The watch does not have to move, it should stick to the wrist quite well. You also have the option of pairing it with a chest strap, which is usually more accurate.
Hello Steffi
I have a htc one m9 and have 2 watches and my handsfree in the car connected via Bloototh. From my point of view this should also work for you....
Everything that is Android is no problem. iPhones, on the other hand, are another matter.
First: I have the watch and am very satisfied with it, although the battery time is a bit short. On the other hand, you can connect the USB charging cable "anywhere".
No, the watch does not need to be connected to a smartphone at all.
No, this function is not integrated as such. Although you can see the intensity of your training by means of the heart rate zones, exceeding or falling below the limits is not signalled by sound or vibration.
