How reliable is the Versa 4's automatic workout detection feature

Accuracy and Efficiency:
- Auto-Detection Issues: Some users have reported that the Versa 4 is less efficient at auto-detecting exercises compared to older models like the HR Inspire. Activities such as swimming, walking, and biking may not be consistently recognized, leading to inconsistent tracking in the user's logs[7].
- False Positives: The feature can sometimes detect activities incorrectly, especially if the user is performing tasks that involve arm movements similar to those during exercise, such as preparing inventory in a store[7].
- Lack of Real-Time Alerts: Unlike some other smartwatches, the Versa 4 does not provide real-time notifications when it detects and starts tracking a workout. Instead, it records the activity in the Fitbit app without alerting the user[2].

User Experience:
- Many users have expressed frustration with the automatic detection of walks and other short activities, which can clutter their workout logs. Some have found it necessary to disable auto-detection to avoid these issues[3][7].
- The feature can be turned off for specific activities by adjusting settings within the Exercise app on the watch or through the Fitbit dashboard, but this process can be cumbersome and may not always work as intended[3].

Comparison to Manual Tracking:
- Manual tracking allows users to have more control over what activities are recorded and when. This approach is preferred by those who want precise control over their workout logs and avoid false positives[7].
- However, manual tracking requires users to remember to start and stop tracking each session, which can be inconvenient for some users.

Overall, while the Versa 4's automatic workout detection feature is convenient for casual users, it may not be reliable enough for those seeking precise tracking or who engage in a variety of activities. Users may find it beneficial to manually track workouts for more accurate and personalized data.
