This one is really great for World Cup, keep you always updated. Great hunt @mayowa-eu.

As per my evaluation below :

Pros :

• You will received notifications on Match Schedules between country teams and at the same time you can easily check with their scores for those active games.
• Simple and yet very easy to look at, just into your desktop's task bar. Only a simple click will do and you will see all the details immediately

Cons :

• Limited to current World Cup events (scores and schedules)
• It would be better if they do have news feed so world cup fans will be updated on current news related to world cup.
• Application only supports on MacOSX
