The Samsung Galaxy Watch 7 has been evaluated for its heart rate accuracy in comparison to other smartwatches, particularly the Galaxy Watch Ultra and traditional heart rate monitors like the Polar H10. Hereâs a detailed overview of its performance.
Heart Rate Accuracy Overview
Improvements Over Previous Models
Samsung has claimed enhancements in the optical heart rate sensor for the Galaxy Watch 7, aiming for better accuracy than its predecessor, the Galaxy Watch 6. The new sensor design is intended to provide more reliable heart rate readings during various activities[1][4].Comparison with Other Devices
1. General Performance: In initial tests, the Galaxy Watch 7 demonstrated a correlation coefficient of 0.97, indicating a strong agreement with reference devices in higher heart rate ranges[2]. However, it struggled more in lower heart rate zones, where it occasionally failed to detect dips accurately[2][4].2. Cycling Performance: The watch's performance was notably less reliable during cycling activities. Reviewers reported that the optical sensor had difficulties capturing heart rate fluctuations effectively while cycling, which is a common challenge for many optical sensors[1][4]. In contrast, devices like Garmin and Apple are often cited as performing better in this regard[4].
3. Comparison with Galaxy Watch Ultra: While both the Galaxy Watch 7 and the Ultra share similar sensor technology, the Ultra generally showed superior accuracy across various activities, particularly in tracking heart rate during intense workouts[1][5]. The Watch 7's performance was described as being "in the C+ territory," suggesting it was adequate but not exceptional compared to more advanced models[4].
Variability and Reliability
Despite some improvements, users have noted variability in heart rate readings across different activities and conditions. For example, while one spinning session yielded satisfactory results, another showed significant deviations from expected heart rates. This inconsistency raises concerns about its reliability for serious athletes or those relying on precise metrics for training[2][4].Summary of Findings
- The Galaxy Watch 7 shows improved heart rate accuracy compared to previous models but does not consistently match the performance of higher-end devices like the Galaxy Watch Ultra or dedicated monitors such as the Polar H10.- It performs well in higher heart rate ranges but struggles with lower rates and during cycling.
- Overall, while it offers decent functionality for casual users, athletes may find its accuracy insufficient for rigorous training needs.
In conclusion, while Samsung has made strides with the Galaxy Watch 7's heart rate monitoring capabilities, it still faces challenges that may impact its attractiveness compared to other leading smartwatches in the market.

How does the Galaxy Watch 7 compare to the Apple Watch in terms of heart rate accuracy
The Samsung Galaxy Watch 7 and the Apple Watch series, particularly the Apple Watch SE and Series 7, have been compared in terms of heart rate accuracy, revealing some interesting insights.
Heart Rate Accuracy Comparison
General Performance
Both the Galaxy Watch 7 and Apple Watch demonstrate strong heart rate tracking capabilities. In various tests, both watches showed similar heart rate readings when compared to traditional heart rate monitors, indicating a high level of consistency. For instance, during a side-by-side comparison, both devices yielded nearly identical results, with only slight discrepancies noted between their readings[1][4].Specific Findings
1. Correlation Coefficient: The Galaxy Watch 7 achieved a correlation coefficient of 0.97 when compared to reference heart rate monitors, indicating a strong agreement in higher heart rate ranges[2][3]. This performance is comparable to that of the Apple Watch, which has also been noted for its accuracy in similar conditions.2. Activity-Specific Performance: Both watches performed well during steady-state activities but faced challenges during dynamic exercises like cycling. The Galaxy Watch 7 struggled more with detecting rapid changes in heart rate during cycling sessions compared to the Apple Watch, which generally maintained better accuracy in fluctuating conditions[2][5].
3. User Experience: In practical tests involving walking and other activities, users reported that both smartwatches provided heart rate data that closely aligned with manual measurements. However, the Apple Watch SE was noted to have slightly better performance in terms of overall accuracy during these tests[4].
Summary of Findings
- The Galaxy Watch 7 offers robust heart rate tracking capabilities with a high correlation to reference devices, especially in higher heart rate zones.- The Apple Watch, while also accurate, tends to perform slightly better in dynamic situations and has a proven track record for reliability across various activities.
- Overall, both devices are suitable for casual fitness tracking; however, serious athletes might prefer the Apple Watch for its consistency during varied workouts.
In conclusion, while both the Galaxy Watch 7 and Apple Watch provide reliable heart rate monitoring, the Apple Watch may have a slight edge in dynamic activity scenarios.
