Green news on iPad, iPhone

We know you like our news, comment and galleries - and thanks very much for that - so we have worked with app developer Taptu to create a new way for you to enjoy our journalism: a free environment news app for iPad and iPhone.

The app is built by Taptu and powered by the Guardian's content, through our Open Platform.

What you get is a choice of story streams, such as climate change or wildlife, which you can tailor to your own tastes. You can also enjoy our incredibly popular picture galleries.

Navigating is easy using the touch interface and you can share stories on Facebook, LinkedIn and Twitter with a tap of the finger, or save them for later with Instapaper, Read it Later or Taptu's bookmark stream.

We have also included streams from some of our partners in the Guardian Environment Network, including Business Green, Yale Environment 360, Mother Jones's green channel and the IPS Inter Press Service, as well as others such as Reuters environment news. That means you can get all the latest green news in one place.

I hope you'll download it now and give it go. I think it's fantastic and we are already thinking of new features to add to later versions. So, if you like it, do let us know and, if you don't, let us know why.
