iPhone Giveaway of the Day - GT2 Green Travel Carbon App

GT2 means the second dev path to a full app beyond the PoC. The 2 level is a quantum leap for the original POC app by virtue of: complete trip history, and enhanced model and trip control all in a free app whose sources are in github.com/renrenjuan. With this 3.0.1 version the 2 series is complete. It was MIA on App Store for nearly a year before this final update, but it is now using my DSAP stack and will be maintained to keep stack current. It is free, verified, and fit for no-frills function of getting the carbon footprint or savings of a trip or itinerary.

The tracking mechanism has been proven and the screenshots were not prepared to show real trips, a few real trips will give you a sense of how it works.
