Pretty great-looking numbers, although I don't know what your HRV measure is—the differ. You need to establish a baseline over a few weeks and compare to that in order to pick up daily signals. Presumably your app does this. Both the daily values and the degree of the variance over, say five days or a week, are meaningful.
