Difficulties to have benefits of using this app

I track since some time, more than a year, its a good touul for reflection but beaides that I can't seem to use any other benefit feom it. The statistics are complicated? Maybe its what I am tracking is useless in the end. I don't know. I have a chronic illness I should add. So I don't know how to extract more knowledge feom this app about myself. Does someone has some guide or anything similar?
