As part of the Digital Urban Living project we have developed our first iphone app, which is now available in app store:

The climate trend app is an innovative and different way to keep up with news, opinions, emotions and environmental sensors before, under and after COP15, the United Nations Climate Change Conference in Copenhagen (December 7-18, 2009).

The app is not simply a newsreader, a social network, a measuring apparatus or a game. It’s a bit of all of that, and more.

* The ocean level indicates the climate situation right now. The worse the situation, the higher the water level. The level is not an exact measure but a reflection of many impressions.
* The ice floes that emerge from below are opinions, articles and readings from CO2 sensors in Copenhagen.
* Tap an ice floe to investigate it further.
* If you are a Twitter user, you can influence the situation, both in the application and through other Twitter applications (by adding #jpcop15 in a tweet).
* You can follow other people and see what they think and how they feel right now about the climate situation.

The primary language in the app is danish. We have implemented both an OpenGL ES1.1 version and a OpenGL ES2.0 version.
