Galaxy Watch Active2 - Monitor your heart rate (SM-R820 & SM-R830)

The lower your heart rate is during exercise, the more in shape you are - and vice versa. Use your smart watch or fitness band to keep track of your heart rate whenever you work out or go for a jog, so you can see how far you’ve come. Please, do not look directly at the heart rate sensor's lights. Doing so may impair your vision.

Available screens and settings may vary by provider, phone, or watch.

For the best measurement results

Samsung Health measures your heart rate using lights and sensors located on the back of your watch. But you’ll need to make sure you're doing things properly to get the best measurement results. Check out the information below:

  • 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 watch 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 specific 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 measurement is not working properly, adjust the position of the watch on your wrist.
Factors that cause heart rate inaccuracy

Even if you are wearing your smart watch 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 the information below.

# 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.
Manually measure your heart rate using your watch

Just be aware that if your smart watch is set to always measure your heart rate, your current measurement will display instead of Measure.

Automatically measure your heart rate

Maybe frequent or manual heart rate measurements aren’t enough. Maybe you want to know your heart rate at all times. No worries, you can set your smart watch to automatically measure your heart rate. From the watch's Home screen, swipe left until you reach the Heart rate widget. The widget should be availabe by default on your watch but you can add the widget anytime if required. Tap the screen once. Then, scroll down and tap HR and stress measurement. Select Measure continuously and your watch will measure your heart rate continuously whenever you are wearing it.

Other options are also available. If you select Every 10 mins while still, you watch will measure your heart rate regularly when you are still. You can also select Manual measurement only and you watch will measure you heart rate only when you tap Measure on the screen.

Track your heart rate measurement trends

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 see if your hunch is right. On the connected phone, navigate to and open the Samsung Health app, and then swipe to and tap Heart rate. From the Latest tab, you can see the latest heart rate measured.

Track your heart rate measurement trends

To see a summary of your past heart rate measurements, tap the Trends tab. You can select the date you want to view your heart rate trends, or sort it by days, weeks, and months. You can also sort by the activities, such as General or Resting, that recorded your heart rate.
