We'll be honest---we had no idea what Trello was till just a little while ago. Evidently it's another free cloud-colloboration service that allows your group of co-workers, friends or colleagues to work together on a project. In short, you create boards, people can add notes and media to said boards and you get a timeline of those changes and who made them.
Now that we think about it, that does sound useful. So it's nice to know that (a) if you already use Trello or (b) you think Trello could be useful to you, there is an app for that.
Trellizzo, by Intertouch Media Technologies, is a free Windows Phone app that will access your account and evidently allow you to continue your collaboration via your WP7 device on the go--or at they very least, track those changes. The app is a little rough for a v1.0 with no Mango support...yet. But the devs are actively looking to update the app and are looking for user feedback (done through the app) which sounds good to us. Plus it is fast and nice looking.
