Turn off … Lighten up … Relax … Celebrate.

Organized by World Wildlife Fund, Earth Hour takes place from 8:30-9:30p (EST) this Saturday, March 26.

The annual campaign now has an app of its own – an iPhone app that guides you through Earth Hour’s many activities and happenings throughout the world – for the hour, and beyond. In addition to extending Earth Hour beyond its given 60-minute time period, the app aims to expand the geographic reach of Earth Hour.



The app provides a list of positive actions you can take to participate in achievements that go beyond Earth Hour. To that end, the WWF and creative group Leo Burnett will be tracking individual and global checkins and achievements within the Earth Hour app to gauge participation and impact around the world.

According to a Leo Burnett Group rep, “The entire interface was created out of discarded boxes and paper. Everything was drawn by hand – even the badges were hand-sewn.” (source)

It’s compatible with iPhone, iPod touch & iPad. View in itunes. Version 1.2 now has added Twitter functionality to share your checkins.
