Your football (soccer) team is playing, you are out at the supermarket with the family and desperate to know the scores… Yes, there are many apps, some even send you notifications but probably the quickest way is to access LiveScore.
LiveScore.com website has been running since 1998 but they have been providing a free iPhone app for the last year and a half. The app is very clean, shows you all the games for the day and those playing live right now with of course live scores.
The scores can be refreshed as often as 30 seconds to 180 seconds or you can manually force an update if you get impatient or nervous hoping for the final whistle to arrive.
