Supported Samsung Galaxy Watch models can measure heart rate through Samsung Health. You can take a manual reading or, depending on the model and settings, choose continuous tracking or periodic readings while you are still. Automatic tracking is not guaranteed to be enabled: check the setting on your watch if readings are not appearing.
How Galaxy Watch heart-rate tracking works
The watch uses lights and sensors on its back to measure heart rate, with readings handled through Samsung Health. Samsung describes three measurement options, though their names and availability can vary by watch model, software version, and region.

| Mode | What it does |
|---|---|
| Continuous or always | Measures heart rate continuously. |
| Periodic while still | Measures every 10 minutes while you are still. |
| Manual only | Measures when you start a reading yourself in Samsung Health. |
The 10-minute interval is Samsung’s description of that setting, not an independent accuracy or performance rating. Samsung’s cited instructions do not establish a universal battery-life effect for each mode.

How to turn on automatic readings or take a manual measurement
Choose an automatic measurement mode
Settings differ by model. On Galaxy Watch8 and Galaxy Fit3, Samsung’s Gulf guide describes this route in the Wearable app: Watch settings > Health > Heart rate, then choose a measurement cycle. The guide is specific to those models; menus and feature support may differ elsewhere. Samsung Gulf’s setup guide was last updated September 23, 2026.

On some Wear OS watches, Samsung’s US instructions place the setting in Samsung Health on the watch. Earlier generations may use labels such as “HR and stress measurement” or “Auto HR settings.” Use the instructions for your exact model rather than assuming one menu path applies to every Galaxy Watch. If the watch is set to manual-only, it will not take automatic readings as expected.
Start a reading manually
For Galaxy Watch models covered by Samsung’s US support instructions, open Samsung Health > Heart rate > Measure. The reading may be less useful if you are moving or the sensor is not seated against your skin.

How to get a more dependable reading
- Wear the watch snugly, with the back sensor in direct contact with your skin. Samsung’s model-specific Gulf guide recommends placing it about one finger’s width above the wrist bone, toward the elbow.
- For a resting measurement, sit comfortably, relax, and keep still while the watch measures.
- If checking during exercise, take a brief break and remain still for the measurement.
- Check placement and fit if readings seem inconsistent. Samsung says skin condition, activity, settings, environmental conditions, placement, user configuration, and other user interactions can affect readings. It also notes that people with thin wrists may receive inaccurate measurements.
These are steps to improve measurement conditions, not a guarantee of accuracy. Samsung does not provide a universal accuracy percentage for Galaxy Watch heart-rate readings in the cited support material.

What heart-rate tracking can—and cannot—tell you
Heart-rate tracking is a wellness feature, not a diagnosis. Samsung cautions that information from the watch, Samsung Health, or related software is not intended to diagnose, cure, mitigate, treat, or prevent disease. Do not use a watch reading as a substitute for professional medical care.
Heart-rate tracking is also distinct from features such as ECG or blood-pressure measurement; availability and requirements for those features can differ. Samsung’s India support page, updated August 22, 2022, also describes the measurement modes and health-management limitation: How Samsung Health monitors your heart rate.
