With yesterday’s wild weather and the usual close battle likely, you don’t want to miss a minute of U.S. Open action from Merion over the next few days—and perhaps even into Monday. You don’t have to now that the USGA is offering free, user-friendly apps for iPhone, iPad, and Android devices. The apps have been updated, especially the one for iPad, with more information on players (scorecards, stats, starting times, etc.), as well as detailed information on every hole. All the apps also feature live HD video streaming, real-time scoring, updates, news, and photos. There’s even the option of receiving updates on favorite players sent directly to your mobile device. Apps are downloadable from iTunes and the Google Play Store. Of course, there's always the TV.
