I bought a tomtom touch. Then downloaded the app Runekeeper to synchronize the heart rate and receive the notifications of it, during the exercise. But this app and none of the others I have tried can read the HR and show at the app display.
I tried in a Samsung Galaxy J2 and an Iphone 5C, always with bluethooth on. They both recognize the watch.
The only way I can see my HR is when i touch the watch display.
How can I display the HR in those apps while running?
