If one is in a more relaxed state the variation between beats is high.

A number of published literature has reported that physiologically heart rate variability HRV in patients with postural orthostatic tachycardia syndrome POTS to be greatly confounded by age sex race physical fitness and circadian rhythm. So if the heart rate is 60 beats per minute. Within that minute there may be 09 seconds between two beats for example and 115 seconds between two others.

And since each app uses a unique scale its hard to compare the numbers across different programs. HRV is literally the difference in time between the beats of the heart. And while that may not sound that profound its actually an important metric to use if you know how to find it -- unlike heart.
