How do I get the counter to track my water and food intake?
You will need to log your water intake on the tracker itself. You don't log food intake on the tracker; instead, logging diet is just a simple "Yes" or "No" to the question "Did I follow my diet today?"
This video shows how to journal on the tracker itself: http://help16.striiv.com/support/solutions/articles/3000061711-journaling-from-your-tracker
