There are plenty out there and I looked at a few but most were not what I was looking for. They were too bulky, had too many apps, or just flat out too little info. I had hoped to find just an app that shows the schedule and no results, as I will DVR the games and watch at night, but could not find one. Ended up downloading an .xls file someone created that has just the schedule. Works easily to just open it via Dropbox and take a peek at what's going on.
If you want a lot of news and stuff surrounding the Euro Cup I'd suggest to just use a good local sports website and forget the whole app thing.
