ecoCheck Papier is a mobile app giving the user an informative hands-on experience with fun. Civilizational eras are known by the dominant materials of the time, whether Stone, Bronze or Iron Ages. Which name would today’s age deserve? While a definitive answer is open, it is certain, that as resources become scarce, all of us must adopt economically sustainable choices. This key trend towards an ecologically conscious usage of resources is seen today in the many recycled products available. ecoCheck Papier thus strives to not only portray paper as the everyday material that we know, but also to make the user aware of its environmental impact. Videos and tools are provided with essential and surprising facts, as well as a self-check test comparing the user’s consumption to the national average. What really sets the app apart is the challenge to grab some paper and learn to recognize different kinds of paper where all you saw before was a blank page. Put sheets on the screen of your tablet and activate an ecoCheck’s light table with an integrated guided tour. Once through, you will have probably unlocked another feature, a folding manual for a shot glass - made of paper: a great trick for your next party.
