I wore the watch over the winter for cross-country skiing and jogging. While my Suunto with chest strap measured an average pulse of around 165, the fitbit was around 120, or at most 140. In the case of the Engadine, the watch was in my jacket pocket and was able to measure a slightly elevated pulse. Fantastic performance 😄. Since then I leave the Fitbit at home when I do sport. Good recognition, however, when cycling. Jogging: the pulse rate is closer to the Suuntow value, but the difference is at least 10, often 20 beats/min.

Yes - more accurate than the simple FitBit. But you have to take that with a grain of salt...

Hi GotMailZH. The fitbit Alta HR does not include a GPS tracker, but there is an app from Fitbit itself to record your distance. However, you need to take your smartphone with you on your jog and have the GPS function turned on.

You can select a specific workout, then start it and stop it again. The calories burned are calculated based on the heart rate.

Only the steps, the distance is calculated via the entered stride length. But I don't find the part very good anymore, the strap is torn :-( Have switched to the Flex 2
