The NYTimes Freakonomics blog poses that question.  Sad to say, according to Mobclix, the urinal test app gets far more downloads.

Our DonateLives app was featured in the Economix blog on the New York Times recently.  It was definitely a very nice surprise from Dr. Thaler (who inspired us to make the app in the first place).  Hopefully this extra exposure will get more people to download the app and by extension increase the amount of organ donors out there.  We're all about making a positive impact out there in the world and this is just one small step towards that end.
