Monitor your heart rate on your Samsung smartwatch
The lower your heart rate is during exercise, the more in shape you are and vice versa. Use your smart watch to keep track of your heart rate whenever you work out or go for a jog, so you can see how far you have come.
Note: Information provided applies to devices sold in Canada. Available screens and settings may vary for smartwatches sold in other countries. This device and related software are not intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease. If the watch becomes hot to the touch, remove it until it cools down. Do not look directly at the heart rate sensor's lights. Doing so may impair your vision.
Samsung Health measures your heart rate using lights and sensors located on the back of your watch. But you will need to make sure you are doing things properly to get the best measurement results. Check out the following information:
- For a mid-workout measurement, take a brief break before taking your heart rate.
- Take measurements when seated and when you are relaxed for the most accurate reading.
- Do not move your body while taking heart rate measurements. Doing so may cause your heart rate to be recorded inaccurately.
- If the measurement is very different from the expected heart rate, rest for 30 minutes and then measure it again.
- If your heart rate is extremely high or low, measurements may be inaccurate.
- Wear the smartwatch snugly above the wrist. Do not fasten the watch band too tightly. Avoid attaching third-party bands to your watch, and only use the band included with your watch or a Samsung-approved band specifically designed for it.
- Measurements may need to be repeated at least five times for the most accurate results.
- Remove the protective plastic from the heart rate measurement sensor before taking measurements.
- If the heart rate sensor is not working properly, wipe the sensor, and adjust the position of the watch to sit above your wrist.
Even if you are wearing your smartwatch or fitness band correctly, certain factors may affect how well your heart rate is read. If you are having trouble getting an accurate measurement, review this information:
Environmental factors that cause inaccuracy
- The heart rate figures may not be accurate depending on measurement conditions and surroundings.
- If heart rate measurements are taken at low temperatures, the results may be inaccurate. Keep yourself warm when measuring your heart rate.
- If the heart rate sensor is dirty, wipe the sensor with a soft, clean, dry cloth and try again.
- Obstructions between the watch band and your wrist, such as body hair, dirt, or other objects may prevent the light from reflecting evenly.
Other factors
- Smoking or consuming alcohol before taking measurements may cause your heart rate to be different from your normal heart rate.
- Do not talk, yawn, or breathe deeply while taking heart rate measurements.
- Users with thin wrists may receive inaccurate heart rate measurements with the watch.
- Heart rate measurements taken for infants and toddlers may be inaccurate.
Note: You cannot manually measure your heart rate on the Galaxy Fit. Available features, menu options, and settings will vary by the watch and software version.
Want to see if your heart rate has become faster or slower after a workout? You can manually measure your heart rate any time you need to. Just remember to read the guidelines mentioned above before measuring.
- Galaxy Watch models: On your watch, navigate to and tap Samsung Health. Swipe to and tap Heart rate, and then tap Measure.
- Fitness bands: Swipe to and tap the Heart rate tracker, and then tap Measure.
Note: If your watch or fitness band is set to always measure your heart rate, your current measurement will display instead of "Measure".
Note: Maybe frequent or manual heart rate measurements are not enough. Maybe you want to know your heart rate at all times. No worries, you can set your smartwatch or fitness band to continuously measure your heart rate.
- Galaxy Watch4 and Galaxy Watch4 Classic: Navigate to and open Samsung Health on your smartwatch. Swipe to the very bottom of the screen, and then tap Settings. Tap Measurement and make sure you are under the Heart rate section.
- Previous smartwatch models: Press the Home key (or Power key) on the watch, and then navigate to and tap Samsung Health. Swipe to and tap Heart rate, and then swipe to the bottom of the screen. Tap HR and stress measurement or Auto HR settings.

- Gear Fit2 and Gear Fit2 Pro: Press the Power key on the watch, and then swipe to and tap Auto HR.
- Measures continuously or Always: Measures your heart rate continuously. Choose this option if you do not want to worry about your watch missing your measurements.
- Every 10 mins while still or Frequent: Measures your heart rate every 10 minutes when you are still.
- Manual measurement only or Never: Measure your heart rate manually.
With the Galaxy Watch series, you can receive HR alerts from your watch if your heart rate is above a certain level for 10 minutes when resting.
Note: HR alert settings is only available for the Galaxy Watch4, Galaxy Watch3, Galaxy Watch Active2, Galaxy Watch Active, Galaxy Watch, and Galaxy Fit.
Note: For a Galaxy Fit or Galaxy Fit2, you can only manage High HR alert settings. To do so, open the Galaxy Wearable app on your phone, tap Samsung Health setting, and then tap High heart rate alerts.
Note: Sometimes you feel like your heart rate has improved during your jogs, but other times you feel out of breath. You can view your overall heart rate trends to find patterns and enhance your performance.
