The GoBe2 doesn’t track heart rate the way most other devices do.
Healbe seems to focus more on that and frankly, that seems to be the growing trend among fitness trackers. Most people are more focused on their RHR anyway.
This is, however, where one of my gripes come into play.
I found the GoBe2 heart rate measurements to be very inaccurate during periods of exercise.
You’ll notice that there’s a difference of almost 50 BPM between the Gear S3’s optical sensor and the GoBe2’s piezo sensor. (Pictured above)
My understanding is this is a limitation of the sensor technology. That being said, throughout the day, during normal activity, the GoBe2 was spot on when compared to my Gear S3. Again, for me, this isn’t a deal breaker because I’m personally more focused on my resting heart and making changes in my life that help to lower it.
I can say that when my energy balance is in the negative for a few days, I end up showing weight loss. It seems to be a solid indicator that I’m heading in the right direction.
