Probably the best interactive app to follow the London 2012 Olympic Games, with Kiip Rewards integrated. With mock-ups already running, in this app you can:
1. Follow your favorite countries and get updated when they win or lose.
2. Predict who will win and get notified if you were right or not
3. See complete event schedule with participating countries (in your local time zone)
4. Check medal count for all the countries
5. Talk about Olympics
6. Read Olympic news
7. Receive events results and ranking of countries for multiple team events
Beautiful and well organized interfaces.
Until Olympics start, this app will be setting up mock-up competitions and declaring winners, so you can use this app as if Olympics are happening right now.
More features will be added with time.
