Max heart rate widget error

I see your watch isn't connected to the phone. Connect it, sync again, and the heart rate widget should update.

The heart rate widget shows the all day heart rate which is using an average value and that misses out on all the short peaks. It is very unlikely that you will see the max heart rate from an activity in the heart rate widget.

It is an important error of the app. 

I can see my hearth rate in te activity, but not in the heart rste widjet 

That looks like an error. Do you wear your preferred activity tracker during that time? Do you wear the same watch during the day as during your sleep?

My phone was on low battery when i started running, and swich off during the activity.

During the forced shutdown the monitoring file containing the HR, was lost. You could try recovering it with a USB storage repair tool such as Recuva, but I think the chances are rather slim.

Yes, it is an error. 

Icwaer it all the time and i only have one watch.

How can i solve this error?
