With the 2012 U.S. Open right around the corner - things get under way tomorrow - The United States Golf Association has released an official Android app to allow fans to follow the action on the go right from their phones.

The app is full of information for users to sink their teeth into, from full course details and information about each hole to biographies for each player competing.

Although the application is available to everyone, live video functionality is only available to view within the United States. For those of you in the US, you can look forward to live marquee groups and hole coverage in the app. There are no Wi-Fi only restrictions in place, so you can view the stream over Edge or 3G if you're away from home. Keep an eye on your data though, as it'll likely disappear quite quickly if you use the app heavily. If you're driving, it's probably not a great idea to watch anything, but you can take advantage of live ESPN radio coverage instead.

If you aren't dedicated enough to watch events unfold live, then you can still view highlights on demand whenever you like. Presumably, this is available outside of the US, as the app description only specifies that regional restrictions apply for live video, but we'll have to wait until next week before we know for sure.

Of course, not everyone is lucky enough to have enough time on their hands to watch live, so if you want to quickly check scores throughout the day, you will be able to use the real-time scoring updates feature in the app. This includes the current leaderboard as well as starting times.

Needless to say, this app is a no-brainer for golf fans; it's packed full of features and best of all it's completely free!
