This can be easily the best app that I had used on Windows Mobile (Windows Phone) so far this year. It is fluid and it looks like the type of app that will appear on Windows Phone 7. Best of all, it is free and it is into the 0.3 beta version already.
I really hope the development can use this technology for other apps. If you are following closely on the World Cup 2010, this app is really good. Too bad, it does not do live update. Instead, you can update manually and it polls the data from Fifa.com. It is using the some UX concepts from Windows Phone 7 panoramic UI.
Here is a video of the app at work.
