Currently, you can view variables at specified time intervals, like heart rate. I am suggesting to not only view, but correlate variables at these intervals.

I extracted my data and played with it, and found a wave feature in my heart rate that roughly matched with my anxiety over the past year- my HR responded to stressors over the course of months.

So I used some code I wrote and extracted the specific data related to those time intervals, and found correlations between variables and my HR at those intervals. These correlations then suggested things that could impact my HR, to mediate the anxiety.

I am suggesting to not only view the data at specified time intervals, but to correlate over those times. It seems like a lot for an app, so maybe the web version?
