The Fitbit Versa 4's heart rate monitoring has seen mixed results with software updates. While some updates aim to improve heart rate tracking accuracy, user experiences vary significantly.
Firmware Update 210.26
The firmware update version 210.26 for the Versa 4 was released with the promise of improved heart rate tracking accuracy during exercise, thanks to advanced Google machine learning algorithms[1]. However, some users have reported that despite these updates, the heart rate monitoring has not significantly improved. For instance, some users noted that the heart rate readings remain inaccurate, especially during intense workouts[2].
General User Experience
Many users have expressed disappointment with the Versa 4's heart rate accuracy, even after updates. For example, during high-intensity activities like boxing or kickboxing, the device often fails to provide accurate readings, sometimes displaying "--" or significantly underestimating heart rates[2]. This issue persists despite attempts to adjust the device's fit or position on the wrist[4].
Impact of Machine Learning Updates
Google's integration of machine learning algorithms is intended to enhance heart rate tracking and other fitness metrics[7]. However, some users have reported that after updates, their heart rate readings are lower than expected, which could be due to the new algorithms providing more conservative estimates[4]. This change might reflect a shift towards more accurate but less generous heart rate tracking, potentially aligning better with other devices like the Apple Watch[4].
App Issues
Separately, recent updates to the Fitbit app have caused issues with heart rate data display and tracking, leading to missing historical data and inaccurate zone tracking[9]. These app issues are distinct from the device's hardware performance but impact the overall user experience.
In summary, while software updates aim to improve the Versa 4's heart rate monitoring, user experiences indicate that significant challenges remain, particularly during intense physical activities. The integration of machine learning may offer more precise tracking, but it also introduces new inconsistencies that users are still adjusting to.
