Average heart rate

Which average heart rate? For an activity it is always displayed in the activity.

Average per a day. 

I don't see that it would be a useful value. How are you going to use it?

If you do several hours of training the average HR will be higher, without any training it will be lower. It doesn't say much.

You are lucky  

I have problems with my heart, so this information is the most important for me. The average heart rate is shown in Zepp for example.

The heart rate is not particularly accurate and the values you see are the 2 minute averages. All highs and lows during that time are missing. 

If you need accurate heart rate logged when not in an activity and for medical use you should use a different device.

This function is presented in other programs for smart watches. Zepp for example.

For a correct average, the measurement should be taken every second. Does Zepp measure every second, and does Zepp output THIS average? I am not aware that Zepp outputs a measurement every second.
