The Samsung Galaxy Watch 7 is equipped to monitor both heart rate and blood oxygen levels during workouts, making it a versatile fitness companion.
Heart Rate Monitoring
Accuracy and Functionality- The Galaxy Watch 7 utilizes a new optical heart rate sensor, which has shown promising results in accuracy during various workouts. In tests comparing its readings to those from a chest strapâconsidered the gold standard for heart rate measurementâthe watch performed well, with average heart rates differing by less than one beat per minute[1][2]. This level of accuracy was consistent across different types of workouts, including running and indoor cycling.
- Users have reported that the watch can effectively track heart rate fluctuations during exercise, maintaining close alignment with chest strap data. For instance, one review noted that the watch accurately captured the rise and fall of heart rates during workouts[2].
Challenges
- Despite its capabilities, some users have experienced issues with heart rate accuracy, particularly during high-intensity activities. Reports indicate that the watch occasionally underreports heart rates, sometimes showing values significantly lower than actual readings[3][5]. These discrepancies may be attributed to factors such as sensor placement or wrist movement during exercise.
Blood Oxygen Monitoring
Oxygen Saturation Measurement- The Galaxy Watch 7 also includes features for monitoring blood oxygen levels (SpO2). This function is beneficial for assessing respiratory function and overall fitness levels. However, it's important to note that while the watch can measure blood oxygen levels, this feature may be limited or require specific conditions for accurate readings[2][4].
Integration with Samsung Health
- Both heart rate and blood oxygen data can be accessed through the Samsung Health app, which allows users to track their fitness metrics over time. This integration provides insights into health trends and can help users adjust their workout routines accordingly[4].
In summary, the Galaxy Watch 7 is capable of monitoring both heart rate and blood oxygen levels during workouts, offering valuable data for fitness enthusiasts. However, users should be aware of potential accuracy issues in certain scenarios and consider using additional monitoring methods if precise data is crucial.

How accurate is the blood oxygen level monitoring on the Galaxy Watch 7
The accuracy of blood oxygen level monitoring on the Samsung Galaxy Watch 7 has been a topic of interest among users and researchers. Hereâs a detailed overview based on available information.
General Accuracy
- The Galaxy Watch 7 is designed to measure blood oxygen saturation (SpO2) levels, and while it is capable of providing readings, its accuracy can vary. Users have reported mixed experiences, with some noting that the watch sometimes displays significantly lower SpO2 levels compared to standard medical devices, especially during sleep or high movement scenarios[1][5].Measurement Conditions
- To achieve more reliable readings, it is recommended to ensure that the watch fits snugly on the wrist and is positioned correctly. For optimal results, users should remain still during measurements, as movement can lead to inaccuracies[1][3]. Some users suggest taking multiple measurements and averaging the results to improve reliability[1].Comparative Studies
- Research comparing smartwatches, including the Galaxy Watch series, to clinical pulse oximeters indicates that many wrist-worn devices can achieve clinically acceptable accuracy under controlled conditions. A study found that popular smartwatches met acceptable standards for SpO2 measurement, although specific performance metrics for the Galaxy Watch 7 were not detailed in this study[2][4].User Feedback
- Feedback from users highlights that while the Galaxy Watch 7 can provide useful insights into blood oxygen levels, it may not always be as accurate as dedicated medical devices. Instances of readings dropping below 90% during sleep have raised concerns among users, especially when these values do not align with those from finger-based pulse oximeters[5].- Some users have experienced discrepancies where the watch reported low SpO2 levels while a medical device showed normal levels. This inconsistency has led to skepticism about relying solely on the watch for critical health monitoring[5].
Conclusion
In summary, while the Galaxy Watch 7 can monitor blood oxygen levels and provides a convenient way to track this health metric, its accuracy can be influenced by factors such as wrist placement and user movement. Users are advised to approach its readings with caution and consider corroborating them with more traditional medical devices when precise measurements are necessary.Citations:

Does the Galaxy Watch 7 require a specific app to monitor heart rate and blood oxygen levels
To monitor heart rate and blood oxygen levels on the Samsung Galaxy Watch 7, users need to utilize specific applications, primarily the Samsung Health app and, for advanced features, the Samsung Health Monitor app.
Required Apps
1. Samsung Health App
- The Samsung Health app is pre-installed on the Galaxy Watch 7 and is essential for basic heart rate monitoring. Users can access heart rate data directly through this app by navigating to the heart rate section. This app allows for continuous heart rate tracking and provides insights into overall fitness levels[1][6].2. Samsung Health Monitor App
- For more advanced features, such as irregular heart rhythm notifications (IHRN) and ECG monitoring, users need to download and activate the Samsung Health Monitor app. This app enables additional functionalities like blood pressure monitoring and detailed heart health assessments. Users must update this app through the Galaxy Store to access these features[1][6].Functionality Overview
- Heart Rate Monitoring: The watch continuously tracks heart rate, which can be viewed in real-time through the Samsung Health app. Users can also set alerts for high or low heart rates.- Blood Oxygen Levels: The Galaxy Watch 7 can measure blood oxygen saturation (SpO2) levels using the Samsung Health app. However, users should ensure that the measurement feature is added to their watch interface for easy access[7].
In summary, while basic monitoring can be done through the Samsung Health app, advanced features require the Samsung Health Monitor app to be fully functional on the Galaxy Watch 7.
