What about using the iPhone’s location-based technology for health? This is an extension of a program ISIS does, in that text participants get SMSes relative to the time of day. For example, it’s 10pm on a Friday night — you get a text that says, “appoint a designated driver,” or “grab a condom from the fishbowl at ‘x’ Bar or pub.”
With location-based technology, the first thing that comes to mind is if you’re nearby a park or, say, walking along San Francisco’s Embarcadero, this application would tell you to do five push-ups by the giant bow-and-arrow … or something cooler, but you get my drift.
