Me and a couple of friends created a Euro 2012 app (0.99) support us GAF!
It is ranked No. 1 in Paid Sports section. Around 100 overall.
Official app website: www.matches.net
Nice. I would buy it, but I don't really care about the Euros If you make an app for the CONCACAF Qualifiers, or Champions League/Europa League/Bundesliga, I would buy it.
Just curious, from what site are you getting the info (red cards, goals, etc)?
