The app lets you search through Kickstarter's current projects, watch any promotional videos, and keep track of when interesting projects are about to end.
One issue might be the use of Kickstarter's name and logo - as an unofficial app it's unlikely these will permitted so I'm expecting a name change in the near future!
The app is a free download, and you can pick it up via the AAWP App Directory or the online Windows Store.
