Your research mirrors my experience

Posted by tgreene on 14 Mar 2018 at 03:19 GMT

Your report reflect the results I've observed with two fitbit Charge 2's I've owned Jan-Mar 2018. The heart rate can be off by 10 bpm when sedentary, and I've had it reading 30 bpm too low during exercise; as well as reading 20 bpm too high during exercise. (I compare it with manual carotid artery measurements, usually around 140 bpm, so I have no doubt of my manual rate). Hopefully fitbit can improve their algorithms!

Hi, I'm happy to hear that our research mirrors your experience and that of many other people like you, who just look for a reliable instrument for measuring a vital parameter!
