This app indicates my anxiety and desperation level as they rise, from the moment I leave the comfort of my partner and apartment until I return. The pattern of work, or any other daily event, likely has a direct relation to the level of anxiety, so that can be a fairly accurate gauge for time. We all have things we do with regularity to relieve stress, so whatever that is, it can be plugged into the app and the countdown to your next fix can begin.
