least while I run. Harry Guinness

Apple recommends you wear your Watch faceup on the top of your wrist. However, because of my hairy wrists, I actually got more consistent heart rate readings putting it on the underside of my wrists when I run. This shouldn’t be an issue for most people, but give it a shot if you’re struggling to get steady readings while running.

Factors That Can Affect Workout Heart Rate Tracking

A few factors can affect your Apple Watch’s ability to measure your heart rate.

Movement, especially dynamic movement, makes it harder for your Watch to measure your heart rate. It has an easier time tracking your heart rate during steady movements like walking or running, than during erratic workouts like boxing.

The LEDs and sensors are located on the bottom of the Watch. If dirt, grime, or sweat builds up, it can make them less effective. Give the bottom of your watch a wipe with a damp clean cloth.

Also, there are factors that make your heart rate harder to measure. The sensors detect surface blood flow and if blood flow is reduced to your wrist, it’s harder for the Watch to get a read. Cold weather is a big one here; theoretically, so are overhead gymnastic movements or any lifting that uses compression straps on your arms.

Reset Your Apple Watch

If after trying all the above suggestions, your Watch still fails to accurately detect your heart rate, the next step is to try resetting it.

How to troubleshoot your apple watch’s heart rate sensor

To reset a Watch, open the “Settings” app and go to General > Reset > Erase All Content and Settings. Enter your passcode, and follow the onscreen prompts to erase the Watch completely.

Then, using the “Watch” app on your iPhone, you’ll need to set it up again.

Contact Apple

If a hard reset doesn’t fix your Apple Watch, it’s possible that the sensor is broken. Contact Apple as the company may repair or replace it for you, if it’s still under warranty.

Read Full Bio »

One of the biggest attractions we have when buying an Apple Watch is that it not only allows you to see the time, receive notifications and even play, but it also incorporates interesting health features. In this article we will tell you what sensors each Apple Watch has, in addition to explaining what each one consists of.

Sensor types

Each Apple Watch has a multitude of sensors that are used for one thing or another. In addition to a microphone, speaker, processing chips or GPS, we highlight those that serve to perform some type of health measurement or help during sports training. Below we explain what all of them consist of, although making it clear that not all of them are present in each generation, as you will see in the following sections.

Ambient light sensor

This sensor basically allows the watch to keep its screen on or off, in addition to varying the brightness depending on the type of light you have at that time. For the latter, this option must be activated in the settings.

Accelerometer

This is the sensor that receives the movement stimuli. You may have ever wondered how the Apple Watch knows that you are standing, exercising or if you are asleep. Well, precisely this accelerometer is the one who is capable of detecting it.

Gyroscope

Like the previous one, this also helps to detect the movement of our body, knowing at all times if you are standing or not. Thanks to this, the Apple Watch can more accurately detect the movements of any part of the body even if the device itself is on the wrist. It should be noted that in its latest versions it can even detect falls.

Heart rate sensor

In this case we find three versions, the traditional heart rate sensor, the improved one (optical) and the one that also allows for electrocardiograms (electrical). The first two are capable of measuring the beats per minute of the heart and the last one detects electrical activity (Lead I) as long as the app dedicated to it is used and the finger is kept on the digital crown in which it is hosts.

Barometric altimeter

This sensor is capable of detecting the height at which you are, either above sea level or above the ground. Being barometric, it bases its measurements on the relationship between atmospheric pressure and altitude.

Compass

The homonymous application available in some watches is based precisely on the information obtained by this sensor. It is capable of working even without having WiFi or Mobile Data, since its functionality is to be able to say exactly where the north, south, east and west are. Wow, what has been a traditional compass of a lifetime but on a watch.

Blood oxygen sensor

The most recent devices of the brand have this sensor in charge of measuring the level of oxygen we have in the blood. It achieves this through a complex internal analysis mechanism that is performed in seconds after comparing data obtained with a beam of red light that is reflected in the veins.

Apple Watch sensors

Once the different sensors that an Apple watch can incorporate are known, it is necessary to know which of these incorporates each generation. As we have already told you before, not all the sensors mentioned are in all of them, although a good part is.

No, the sensors are not noticeable

If you have never had an Apple Watch, it is very likely that you are wondering if it shows when you take a measurement with any of these sensors, if you notice discomfort and even pain. The answer is blunt: no. The way to proceed with the measurements is completely silent, invisible and painless. Maybe you can see a green or red beam of light depending on the measurement, but having the watch in continuous contact with the wrist is hardly noticeable.

How to know if the sensors are working

In those related to health, just look at the results. If you see that they are strangely anomalous or that they cannot even be carried out accurately, there is a possibility that you do not have the device correctly positioned or you have not followed the instructions for use. However, there is also the possibility that one of these is defective, especially if the watch has suffered a blow.

The way to solve it is by going to Apple’s technical service or, failing that, to an authorized one. There they will be able to verify more exactly what is the origin of the problem. If the failure is due to a problem other than misuse and the device is also under warranty, it is very possible that you will receive a replacement without any additional cost.

There is also the possibility that a software failure prevents the correct operation of any of these sensors, so it is recommended to always have the latest version of watchOS installed. On the other hand, there is also the possibility that certain measurements are not enabled in your territory, such as ECGs.

You can enable notifications from the Heart Rate app on your Apple Watch to alert you to high or low heart rates and irregular heart rhythms.

How to troubleshoot your apple watch’s heart rate sensor

High and low heart rate notifications

If your heart rate remains above or below a chosen beats per minute (BPM) while you appear to have been inactive for a period of 10 minutes, your Apple Watch can notify you. These notifications are available only on Apple Watch Series 1 or later for ages 13 and up.

You can turn on heart rate notifications when you first open the Heart Rate app on your Apple Watch, or at any time later from your iPhone:

  1. On your iPhone, open the Apple Watch app.
  2. Tap the My Watch tab, then tap Heart.
  3. Tap High Heart Rate, then choose a BPM.
  4. Tap Low Heart Rate, then choose a BPM.

Learn from the American Heart Association about what can cause a high heart rate or a low heart rate.

Irregular rhythm notifications

The irregular rhythm notification feature on your Apple Watch will occasionally look at your heartbeat to check for an irregular rhythm that might be suggestive of atrial fibrillation (AFib). Learn how to enable irregular rhythm notifications. Irregular rhythm notifications are currently available only in certain countries and regions. Learn where irregular rhythm notifications are available.

Here’s what you need to enable irregular rhythm notifications

  • Make sure that notifications are available in your country or region. Learn where irregular rhythm notifications are available.
  • Update your iPhone to the latest version of iOS and Apple Watch to the latest version of watchOS.
  • These notifications are not designed for people who have been diagnosed with AFib.
  • These notifications are not intended for use by people under 22 years old.

How to troubleshoot your apple watch’s heart rate sensor

How to enable irregular rhythm notifications

  1. Make sure that the software on your iPhone and Apple Watch is up to date.
  2. On your iPhone, open the Health app.
  3. Tap the Browse tab, then go to Heart > Irregular Rhythm Notifications.
  4. Once enabled, you can turn irregular rhythm notifications on or off in the Apple Watch app on your iPhone: Open the Apple Watch app, tap the My Watch tab, then go to Heart > Irregular Rhythm.

What to do when you receive an alert

If you receive a notification, the irregular rhythm notification feature on your Apple Watch identified an irregular rhythm suggestive of AFib and confirmed it with multiple readings.

If you have not been diagnosed with AFib by a physician, you should talk to your doctor.

How irregular rhythm notifications work

The irregular rhythm notification feature on your Apple Watch will occasionally look at your heartbeat to check for an irregular rhythm that may be AFib. This usually happens when you’re still to ensure a more accurate reading. Depending on how active you are, the number of readings collected each day and the time between these readings will vary.

What is AFib

AFib is a type of irregular heart rhythm. AFib occurs when the heart beats in an irregular pattern. It’s a common form of irregular heart rhythm where the upper chambers of the heart beat out of sync with the lower chambers.

According to the CDC, approximately 2% of people younger than 65 years old and 9% of people 65 and older have AFib. Irregularities in heart rhythm become more common as people get older. Some individuals with AFib don’t experience any symptoms. Others experience symptoms that could include rapid heartbeat, palpitations, fatigue, or shortness of breath.

AFib can be temporary or persistent, and people with AFib often live healthy, active lives. AFib episodes can be prevented through regular physical activity, eating a heart-healthy diet, maintaining a healthy weight, and treating other medical conditions that could worsen AFib. If left untreated, AFib can lead to heart failure or blood clots that may lead to stroke. AFib can be managed with a doctor’s care and medication, and early diagnosis and treatment can prevent such complications.

Learn how Apple Watch measures your heart rate, and get tips for a more accurate reading.

How to check your heart rate

How to troubleshoot your apple watch’s heart rate sensor

You can check your heart rate any time using the Heart Rate app. Open the app, then wait for Apple Watch to measure your heart rate. You can also view your resting, walking, breathe, workout, and recovery rates throughout the day. To easily open the app, add the Heart Rate complication to your watch face or add the Heart Rate app to the Dock.

You can also turn on heart rate notifications, so you know if your heart rate remains above or below a chosen beats per minute (BPM), or to occasionally check for an irregular heart rhythm.

Irregular rhythm notifications are available only with watchOS 5.1.2 or later. To enable irregular rhythm notifications, the notifications must be available in your country or region and you must be in the country or region where you purchased your device. Learn where irregular rhythm notifications are available.

When Apple Watch measures your heart rate

How to troubleshoot your apple watch’s heart rate sensor

When you use the Workout app, Apple Watch measures your heart rate continuously during the workout and for 3 minutes after the workout ends to determine a workout recovery rate. If you don’t see your heart rate, check your settings.

This information, as well as other data it collects, helps Apple Watch estimate how many calories you’ve burned. In addition, Apple Watch measures your heart rate throughout the day when you’re still, and periodically when you’re walking (Apple Watch Series 1 or later). Since Apple Watch takes these background readings based on your activity, the time between these measurements will vary. Apple Watch also calculates a daily resting rate and walking average by correlating background heart rate readings with accelerometer data when sufficient background readings are available. You can control which third-party apps have access to your health data from the Health app in Sources.

Some anomalies may appear in the displayed data, resulting in occasional heart rate measurements that are abnormally high or low.

How Apple Watch measures your heart rate

The optical heart sensor in Apple Watch uses what is known as photoplethysmography. This technology, while difficult to pronounce, is based on a very simple fact: Blood is red because it reflects red light and absorbs green light. Apple Watch uses green LED lights paired with light‑sensitive photodiodes to detect the amount of blood flowing through your wrist at any given moment. When your heart beats, the blood flow in your wrist — and the green light absorption — is greater. Between beats, it’s less. By flashing its LED lights hundreds of times per second, Apple Watch can calculate the number of times the heart beats each minute — your heart rate. The optical heart sensor supports a range of 30–210 beats per minute. In addition, the optical heart sensor is designed to compensate for low signal levels by increasing both LED brightness and sampling rate.

The optical heart sensor can also use infrared light. This mode is what Apple Watch uses when it measures your heart rate in the background, and for heart rate notifications. Apple Watch uses green LED lights to measure your heart rate during workouts and Breathe sessions, and to calculate walking average and Heart Rate Variability (HRV).

How to troubleshoot your apple watch’s heart rate sensor

Apple Watch Series 4, Series 5, Series 6, or Series 7* also have built-in electrodes in the Digital Crown and the back of Apple Watch, which can measure the electrical signals across your heart when used with the Heart Rate app or the ECG app. When you place your finger on the Digital Crown, it creates a closed circuit between your heart and both arms, capturing the electrical impulses across your chest.

To use the electrical heart sensor to measure your heart rate, open the Heart Rate app and place your finger on the Digital Crown. You will get a faster reading with higher fidelity — getting a measurement every second instead of every 5 seconds. You’ll see "ECG" in Heart Rate Context when looking at recorded data for Heart Rate in the Health app. You can also use the electrical heart sensor to take an ECG with the ECG app.

*ECG isn’t supported on Apple Watch SE. The ECG app is currently available only in certain countries and regions. Learn where the ECG app is available.

For best results

Start with a good fit. Even under ideal conditions, Apple Watch may not be able to get a reliable heart rate reading every time for everybody. And for a small percentage of users, various factors may make it impossible to get any heart rate reading at all. But there are things you can do to help Apple Watch get the most consistent and best heart rate readings possible. Learn what else affects your reading.

If you have not yet done so, update your iPhone and Apple Watch to the latest compatible software versions, starting with your iPhone:

On your iPhone, in the Watch app, go to: My Watch > Privacy – check that Fitness Tracking and Heart Rate are enabled.

On your iPhone, in the Watch app, go to: My Watch > Workout – turn off Power Saving Mode.

Check that Wrist Detection is turned on and that, if passcode is enabled, you are unlocking your Apple Watch after placing it on your wrist:

  • On your iPhone, in the Watch app, go to: My Watch (tab) > Passcode > turn Wrist Detection on.
  • Note that Wrist Detection can be affected by temporary or permanent skin changes, such as by some wrist tattoos.

Check that you are wearing your Apple Watch sufficiently snugly on the top of your wrist (it may otherwise believe that it has been removed, causing it to lock):

Close certain apps and then restart (normally) both your iPhone and your Apple Watch:

  • Close the Watch app, Activity app and Health app (if open) on your iPhone:
    • Double-click the Home button, then swipe up on each app preview to close the apps.

    If you have previously used any third-party fitness tracking, sleep tracking or heart rate monitoring apps:

    • Check whether there is an active or paused session within any of them.
    • If there is, then end that session from within that app on your Apple Watch.
    • If in doubt, it may help to remove any such third-party apps from your Apple Watch, at least temporarily.

    If the issue persists, then it may help to unpair and re-pair your Apple Watch:

    • The Watch app on your iPhone takes a backup of your watch automatically when unpairing via the app.
    • Initially choose to Restore from Backup during set up (most data and settings will be restored, with some exceptions, such as Apple Pay cards, passcode).
    • If the issue persists, consider instead unpairing and setting it up as a new watch.

    If the issue persists, then I suggest that you contact Apple Support (remote diagnostics and/or mail-in service may be available, if required), make a Genius Bar reservation or visit an Apple Authorised Service Provider for assistance:

Носите Apple Watch правильно — затяните ремешок не слишком туго, чтобы Ваша кожа дышала, но часы плотно прилегали к руке. Так Вам будет удобно носить их, а датчики будут работать максимально точно. Подробнее см. в статьях службы поддержки Apple Ношение Apple Watch и Отслеживание пульса с помощью Apple Watch.

    Your Apple Watch uses the personal information that you provide to help calculate metrics for your daily activity. You can further improve its accuracy using these tips.

    Keep your personal information up to date

    Your Apple Watch uses your personal information — such as your height, weight, gender, and age — to calculate how many calories you burn and more.

    How to troubleshoot your apple watch’s heart rate sensor

    To update your personal information, open the Apple Watch app on your iPhone. Tap the My Watch tab, then tap Health > Health Profile. Tap Edit, then tap the item that you want to change.

    Make sure that you earn Move and Exercise credit

    Every full minute of movement that equals or exceeds the intensity of a brisk walk counts toward your daily Exercise and Move goals. With Apple Watch Series 3 or later, your cardio fitness levels are used to determine what is brisk for you. For wheelchair users, this is measured in brisk pushes. Any activity below this level counts only toward your daily Move goal.

    To make sure that you earn Exercise credit during walks, allow the arm with your Apple Watch to swing naturally. For example, while walking your pet, let the arm with your watch swing freely while the other holds the leash.

    If you need both hands while walking, for example to push a stroller, you can still earn Exercise credit with the Workout app. Open the app on your Apple Watch and tap Outdoor Walk. The Activity app relies on arm motion and an accelerometer to track movement, but the Workout app can use the accelerometer, the heart rate sensor, and GPS.

    Make sure that Wrist Detection is on

    If Wrist Detection is off, you won’t get Stand notifications, and your Apple Watch can’t track your Stand progress. Background heart rate readings (like resting and walking rates) won’t be taken if Wrist Detection is off.

    To check the setting, open the Apple Watch app on your iPhone. Tap the My Watch tab, then tap Passcode. Make sure that Wrist Detection is on.

    Resting and walking rates are available only on Apple Watch Series 1 or later.

    Check the fit

    Wearing Apple Watch with the right fit — not too tight, not too loose, and with room for your skin to breathe — keeps you comfortable and lets the sensors do their job.

    You might want to tighten your Apple Watch band for workouts, then loosen it when you’re done. In addition, the sensors will work only if you wear your Apple Watch on the top of your wrist.

    Get the most accurate heart rate measurement

    To get the most accurate heart rate measurement when you use Workout, make sure your Apple Watch fits snugly on top of your wrist. The heart rate sensor should stay close to your skin. Learn about the accuracy and limitations of the heart rate sensor.

    If you have an Apple Watch Series 3 or later, set up Cardio Fitness Levels to measure how hard your heart is working during an outdoor walk, run, or hike in the Workout app.

    If you turn on Power Saving Mode during a walking or running workout, the heart rate sensor turns off. To see if Power Saving Mode is off or on, open Settings on your Apple Watch, then tap Workout. You can also find this setting in the Apple Watch app on your iPhone.

    If you turn off Heart Rate in Privacy settings, you also won’t get a heart rate measurement. To see if Heart Rate is off or on, open the Apple Watch app on your iPhone, then tap Privacy.

    Choose the best workout

    When you use the Workout app, choose the option that best matches what you’re doing. For example, if you’re running on a treadmill, choose Indoor Run. If you’re doing a workout that isn’t listed, like strength training, choose Other.

    Learn about each workout.

    Calibrate your Apple Watch

    Calibrate your Apple Watch to improve the accuracy of your distance, pace, and calorie measurements. Calibrating your watch can also help it learn your fitness level and stride.

    What else affects your heart rate reading

    Many factors can affect the performance of the Apple Watch heart rate sensor. Skin perfusion (or how much blood flows through your skin) is one factor. Skin perfusion varies significantly from person to person and can also be impacted by the environment. If you’re exercising in the cold, for example, the skin perfusion in your wrist might be too low for the heart rate sensor to get a reading.

    Permanent or temporary changes to your skin, such as some tattoos, can also impact heart rate sensor performance. The ink, pattern, and saturation of some tattoos can block light from the sensor, making it difficult to get reliable readings.

    Motion is another factor that can affect the heart rate sensor. Rhythmic movements, such as running or cycling, give better results compared to irregular movements, like tennis or boxing.

    If you’re not able to get a consistent reading because of any of these factors, you can connect your Apple Watch wirelessly to external heart rate monitors such as Bluetooth chest straps. Learn how to pair Bluetooth accessories.

    Heart rate is one of many factors that Apple Watch uses to measure your activity and exercise. Depending on your workout, it selects the most appropriate inputs for that activity. For example, when you’re running indoors, it also uses the accelerometer. Learn more about how your Apple Watch uses GPS and the heart rate sensor when you use the Workout app.

    How to fix an erratic heart rate monitor? Can be doing same exercise at 70-80 BPM, then the monitor suddenly jumps to 150 BPM for a few minutes, for no reason.

    Apple advises that, even under ideal conditions, Apple Watch may not be able to record a reliable heart rate reading every time for everybody.

    For the best performance from the heart rate sensor during workouts, ensure that you wear your watch snugly on the top of your wrist. Apple suggests that you consider tightening the band before starting a workout and loosening it again afterwards:

    Keep in mind that the heart rate sensor is likely to give better results for workouts that involve rhythmic (eg running) rather than irregular movements.

    For workouts that involve flexing your wrist, it may also help to move your watch a little higher up your arm, away from the flexing joint, to help it maintain good skin contact.

    Other issues that can impact sensor performance include skin perfusion and wrist tattoos.

    If you continue to experience issues with recording your heart rate, for more consistent readings, you may wish to consider pairing an external heart rate monitor / Bluetooth chest strap to your watch:
