Your Galaxy S23 is the companion screen, not the heart-rate sensor in Samsung’s documented Samsung Health workflow. To measure and track heart rate in Samsung Health, pair the phone with a compatible Galaxy Watch and use the watch’s heart-rate sensor. You can then view connected health data on the S23.
Can a Samsung S23 measure your heart rate?
Samsung’s support documentation says Samsung Health measures heart rate using the sensor on a Galaxy Watch. It does not describe the S23 itself as the measurement device. So, for Samsung Health heart-rate readings, you need a compatible Galaxy Watch; the S23 is used to view and manage connected information.

Samsung has not established in the cited support guidance whether every S23 variant has any separate heart-rate sensing capability. The practical answer for Samsung Health is to use a compatible watch rather than expect the phone to take the reading.

How to check heart rate on a Samsung Galaxy S23
- Pair a compatible Galaxy Watch with your S23. Complete the watch’s paired-device setup using Samsung’s current on-device instructions.
- Measure on the watch. Open Samsung Health on the Galaxy Watch and use its heart-rate measurement function. The watch sensor collects the reading.
- View connected data on the phone. Open Samsung Health on the S23 to review health information synced from the paired watch. Exact screens and labels can vary by software version, so follow the menus shown on your devices.
Samsung’s support article, “How Samsung Health monitors your heart rate?”, describes this watch-based measurement workflow.

Choose how often the Galaxy Watch measures heart rate
Samsung documents three heart-rate measurement modes in Samsung Health. Choose the mode that matches whether you want ongoing tracking, periodic readings while resting, or readings only when requested. Samsung may change setting locations or labels between software versions; check the current Samsung Health menus on your watch.
| Samsung-documented mode | What it does | Best suited to |
|---|---|---|
| Continuous / Always | Measures heart rate continuously. | Ongoing tracking, including when you want more continuous data. |
| Frequent | Measures every 10 minutes while you are still. | Periodic checks without continuous measurement. |
| Manual / Never | Measures only when you start a reading manually. | On-demand checks. |
The “every 10 minutes while still” interval is Samsung’s stated device behavior for the Frequent mode, not a medical monitoring guarantee.

Samsung Health heart rate is different from Samsung Health Monitor
Basic heart-rate tracking in Samsung Health should not be confused with ECG, irregular rhythm notifications, blood-pressure features, or sleep-apnea features associated with Samsung Health Monitor. Health Monitor is a separate companion app for compatible Galaxy Watches and Samsung phones, and Samsung says it is available through the compatible paired-device setup rather than as a stand-alone download.
Health Monitor functions have separate supported-device and country or region requirements. For example, Samsung’s US support guidance says ECG is not intended for people under 22 and is not a substitute for traditional diagnosis or treatment. Check Samsung’s current local compatibility information before relying on any Health Monitor feature.

Samsung’s documented Samsung Health workflow uses a Galaxy Watch’s heart-rate sensor, so the S23 alone is not the documented way to obtain these readings. Samsung also publishes compatibility guidance for Bluetooth Low Energy (BLE) heart-rate-monitor accessories, but compatibility should be checked for the exact accessory, app, and phone setup; the guidance does not verify every third-party model.

Use heart-rate readings as wellness information
Samsung describes Samsung Health as a fitness and wellness service, not a tool for diagnosing or treating disease. Samsung Health Monitor likewise warns that its information is not intended to diagnose, cure, mitigate, treat, or prevent conditions. Do not interpret its output or make clinical decisions without consulting a qualified healthcare professional.
