After testing the Jawbone Up 3 , which left us very mixed impressions despite a beautiful mobile application and an effective analysis of sleep phases, it was legitimate to attack its main competitor: the Fitbit Charge HR. This bracelet, competitor by the price and features, usually receives great praise from the specialized press, but also from those who already use it. But does he deserve these flattering comments?



If we complained a bit about the look of our Jawbone UP 3, we are not much better served with this Fitbit Charge HR. On the side discretion, it will iron since it is 21 millimeters wide and more than one centimeter at its maximum (at the screen). Half the width, but still as thick, the UP 3 left us a much better feeling finally. It must be said that it was much more comfortable to wear because the HR Charge is a real pain on the wrist: it must indeed tighten it for the heart rate sensor is effective. A sensor that is also prominent and will leave pretty marks on your skin.


In addition, the product is not really elegant with its mosaic-like rubber that acts as a dust trap. The screen gives a little contrast to all this, just like the aluminum gray tie. Otherwise, the bracelet does not look hyper strong because of its flexibility. To see after several months of use and intensive attacks of sweat and other toxins, if we do not find it in lint.


When we try to learn about the plastic of this bracelet, we find for only indication “elastomeric material”. We have tried to ask Fitbit if they can say more, but the firm does not visibly communicate on the design of this bracelet.



What can your Fitbit Charge HR measure? All the same as the Jawbone UP 3 in fact, and it is the most affordable model of the firm to ship a heart rate sensor. And unlike its competitor, it can take your heart rate constantly, from the moment the sensor is in contact with your wrist. So, we can have a constant overview of his pulse. We still wonder why Jawbone does not offer this feature, yet very useful for sports sessions. As a result, the HR load measures the number of steps taken, the number of kilometers, the active minutes, the calories burned, as well as the stages mounted thanks to its altimeter.
