From the announcement:
Could you create an app that will appeal to mobile device users and help them to engage with nature? The app that best helps bring people closer to nature will win a £5,000 prize.
The app should be innovative, available to as many people as possible on Android, Windows Mobile, or iOS and offer new or improved ways for people to get the most from nature.
The My Environment project aims to bring together information about the world around us into one place, to help people connect with nature. It looks at how the UK is responding to environmental challenges, as well as finding out about your local flora and fauna. They’ve made a whole load of data openly available on their data download site which you can use for the App competition.
The competition deadline is 17th March 2013 – all the details are on the competition page. Good luck!
